Hi
I need to build a time delay circuit that when the bilge float switch opens (opens the circuit) there will be a time delay from the pump turning off . The reason I need this is to stop the constant on/off cycle of a bilge pump turning on and off with the float switch bobbing up and down.
The pump is 3 amps and 12 volts. I am working on a ball park figure of a 10 second delay from when the float switches and the pump stops. I pucrchased a 100K pot and a 100uf cap right T=R*C so 100,000*.000100 = 10Sec right ? the problem is I am not sure what to put where? Does this all go in series or parrell with the power source? Where does the pump hot 12V side go?
Any help would ne great
Thanks
