Miniature SPDT Slide Switch 3-Pin — Breadboard & PCB Compatible (5-Pack)

Miniature SPDT Slide Switch — 3-Pin, Breadboard & PCB Compatible (5-Pack)

These compact SPDT (Single Pole Double Throw) slide switches are one of the most versatile and commonly used switches in electronics prototyping. With three pins (Common, Position A, Position B), a single slide switch can route a signal to one of two destinations, connect or disconnect power, or select between two operating modes. The miniature footprint fits directly into a solderless breadboard or standard 2.54mm PCB pads, making them ideal for Arduino projects, portable devices, and any circuit that needs a reliable latching toggle.
