Buttons & switches
Momentary pushbuttons, illuminated buttons, reed switches, arcade buttons, slide switches and rocker switches in one group — plus a handful of rotary-switch breakouts and potentiometer actuators that look like controls but behave differently.
Most parts here are simple contacts: press or release, open or closed. A few outliers — rotary switch potentiometer breakouts, NeoPixel potentiometers, wiper plungers — carry separate wiring requirements worth checking before you order.
- Momentary pushbuttons are direct contacts; illuminated versions also need LED wiring and voltage checks for the indicator circuit.
- Reed switches close in a magnetic field with no external power; their NC/NO state and current rating matter more than physical size.
- The SparkFun Rotary Switch Potentiometer Breakout and the Adafruit NeoPot are accessory boards, not drop-in button replacements — the rotary switch breakout rides a 10-position rotary switch, the NeoPot pairs a clear-shaft pot with a NeoPixel RGB LED.
- The Potentiometer Wiper/Plunger is a mechanical actuator for SoftPot and ThinPot ribbon sensors, not a contact switch at all.

Pick the board you have - we'll show what we know about swapping it.
Known swap options (1)
General board checks (5)
- Confirm whether the design needs momentary contact, latching action, rotary position, analog resistance or a mechanical actuator.
- Match contact rating, LED voltage, pull-up or divider assumptions, and whether firmware expects digital or analog input.
- Compare footprint, panel mounting, breadboard spacing, plunger thread, body length, cap size and tactile feel.
- Check whether the listing is a complete switch/control or an accessory that needs another part.
- Use the vendor product page, guide or datasheet as the final source before buying or swapping.
