1 Gang - 2 Way Switch
Hi
I am new to Electrics, but have a *basic* understanding of electricity. My scenario is that I want to install 2x Spotlights in my back garden. I require them to either be switched on as a result of "heat activation"(normal infrared activation build in the DIY spotlights) or "permanent on"(i.e. I switch them on and they stay that way till I switch them back to "heat activation". I looked at possible ways to connect the 2 up and I require is a switch (for the purpose of keeping controlling the scenarios above simple) that can control switching off 2 live wires in 1 switch. In other words, It should have in stead of a ON and OFF (like an conventional switch) also a MIDDEL phase which controls the 2nd Live wire. Thus, FOR ALL 2 LIGHTS OFF: Live---------o o---------------^^^^^------||(N) (Dead) o---------------^^^^^------||(N) (Dead) FOR LIGHT 1 ON, LIGHT 2 MUST be OFF: Live---------o____o---------------^^^^^------||(N) (Glow) o---------------^^^^^------||(N) (Dead) FOR LIGHT 2 ON, LIGHT 1 MUST be OFF: o---------------^^^^^------||(N) (Dead) Live---------o____o---------------^^^^^------||(N) (Glow) What does one call this switch, and where can I buy one ?? Help will be appreciated Arno van Rooyen |

Help will be appreciated Arno van Rooyen It's called a 3-position single pole c/o (change-over) with centre off, but such a beast is not made for standard single wall panels, so use a 3A toggle with thick bush (from RS, Rapid, Maplin or Farnell) and drill a suitable hole in blank panel so that protrudimg bush has a securing nut. Remember to run Earth wire to make metal thread and lever safe. You may find an-all plastic gismo with a similar function available from any auto spares shop. Jim |

This is easily built into a single wall plate, or any other required combination. -- Andy |
