Buttons and switches

Separate simple momentary pushbuttons from rotary-control breakouts and potentiometer wiper parts before treating them as swappable user inputs.

digital contact

Use for simple press-to-close user input. Match contact rating, mounting, cap size and whether an LED circuit is present.

stepped resistance

Use when the design needs a 10-step rotary value, not a normal on/off button. Requires the separate rotary switch and selected resistor values.

mechanical actuator

Use with compatible SoftPot, ThinPot or HotPot sensors where force, thread and body length match the mechanical design.

Can I swap these?

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.

Momentary Pushbutton Switch - 12mm Square

Straightforward 12 mm momentary pushbutton for PCB or breadboard-style user input. Good fit when the design needs a simple press-to-close control.

Momentary Pushbutton Switch

Illuminated momentary pushbutton. Functionally button-like, but the LED circuit, voltage rating and mounting details must be matched.

SparkFun Rotary Switch Potentiometer Breakout

Rotary-control accessory board for building a 10-step potentiometer around a separate rotary switch. Not a pushbutton substitute.

Potentiometer Wiper/Plunger - 14mm

Mechanical wiper/plunger accessory for SoftPot, ThinPot and HotPot sensors. Not an electrical button or switch.
