has two variations.
The first version produced only in 1980 has shallow middle hole and a connector
with middle pin (like 766c01 ) does not fit in it.
The second version produced between 1981-90 has deep middle hole and a connector
with middle pin does fit in it.

See photos attached.

The same goes for

The first version produced only in 1980 has shallow middle hole and a connector
with middle pin (like 766c01 ) does not fit in it.
The second version produced between 1981-84 has deep middle hole and a connector
with middle pin does fit in it.

However this one has a third variation produced since 1985 until 1990. The main
difference of this version is that the switches work more smoothly and if one
switch is pressed in, and you press the other switch, the first switch gets pushed
up so that it is impossible to be pressed in at the same time.
The side and bottom of the third variation is also different (oh, I realized
I forgot to include another comparison photo....)
The question is this: should this switch be split in two variations (1st and
2nd) of three variations (1st, 2nd and third)

Similar variations exist for

Hi

I have several 4707pb05 switches (the ones with the circular arrows) and wondered
as to the correct operation. Most operate the motor when a key is pressed and
stop the motor when released, however I have a couple where the motor stays running
after pressing a key and only stops if you press the other key. I suspect the
former is the correct operation but would appreciate any feedback.

Thanks

Hi Steve,

There is no correct or incorrect operation.
What happened is that between 1980-84 TLG produced the switches in a way when
you press and then release one switch, that switch gets released.
Since 1985 TLG changed the internal mechanical design of switches in order to
improve their functionality.

You can read and check the production dates of your switches: few digits are
engraved under the switches. For example 25 1 means 25th week in 1981 or 9 6
mean 9th week in 1986.

The question is if we need to have separate entries for switches depending on
if they were produced before or after 1985 (there are other differences on their
housings as seen in photos I had uploaded)

Thanks for that SezaR, I thought I might have a couple that were faulty.

However the one switch I have that 'holds' the motor 'on' when
you press the switch has 1 01 underneath. I think I will just describe the difference
in my inventory, as if someone is expecting the motor to stay on when the switch
is released they are going to be mightily disappointed if I send them one where
you have to hold the switch down if you want the motor to operate.

Perhaps some description in the catalog entry is needed to indicate that there
are 2 very different versions in terms of how they operate.

Cheers

Steve

You are welcome.
Not sure if you remember but indeed, one of my first orders were from your store
and I asked many questions from you and you took the time and answered them all.
Thanks for that. (in was at that moment that I got addicted to 12v train system
)

  However the one switch I have that 'holds' the motor 'on' when
you press the switch has 1 01 underneath.

I just checked my 12v switches. In the early versions, the production date was
engraved underneath (top middle). The the later versions, it was engraved on
the left side, between the two contact holes. The digits 1 01 in yours are mold
numbers, nothing to do with production dates, and so, yours is the second variant.

  I think I will just describe the difference
in my inventory, as if someone is expecting the motor to stay on when the switch
is released they are going to be mightily disappointed if I send them one where
you have to hold the switch down if you want the motor to operate.

Have you encountered any buyer having this detailed expectation?
Actually what is the functionality of this?

Perhaps some description in the catalog entry is needed to indicate that there
are 2 very different versions in terms of how they operate.

Are you in favor of having separate entries for them?

Note that there should be already two variations of the first variant for

Hi

Thanks for your response and advice regarding the switch motors in regard of
the catalog entries.

I've just checked again and the 4707pb05 switch that operates in a different
way to the other 4707pb05's that I have says 22 0 between the pins, the rest
are xx 6 or xx 8.

Regarding expectation of buyers, as I had 2 different versions I had no idea
what people might expect. I have made it clear in my description though just
so buyers know what they are getting as some may have experienced the older version
and may have different expectations.

If it is clear there are 2 versions (and it seems there are) it may be useful
to have different entries.

Thanks

Regards

Steve

  Thanks for that SezaR, I thought I might have a couple that were faulty.


