Wireless doorbell to operate and latch a relay

[bhadresh]

I'm trying to use my wireless doorbell to switch off my water pump. The problem is how to use the receiver signal to latch a relay. Search the net but no clear solution found !

I've driven LED from a speaker wire with transistor (doorbell receiver circuit) but don't know how to use this signal to latch a relay. I'm planning to use 6v relay. I've try to drive relay with transistor but no success.

Pl. have me some idea/schematics.

It shouldn't be difficult. Maybe a photo of your wireless door bell will be good.
You can also buy a wireless remote control, which will definitely solve your problem.
