What are the key specifications of W4B003210?

The part is rated for 50 mA at 12 VDC, has contact resistance of 100 mΩ maximum, insulation resistance of at least 100 MΩ, dielectric strength of at least 250 VAC for 1 minute, and travel of 0.20 ±0.10 mm. Its code indicates 260 gf force and 100,000-cycle life.

What should engineers review before using W4B003210?

Check the recommended PCB land pattern, switch height, actuator clearance, and required actuation force. The PDF says 0.75 mm high, but the supplied source description calls it a 0.8 mm switch, so the mechanical dimension should be confirmed.

What is the pinout of W4B003210?

Use the W4B003210 datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about W4B003210 pinout to locate pins, power rails, and interface signals before layout.

AI summary

W4B003210 is a compact 4-pin SMD tactile switch from SAMZO's W-3×3 mm series. Its ordering code indicates the 260 gf operating-force and 100,000-cycle version.

Best for

Low-profile PCB user inputs
Compact consumer controls
Momentary normally-open switching

Avoid if

Applications requiring a force other than 260 gf
Designs with unverified 0.75 mm versus 0.8 mm height tolerance
High-current switching

Check before use

Verify the PCB footprint against the drawing
Confirm 260 gf tactile force is acceptable
Confirm mechanical height with the supplier
Validate endurance requirements against 100,000 cycles
