Tiny tactile switches tackle wireless

The B3U tactile switches feature a footprint of 3.0 2.5mm, and are 1.2mm high, whether in top or side actuating form. Both versions offer a sealed construction for use in dust-laden environments.

The switches, crafted by Omron, are suitable for designs in wireless headsets, mobile phones, portable instruments, keyless entry systems, and other applications where size is a critical factor.

The side and top push actuation versions of the B3U are available with a ground terminal to avoid static build-up, and a boss to locate the switch on the board during assembly. They are designed to withstand reflow-soldering processes for surface-mount manufacturing. The switches come in tape-andreel packaging, which is ideal for high-volume production.
