SMT Top Actuated 3×4 Tact Switch
Part Number: KAN3242A-0253B0101
The KAN3242A-0253B0101 is a 4.2 × 3.2 × 2.5 mm surface-mount top-actuated tact switch rated to DC 16 V with a high 49 N stop strength. It surface-mounts to a PCB, gives a light press at 160 gf, and is rated for 100,000 operating cycles across a wide –40 °C to +85 °C range. ISO 9001 and IATF 16949 certified, RoHS compliant, and shipped factory-direct from our Shenzhen, Wenzhou and Hubei plants.
Key Features
- Rated to DC 16 V for higher-voltage signal lines
- High 49 N stop strength for firm press limits
- ≥500 MΩ insulation resistance for clean switching
- Compact 4.2 × 3.2 mm footprint, 2.5 mm height
- Wide –40 °C to +85 °C operating range, 100,000-cycle life
