B3F 6x6mm Tactile Switch 100gf

Omron B3F 系列 Introduced circa 1990

Omron B3F tactile switch — the other ubiquitous 6x6mm PCB button.

常见应用

Alongside Alps SKQG, the Omron B3F is the most commonly specified 6x6mm tactile switch in electronics. Found in keyboards, game controllers, test equipment, and embedded systems. The B3F-1000 is the basic variant — thousands of configurations exist for stem height, force, and termination.

安装快速参考

Panel cutout: 22mm. Insert from the front of the panel, secure with mounting nut from behind (tighten to 2-3 Nm).

Contact block: Snap or screw the contact block onto the rear of the button body. Ensure the contact block orientation matches the wiring diagram — NO terminals are usually marked.

Wiring: Use 0.5-2.5mm² stranded wire with ferrules. Tighten screw terminals to 0.8 Nm. Test the button function before energizing the circuit.

故障排除

Button doesn't respond when pressed

Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.

Works intermittently

Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.

Button feels mushy or doesn't click

The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.
