What I need looks identical to a thread I saw in this forum back in 2006. I've copied the description from hhoncho, and added few words of my own:
I am looking for a circuit which operates a solenoid using a touch sensitive switch. The solenoid is of the magnetically latching type which functions in two directions.
The operation should be as follows:
The touch sensor is tripped, activating the solenoid in one direction and power is maintained to the solenoid as long as the touch sensor detects contact.
The touch sensor is released, activating the solenoid in the opposite direction for a short time (few ms) and power to the solenoid is subsequently removed.
The circuit must operate on batteries; I think something between 9-12 Volts. Power consumption when inactive must be kept to an absolute minimum.
The circuit needs to be Reliable, compact and with zero/minimal delay time.
I hope what I'm looking for is feasible...
I have virtually no knowledge of electronics (I'm an HVAC engineer).
I would like to understand, as much as possible for a dummy, the circuit's components, and whether there is more than one alternative, to achieve the desired solenoid's output in reaction to of the touch sensor's position.
Any suggestions which you feel may help would be greatly appreciated.
Thanks in advance.
