Hi guys,
I am at a complete loss. I have googled Latching transistor circuits and have only found diagrams using 12v Positive triggers, not a ground trigger. I am looking to build a latching circuit using NPN PNP transistors when pulsed by a N.O. switch to Ground.
Requirements:
Has to work with 12v DC to be used in my car.
Circuit Latches when pulse to ground by N.O. switch. Unlatched when SAME N.O. switch is pressed to ground.
Output from transistors need to offer Full Ground when active. Output will activate an 'On Board' 12v SPST Relay And send a Ground signal to illuminate a 12v Lamp 'OFF board'.
No reset switch needed or will be used.
Would like to have LED on board to light when circuit when circuit is active/Latched.
I'm not looking for someone to the work for me. Hoping Someone here can point me in the right direction for answers or send a link that have answers. Doesn't even have use NPN PNP transistors. That just what I am thinking need to be used.
Any feedback will be great and appreciated.
