tactile push button 6x6 4pin SMT tact switch rubben button

A compact, surface-mount tactile push button switch designed for consumer electronics, wearables, IoT nodes, and compact control panels. This 6.0 × 6.0 mm, 4-pin tact switch provides crisp tactile feedback with low contact bounce and is available with a fitted silicone rubber button cap for improved ergonomics, dust resistance, and optional backlighting compatibility.

Key Features

• 6 × 6 mm SMD footprint with 4-pin stability
• Distinct tactile “click” with multiple actuation force options
• Low bounce for reliable signal integrity
• Long life up to 100k–500k cycles (model dependent)
• Optional silicone rubber button cap: improved grip, colors, and splash/dust resistance
• Low profile height options to suit enclosure constraints
• Rated up to 12 VDC, 50 mA; suitable for low-level signal switching
• High-temperature LCP base for Pb-free reflow soldering
• RoHS and REACH compliant; halogen-free options

• Cover: stainless steel snap dome for tactile feedback
• Base: high-temperature LCP, UL94 V‑0
• Contacts: Cu alloy with silver or gold plating (model dependent)
• Terminals: Cu alloy with matte tin plating over Ni
• Rubber button cap (optional): silicone, 50–60 Shore A; colors: black/gray/white/red (others on request); translucent options for backlighting

Environmental & Reliability

• Operating temperature: −40 to +85°C
• Storage temperature: −40 to +85°C (dry conditions)
• Humidity: ≤95% RH, non‑condensing
• Washability: standard type non‑washable; sealed/washable version available on request
• Dust/splash resistance: improved with silicone cap (not a substitute for full IP sealing)
• Compliance: RoHS, REACH; halogen‑free variants available

Soldering & Assembly

• Reflow soldering (Pb‑free):
  • Preheat 150–200°C for 60–120 s
  • Peak 245–260°C, ≤10 s above 255°C
  • Total time above 220°C: 60–90 s
• Reflow cycles: up to 2 cycles recommended; allow cooling between cycles
• Hand rework: 350°C max tip, ≤3 s per lead; avoid mechanical stress on actuator
• Cleaning: do not wash standard version; use sealed type if post‑solder cleaning is required
• Pick‑and‑place: available with optional pickup cap; remove cap after reflow if specified

Packaging

• Tape & reel per EIA‑481 for automated placement
• Reel sizes: 7 in (1,000–1,500 pcs) or 13 in (2,000–4,000 pcs), model dependent
• Moisture sensitivity: MSL 1 (typical); store in dry conditions

Usage Notes

• For matrix keypads, implement firmware debouncing (5–10 ms) despite low bounce
• Avoid side loads on the actuator; align external keytops or housings to press vertically
• Use rubber cap for better feel, dust mitigation, and to interface with external keycaps
• Do not exceed rated current/voltage; protect against inductive kick if driving coils

Customization Options

• Actuation force and height variants
• Gold‑plated contacts for improved low‑level switching
• Pre‑fitted silicone caps in custom colors, textures, or translucent types for LED backlighting
• Tape & reel orientation per customer PCB layout
• RoHS, REACH, and halogen‑free documentation pack
