2-Pin Miniature Tactile Push Button Switch – Compact PCB Mount Momentary Micro Switch for Smart Devices, Wearables, and Consumer Electronics (Pack of 3)

Product Description The 2-Pin Miniature Tactile Switch is an ultra-compact, momentary signaling component designed for high-density electronic assemblies. Unlike standard 4-pin tactile switches, this 2-pin version is specifically engineered to save precious PCB real estate while providing the same reliable "Push-to-ON" functionality. It is widely used in modern smart devices, remote controls, and automotive interiors where space is at a premium. For Robogears Pvt Ltd, these switches are excellent for custom control interfaces and reset buttons on compact robotic controller boards.

Key Highlights

• Ultra-Compact Footprint: The 2-pin design significantly reduces the board space required, allowing for more streamlined and miniaturized product designs.
