Typical 3PDT latching mechanical switches are noisy, hard to press, and prone to mechanical failure after repeated use. A controller board with a relay is a great alternative, and provides some other really great options you couldn't otherwise do.
This tiny and featureful relay bypass board can do a LOT.
Already have one or want to learn more? You can visit the GitHub project page to find the schematic, code, gerber files, etc. Or download the Relay Bypass Build Documentation here.
