Active17,072 in stock
Overview
The B3F-3122 is a right-angle, side-actuated tactile switch designed for through-hole mounting. It features a SPST-NO contact configuration and provides a crisp tactile feedback with an operating force of 1.47N (150gf).
Why Choose This Part
The right-angle design allows for side-access actuation without requiring a separate vertical PCB. Its silver-plated contacts ensure reliable switching at low currents, rated for up to 50mA at 24VDC.
Applications
Edge-Mounted User Interfaces
Ideal for reset buttons or user input on the side of handheld devices or enclosure walls.
Industrial Control Panels
Used as a high-reliability momentary switch for triggering functions in automation equipment.
Consumer Electronics
Suitable for power or volume buttons in devices requiring a 90-degree actuation relative to the PCB.

Getting Started
When designing the PCB layout, ensure the 7.30mm x 6.25mm footprint accounts for the side-actuated plunger extension of 3.85mm. Manual or wave soldering can be used for the through-hole PC pins, adhering to standard thermal profiles to protect the internal dome mechanism.
