Schndr Light Switches.

I am going to recommend  a certain make of light switches to all D.I.Yers. The make starts with an “S”.

They are just great for causing confusion, especially the two way type as the terminals are not traditionally positioned with the common at the point of a triangle and the L1 and L2 together opposite. Also the loop terminal confuses 'em luvverly. I got a load of work today when the householder had wired up some “S” light switches wrongly. GGGGGGGGGGGGrrrrrrrrrrrrrrrreat as that tiger used to say in the breakfast cereal commercial.

  • So there we are, working in a dim light on a wall switch. The lighting is off 'cos we are working on a wall switch. We have read the installation instructions and have installed thousands of light switches over the years, one way, two way and intermediated switches. We have short wires from the wall box to the switch terminals which does not help the installation, and sometimes we have to work “mirror image” as we can not see the terminals directly. We get used to the terminal positions, then a new design comes out. It takes time to adjust, even for “competent” electricians. Normally we connect up as "second nature" if all light switches follow the same terminal layout, we can even do it correctly in the dim light available or even blind by feel only.
