I'm really struggling to find a simple circuit that'll give me a pulse (~1s) when switching the circuit on. The latching switch can't be changed and already controls other circuits, and the new module/controller requires a short pulse to turn on, but will reset if the on control input stays on for more than 10s.
Edit to add more info - Voltage when latching switch is on is 12V and 0V when off, there can be a constant 12V feed if needed to power circuitry but this'd just be pulled from the back of the switch. The new module requires a ~1s high (12v) pulse to tell it to turn on. Much less than that and it misses the on command sometimes.
I'll see if I can get a schematic to upload later as can't at the moment
Edit to add more info: pulse current - no more than 50mA. The reset time could be as low as ~200ms in theory but if it's a limitation ~1s would be acceptable
I'm not 100% sure but I believe that as long as the pulse is at least 9v it should work
