So I'm getting ready to wire up my RIMS system, and my current plan is to have two switches.
Switch one provides power to the pump, and power to switch 2. Switch 2 turns on the heater element circuit.
Both are just "On-Off" Toggle switches.
I'd love to have it so when I power cycled the pump, there would be a component (relay?) that would kill power to Switch 2 (which runs the heater) until I pressed a "reset" button or something.
So, process would be:
1) Turn on Switch 1, pump starts.
2) Depress "Reset" button, energizing Switch 2
3) Turn on Switch 2, heater starts.
This way, even if I accidentally leave switch 2 "On", and next time I brew I turn on Switch 1 and work on ensuring I have flow through the RIMS, the heater can't switch on, since the heater circuit would have reset to Normally Open upon power cycling the pump.
Make sense? So I need something that is NO until you give it a momentary jolt from a reset switch, and then it says Closed until it loses power, at which point it opens again. What would that component be called?
(Only way I can figure on it is to have some kind of fancy capacitor/timer/latching relay setup to do this, but that seems excessive).
Thanks all you EEs out there!
