Tactile Momentary Pushbutton Switch No Cap 12×12×7.3mm — 4-Pin Breadboard (5-Pack)

Tactile Momentary Pushbutton Switch — No Cap, 12×12×7.3mm, 4-Pin Breadboard (5-Pack)

These 12×12×7.3mm tactile momentary pushbutton switches are the capless version of the standard 12mm pushbutton — lower profile, smaller footprint, and ready to accept any snap-on cap color you choose. The 4-pin through-hole design fits directly into a solderless breadboard on standard 0.1" spacing, and the snap-action mechanism provides a satisfying audible click. Use these when you want to add your own cap, need a lower profile, or are mounting directly to a PCB. Pack of 5.
