barracj Posted December 12, 2003 Report Share Posted December 12, 2003 Hello,This is my first post. I'm trying to modify a circuit so it can be turned on via a SPST slide switch. Currently the circuit (an OEM; un-modifiable) is turned on via a momentary push button switch. That switch creates a negative pulse which turns on the circuit, and then off again when the button is pushed again. What I want to do is enable the circuit to be turned on via a SPST switch. This means I need a circuit that will generate a negative pulse (or a positive pulse sent through an inverter) whenever the slide switch turns on and off. This timing diagram below may or may not make it clearer:SPST switch: --------------------------------------------- | | ------- -----------------I need ??? ------- -------------------------------------- ----------- | | | | ------ ------OEM ckt. -------------------------------------------- | | ------- -----------------Any ideas are appreciated.Thanks,Jonathan B.
