Hi all,
I'm trying to use this discrete flip flop circuit with a momentary switch to switch a relay for true bypass of a guitar delay effect :
The only things not on the schematic are my 12V relay and a 1n4148 diode across the coil.
The weird thing is that when I close the switch, the relay closes momentarily and then opens again. Every time I press the button, it's a always this click on and off very quickly. I don't think this is an issue of debouncing because the relay always clicks twice only and this circuit is meant to provide de bouncing anyway...
Any suggestions about what could be causing this strange but consistent behaviour? Dodgy MOSFET perhaps?
Cheers
Rob
Ah - one final thing : a link to the source of the schematic :
