SparkFun describes COM-09190 as a breadboard-friendly 12 mm square momentary pushbutton with a large button head and tactile click.
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.
SparkFun Rotary Switch Potentiometer Breakout visual previewSparkFun 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 visual previewPotentiometer Wiper/Plunger - 14mm
Mechanical wiper/plunger accessory for SoftPot, ThinPot and HotPot sensors. Not an electrical button or switch.
Momentary Pushbutton Switch visual previewMomentary Pushbutton Switch
Illuminated momentary pushbutton. Functionally button-like, but the LED circuit, voltage rating and mounting details must be matched.
