Schndr Light Switches.

Zoomup

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.

    The switch featured looks reasonably easy to wire by anyone who can understand the simple markings, and presuming that working space and lighting are acceptable.

    The problems will come from not just from from DIYers but also from so called electricians who have no real understanding of electrical circuits and can only replace a switch or other component by exactly replicating the existing connections.

    I.E. remove wire from top left terminal of old part and insert in top left terminal of new part, repeat with other wires. If the new part has a different number or arrangement of terminals then it all goes wrong.

    When working for a well known maintenance contractor I found many cases of equipment “that cant be repaired because the parts are not available”  And these were not specialist components but generic relays, batteries, contactors, lamps, ballasts and batteries.

    Fluorescent lighting ballasts with different numbers of connections caused total confusion.

    As did replacing a single way light switch with a 2 way one ! Extra terminal=panic.
