Making a switch turn on/off another switch

    I tried googling this but I wasn't quite sure what to search for.

    What I am trying to do is make a basic light switch turn on a timer. When this timer reaches 00:00, I want it to turn on another switch which will trigger a wireless buzzer and turn on a LED (in another room).

    So basically when the timer finishes, I need the current from the timer to trigger another switch.

    Any ideas?

    Thanks :)

    An adjustable timer relay will do this for you.
    The live out from your switch connects to the coil of the relay. After the set time that output will switch NO or NC as required.

    Any decent timeswitch will do the job.

    Go to you local wholesalers and as for multi function timer and a retractive switch.

    How you trigger the wireless buzzer will be the hard part. A wireless impulse switch will do it but not every wholesaler will have one.

    If its a low voltage buzzer you could use a second relay with a mains coil.

    I will go looking for some of these today. Doesn't sound too complicated :)

    Well what I am currently using is an old wireless doorbell modified to what I need it to do. So when the doorbell is pressed, it will send current to the buzzer rather than the doorbell chime. All I needed to to figure out with this part was how to trigger that button using electric current :)
