Tact Switch Button

The working principle of the light touch switch with bracket is based on its internal spring plate and contact structure. When the external force acts on the button of the switch, the spring plate will be deformed, so that the contact between the contact or disconnect. This design allows the switch to react quickly when slightly pressed to achieve on-off control of the circuit.

Tact Switch with Bracket's Feature

1. Actuation Force: Typically ranges from 160gf to 250gf (1.57N to 2.45N), providing optimal tactile feedback for user interaction. High-end variants offer adjustable actuation forces down to 50gf (0.49N) for specialized applications.

2. Travel Distance: Standard models feature 0.25mm pre-travel and 0.1mm over-travel, with total travel distances between 0.3mm to 0.7mm. Ultra-low profile designs achieve 0.15mm total travel for space-constrained PCBs.

3. Electrical Life: Rated for 100,000 to 500,000 cycles (IEC 60112 compliant) with contact resistance below 50mΩ. Gold-plated contacts extend lifespan to 1,000,000 cycles in low-current (≤100mA) applications.

4. Environmental Resistance: IP67-rated switches withstand operating temperatures from -40°C to +85°C. Dielectric strength reaches 250VAC for 1 minute (UL 61058-1 standard).

5. Package Dimensions: Surface-mount (SMD) types measure as small as 3.5×2.8×0.9mm (L×W×H), while through-hole versions maintain 6×6×5mm footprints with 0.5mm terminal pitch tolerance.

6. Electrical Ratings: Standard models handle 12VDC at 50mA, with high-current versions supporting 24VDC at 200mA. Insulation resistance exceeds 100MΩ at 500VDC (per IEC 60664-1).
