Description

This is SMD 4 PIN Tact Switch with 4.2×3.2mm and 2.50mm height and three different actuator force 180gf/250gf/400gf options,Compact size,these momentary mini tact switch features an SMT gull wing design for surface mounting, ideal for general usage applications.For compatibility with production processes, the actuation surface is hard and flat.

1. Compact SMD 4-Pin Design, Space-Efficient Integration

Standard footprints (4.2×3.2mm) with ultra-low profile heights (1.5mm–5.0mm) for PCB layout optimization in miniaturized devices. The 4-pin gull-wing SMD configuration provides superior mechanical stability and balanced stress distribution during soldering, preventing board warpage and ensuring reliable contact in vibration-prone applications. Supports both horizontal and vertical mounting options to adapt to diverse space constraints.

2. Crisp Tactile Feedback, Precision Operation

200gf–350gf customizable actuation force with distinct click tactile and audible response for immediate user confirmation. Full travel distance (0.2mm–0.4mm) ensures accurate triggering while minimizing accidental presses. The precision internal spring mechanism maintains consistent feedback across 100,000+ mechanical cycles, ideal for frequent operation in consumer electronics and industrial controls.

3. Superior Electrical Performance, Stable Signal Transmission

Contact resistance ≤50mΩ (initial) for minimal signal loss and power consumption

Insulation resistance ≥100MΩ and dielectric strength AC500V (1 minute) for enhanced safety and noise immunity

Rated load: 50mA @ 12VDC, suitable for low-power circuit applications including IoT devices and sensor controls

Gold-plated contacts (optional) provide exceptional corrosion resistance and extended electrical life (10,000+ cycles)

TS42-3225
