Quick-Action Tact Switch 2x3 For Industrial Control

• Ultra-compact tact switch designed for industrial HMI and field devices. 2×3 mm footprint, short travel for fast actuation, crisp tactile feedback, supports high-temperature reflow and long-life operation.
• High-temperature materials and stable dome spring structure deliver consistent feel and contact reliability under vibration, temperature swings, and frequent use.

Key selling points

• Fast actuation, crisp tactile feel: short travel with clear detent reduces mis-operations and improves keying efficiency.
• Industrial-grade durability: up to 1,000,000 electrical cycles depending on operating force and conditions; ideal for high-frequency use.
• Wide temperature and environmental resilience: operating -40 to 85°C (optional -40 to 105°C). Optional top-sealed dust/water protection.
• Tiny footprint: 2×3 mm for high-density PCBs and slim panels.
• Flexible configurations: multiple operating forces, heights, terminal styles (SMD/TH), surface plating, and sealing levels.
• Mass-production friendly: SMT reflow compatible; tape-and-reel supply for automated pick-and-place.

Typical applications

Construction and materials

• Cover/body: high-temperature LCP or PA46 engineering plastic (reflow capable)
• Dome spring: stainless steel or phosphor bronze, silver or gold plated for reliable conductivity
• Terminals: copper alloy, tin plated (SMD or through-hole)
• Seal: silicone membrane for IP67 versions
• Optional surface treatments for anti-fingerprint/corrosion resistance in harsh environments

Dimensions and mounting

• Mounting styles: SMT (surface-mount) or TH (through-hole for higher mechanical robustness)
• Recommended land pattern: see datasheet or request PCB footprint library (Gerber/ECAD)
• Tape-and-reel supply: 7" or 13" reels with clear orientation marks; suitable for automated placement
• Compatible with keycaps, silicone keypads, or membrane panels for enhanced feel and sealing

Soldering and assembly guidelines

• Reflow soldering: peak ≤260°C for ≤10 s; preheat 150–180°C for 60–120 s; recommend ≤2 reflow cycles
• Hand soldering: 350°C, ≤3 s per pin; avoid pressing on the body or prolonged high heat
• Cleaning: non-sealed versions not recommended for immersion/ultrasonic cleaning; sealed versions allow limited cleaning; avoid aggressive solvents
• Mechanical assembly: avoid strong side loads and sustained high-pressure actuation; ensure even force transfer from panel mechanisms

Reliability and environmental tests (reference)

• Temperature cycling: -40 to 85°C passed typical cycling tests
• Vibration: 10–55 Hz, 1.5 mm amplitude, 2 hours without functional abnormality (typical)

FAQ

• Can it be actuated from the side? Recommend vertical actuation. For side presses, use a side-actuated design or add a guiding mechanism.
• How can we extend life? Choose a higher OF, optimize the force transfer area, minimize contamination and environmental stress, and implement proper debounce.
• Will the tactile feel change after reflow? Minor change is normal. Using high-temp materials and a correct reflow profile keeps variation within acceptable limits.
• Can it support waterproof front panels? Use the IP67 top-sealed version with a sealed panel or silicone keypad to achieve high overall protection.
