I need to draw up and make a circuit for a i/c spray system.
I have a sprung toggle switch and the solenoid and everything else.
problem is I dont want it to be a simple on/off affair.
Ideally when the sprung toggle is activated the circuit provides a one second burst onto the i/c.
as the toggle switch returns to the off state the system then re-arms ready for the next shot.
does this make sense at all?
can anybody out there help me out.
I have looked on the maplins site and rs components and they seem to be about £20 and adjustable, but never exactly what Im after.
thanks

Get hold of a std WS switch if you can, they have a timed relay inside which is adjustable (time wise)

Maybe easier?

The UK STi 7/8 IC spray uses a 3 sec self resetting timer relay.
All the dash button does is kick start this relay.

The WRX ra has the relay inside the switch

spoke to Glenburgie subaru (breakers and suppliers) and they only sell as a kit at £150+ the dreaded.

I have the toggle switch (sprung), bottle, regulator and the solenoid. Basically everything else except the bloody timer so it looks like we will be making the 1 second oneshot stable magiggy thing diagram supplied by Nezz10.

coupled with water injection and cold air feed/box/scoop looks like it could be time to wrap up , theres a cold spell coming
