KSU213WLFG is a micro mini surface mount detect switch featuring momentary action with SPST normally open contact configuration and gullwing terminals optimized for SMT assembly. The switch incorporates a metal actuator with a low switching force of 0.7 ± 0.5 N, mechanical travel of 1.5 ± 0.2 mm, and travel to make of 0.65 mm with a tolerance of -0.45/+0.25 mm, delivering reliable tactile feedback with a bounce time of =3 ms. Electrically, it supports a maximum voltage of 32 VDC, maximum power of 0.2 VA (gold contact variant), contact resistance of =100 mO, and insulation resistance of 10? O at 100 VDC, with an operating life of 100,000 cycles. The device operates across a wide temperature range of -40°C to +125°C and is RoHS compliant with lead-free reflow soldering compatibility, making it ideal for mobile phones, portable medical devices, audio devices, alarm devices, payment terminals, and smart meters.
