Hi all,
Alright, the circuit uses a vibration switch to trigger a 555 timer which runs for about 3.5 minutes. The output of the 555 drives a 5VDC 1A relay to a load. I know that the 555 timer cuts off, but the relay does not, retriggers the 555 output I think. I have put the required 1N4004 and 1N4148 diodes as seen in other circuits, but this does not address the problem.
Any ideas on what else I can do or perhaps some ideas to improve the circuit? I do need to use the 555 and would prefer not to swap to a different IC.
Thanks.
I have attached the circuit below.
