Proctor-Silex coffee machine replacement switch bracket

thingiverse

I replaced the faulty Proctor-Silex 12-cup coffee machine switch with a new one, as the old switch kept getting corroded and was no longer reliable. To ensure a secure connection, I needed a bracket that would hold the new switch in place on the original plastic assembly posts where the screws fasten into. Unfortunately, these security screws are "spanner slotted," making it difficult to find the right fit. If you plan to do this repair, be aware that you can reuse the neon indicator bulb and 1Mohm resistor from the old switch by pulling them out and attaching them to your new switch. The bracket I designed has a hole next to the main switch hole for the bulb, allowing you to connect it easily. When wiring the switch, make sure to break or make the hot line to the heating element, and run the neon bulb and resistor in series between the switched-power and neutral. It's highly recommended to use shrinkwrap tubing or a switch with reusable spade connectors to secure the connections. Keep in mind that you may need to edit the "arm jaw width," "arm length," and "switch hole diameter" values in the OpenSCAD file to get it to fit your replacement switch perfectly.
