Overview

The B3U-1000P is an ultra-small, surface-mount tactile switch designed by Omron Electronics for high-density PCB layouts. It features a top-actuated mechanism with a compact 2.5mm by 3.0mm footprint and a low profile of 1.2mm, making it ideal for portable devices where internal space is at a premium. This model is the standard version without a ground terminal or boss for alignment, prioritizing the smallest possible mounting area.

Why Choose This Part

The primary advantage of the B3U-1000P is its industry-leading small size, which allows for extremely tight component spacing on the PCB. It offers a distinct tactile click despite its miniaturization, ensuring user feedback. The surface-mount design is compatible with automated pick-and-place equipment and standard reflow soldering processes.