You are welcome.
Not sure if you remember but indeed, one of my first orders were from your store
and I asked many questions from you and you took the time and answered them all.
Thanks for that. (in was at that moment that I got addicted to 12v train system
)

  However the one switch I have that 'holds' the motor 'on' when
you press the switch has 1 01 underneath.

I just checked my 12v switches. In the early versions, the production date was
engraved underneath (top middle). The the later versions, it was engraved on
the left side, between the two contact holes. The digits 1 01 in yours are mold
numbers, nothing to do with production dates, and so, yours is the second variant.

  I think I will just describe the difference
in my inventory, as if someone is expecting the motor to stay on when the switch
is released they are going to be mightily disappointed if I send them one where
you have to hold the switch down if you want the motor to operate.

Have you encountered any buyer having this detailed expectation?
Actually what is the functionality of this?

The functionality of

later.

  
Perhaps some description in the catalog entry is needed to indicate that there
are 2 very different versions in terms of how they operate.

Are you in favor of having separate entries for them?

Note that there should be already two variations of the first variant for

because in their earliest production runs in 1980, the middle hole were shallow,
and a connector with middle hole would fit in them. So why

because 12v system was sold in UK (or France or Italy) since 1981 (or later).

You might want to move your items from 70026 to 70026b or 70026a because 70026
is marked for deletion, not in any inventory so buyers may not find it in their
search.

  Hi Steve,

There is no correct or incorrect operation.
What happened is that between 1980-84 TLG produced the switches in a way when
you press and then release one switch, that switch gets released.
Since 1985 TLG changed the internal mechanical design of switches in order to
improve their functionality.

You can read and check the production dates of your switches: few digits are
engraved under the switches. For example 25 1 means 25th week in 1981 or 9 6
mean 9th week in 1986.

The question is if we need to have separate entries for switches depending on
if they were produced before or after 1985 (there are other differences on their
housings as seen in photos I had uploaded)

  Hi

I have several 4707pb05 switches (the ones with the circular arrows) and wondered
as to the correct operation. Most operate the motor when a key is pressed and
stop the motor when released, however I have a couple where the motor stays running
after pressing a key and only stops if you press the other key. I suspect the
former is the correct operation but would appreciate any feedback.

Thanks

Regards

has two variations.
The first version produced only in 1980 has shallow middle hole and a connector
with middle pin (like 766c01 ) does not fit in it.
The second version produced between 1981-90 has deep middle hole and a connector
with middle pin does fit in it.

See photos attached.

The same goes for
 
Part No: 4707pb01  Name: Electric, Train 12V Remote Control 8 x 10 with Switch Pattern
* 
4707pb01 Electric, Train 12V Remote Control 8 x 10 with Switch Pattern
Parts: Electric, Train

The first version produced only in 1980 has shallow middle hole and a connector
with middle pin (like 766c01 ) does not fit in it.
The second version produced between 1981-84 has deep middle hole and a connector
with middle pin does fit in it.

However this one has a third variation produced since 1985 until 1990. The main
difference of this version is that the switches work more smoothly and if one
switch is pressed in, and you press the other switch, the first switch gets pushed
up so that it is impossible to be pressed in at the same time.
The side and bottom of the third variation is also different (oh, I realized
I forgot to include another comparison photo....)
The question is this: should this switch be split in two variations (1st and
2nd) of three variations (1st, 2nd and third)

Similar variations exist for

(three variations in total)

4707pb04 Electric, Train 12V Remote Control 8 x 10 with Level Crossing Pattern

was produced since 1983 so it has only two variations similar to the 2nd and
third variations of 4707pb01 (or 4707pb02)

P.S.

The switch

* 
4707pb03 Electric, Train 12V Remote Control 8 x 10 with Decoupler Pattern

was produced between 1981-82 or 83 so this one has only one varaition and no
split is needed.

Similarly, the switch
