B3F-4000
Overview
The B3F-4000 is a 12mm x 12mm square tactile switch from Omron Electronics designed for top-actuated through-hole mounting. It features a standard 4.30mm actuator height and provides a positive tactile feedback with a 130g operating force. This SPST-NO momentary switch is rated for low-current logic level switching up to 50mA at 24VDC.
Why Choose This Part
The 12mm footprint provides a larger surface area compared to standard 6mm switches, making it easier for users to locate and actuate. Its 4-pin through-hole design ensures high mechanical stability on the PCB, preventing the switch from lifting or shearing under heavy use.
Applications
Key Specifications
Getting Started
When designing the PCB layout, ensure the four pins are correctly mapped to the SPST-NO circuit, as the pins are internally connected in pairs. Standard soldering profiles for through-hole components apply, but care should be taken not to exceed the 70C ambient operating temperature during long-term use.
