Description
Quick-and-dirty little circuit to switch a garbage disposal from a low-voltage momentary button. PCB fits into junction box. For supporting files, refer to https://github.com/gutschke/garbagedisposal
I couldn't find all the parts that I wanted from LCSC. For now, I linked to DigiKey parts. If you have suggestions for suitable substitute parts from LCSC, please let me know.
I made reasonable accomodations for the 1HP motor that I happen to use. If your motor has different in-rush or stall currents, you might have to add by-pass wires for the high-current paths on the PCB. I also recommend that you order 2oz copper boards. Use your best judgement and don't just blindly trust me. I disclaim all warranty.
