3×4×2.5mm SMD Tactile Push Button Switch

The 3×4×2.5mm SMD Tactile Push Button Switch is a high-quality, low-profile momentary switch designed for modern compact electronic circuits. Its small footprint makes it perfect for space-constrained PCB designs such as IoT devices, development boards, and embedded systems.

This switch features a white actuator cap for a clean and professional look, especially useful in visible UI designs. With a 4-pin SMD configuration, it ensures strong PCB mounting and reliable performance.

When pressed, the switch temporarily closes the circuit (momentary action), making it suitable for user input functions like reset, mode selection, and navigation controls.
