Hi all,
I need a circuit that will operate a relay for aprox 10 seconds when power (12V) has been applied. After the 10 seconds the relay should switch back. Power will contine to be applied, but the relay shouldn't switch over again, until the power has been disconected & reconected again.
I know this should should be a simple circuit, but I can't seem to get the relay to switch over for 10 seconds. I was trying to avoid a 555 circuit, so I can make this on a strip board.
This is to fix a problem with my car.
I'm currently using a switch everytime I start the car, which disconnects the coolent sensor, then start as normal, before toggling the switch again to reconnect the sensor.
Any help would be greatly apreciated.
