Hello
i have a previous thread on this but the reply's have stopped it is called 'Wireless Remote Controll'
My Problem:
I have a signal coming out of a doorbell output (speaker wires) it is about 2V roughly and can liight an LED, retched told me that if i used a transistor to boost the voltage from the output, then used a LATCHING RELAY i could acheive what i previously tried in my doorbell christmas light problem.
I done some research on these new type of relays and now know they have a cam mechanism, so that when one pulse of power is applied they will 'click' and that power can then be turned off and the relay will stay as it is, and when the same pulse comes back, it will energize the coil and un 'click/ latch' the relay which is perfect for what i need.
I Need:
Thanks, Chris

I Need:
- Some sort of wiring diagram of these LATCHING RELAY's on how to use them, the sort with 2 coils, to get the result i have explained.
- A simple lecture on how to use a transistor to aplify the voltage,
Thanks, Chris
