Question:

Can you connect it so that a light will light up when the door is open.

Answers:

  • Posted by Geoff Hampson on Friday, 20 January 2012
    The door contact will be closed circuit when the door is closed, so if you connected a power source, the door contact and the light in series then the light would be on when the door is closed, rather than when it is open. It is however possible to use a transistor to drive the light, in which case you would want to connect the door contact between the 0v supply and the base of the transistor. You then just need a pull up resistor between the base and the positive supply to make sure the transistor is held in an on state when the door contact is open.
