Oh Dear another tale of tenby gridswith woe loL
We are currently working in a prison and ALL the existing switches are tenby. No replacements can be obtained they no longer make them. What sort are you after ?? 2 way 20A DP ?? will have a look and see if we have any we have ripped out if your desperate . Our normal approach is to replace them with MK now as we have no other options available to us.
They are the ones that are about 50x25 with the whole front of it a rectangular switch arent they??
Let me know and will see what we can do for you .
