    What electrical component would I use to keep the the current from turning on a light when the thermostat is on. I only want it on when I turn the override switch to the on position. If the switch is off and the thermostat is activated the override light is also turned on. I know this is a easy solution but my electronics are rusty and my books are packed somewhere in my basement. Any suggestions are appreciated.

    A diode.

    Hi Dennis,


    I tried a diode, can you recommend size and type of diode? The one I used was a silicon
    1000V 6A Axial Lead Silicon Rectifier Diode

    Thanks

    Is that 120V AC or DC?

    Then a diode won't work.
    The easiest solution is probably to use a double-pole switch with one pole connected only to light the bulb.
    If you have to stay with that SP switch then you could use that to power a DP 120VAC relay.
