Product Description

A compact 6×6 mm surface-mount tactile switch designed for makers, educators, and rapid prototyping. It delivers a crisp, consistent click, supports standard lead-free reflow, and fits tight layouts on hobby and production PCBs alike. Ideal for Arduino shields, Raspberry Pi HATs, keypad modules, wearables, and custom controllers.

Key highlights

  • 6×6 mm top-actuated SMT package; slim profiles for dense boards
  • Crisp tactile feedback with smooth travel for confident presses
  • Maker-friendly: hand reworkable, available in cut-tape for small builds
  • Reliable performance at low voltage/current logic levels
  • Tape-and-reel for pick-and-place; vacuum-pickable actuator
  • RoHS/REACH compliant; halogen-free options

Typical applications

  • DIY kits, STEM learning boards, dev boards and shields
  • Macro pads, remote buttons, encoder confirm keys
  • Portable gadgets, wearables, sensor nodes, IoT remotes
  • Robot/drone UIs, 3D-printer panels, LED controllers

Electrical

  • Rating: 12 VDC, 50 mA (max)
  • Contact resistance: ≤100 mΩ (initial)
  • Insulation resistance: ≥100 MΩ at 100 VDC
  • Dielectric strength: 250 VAC for 1 minute
  • Bounce time: ≤10 ms (typical)

Mechanical

  • Operating force options: 160 gf, 260 gf, 320 gf (±20%)
  • Total travel: 0.25 ± 0.10 mm
  • Life: up to 500,000 cycles (force/height dependent)
  • Operating temperature: -20 to +70°C
  • Storage temperature: -30 to +85°C

Materials

  • Actuator/plunger: POM
  • Cover: stainless steel (SUS)
  • Base: high-temperature thermoplastic (UL94V-0)
  • Terminals/contacts: copper alloy; standard Ag plating, optional Au over Ni for low-level signals or corrosive environments

Dimensions and PCB Footprint

  • Body size: 6.0 × 6.0 mm (top-actuated)
  • Standard actuator heights: 2.5 / 3.1 / 4.3 / 5.0 / 7.0 / 9.5 mm
  • Pad layout: 4 SMT pads in an approx. 6.5 × 4.5 mm rectangle (typical)
  • Recommended land pattern: solder-mask defined pads, paste aperture ~1:1 with pad; keep-out around metal cover to avoid interference
  • Note: Full dimensional drawing and recommended footprint available on request

Soldering and Assembly

  • Reflow (Pb-free): peak 245–250°C; time above 217°C 60–90 s; ≤2 cycles
  • Hand rework: 350°C tip, ≤3 s per pad; or hot air 280–300°C with thermal shielding
  • Cleaning: non-sealed structure; avoid aqueous/ultrasonic wash. Wipe or vapor-solvent cleaning only.
  • Handling: compatible with vacuum nozzles; avoid side-load on the actuator during placement

Quality and Compliance

  • RoHS and REACH compliant; lead-free
  • Housing UL94V-0
  • Manufactured under ISO 9001 quality system
  • AQL and lot traceability available

Customization and Accessories

  • Force tuning: 100–400 gf ranges
  • Heights: custom stems and extended actuators
  • Contact plating: silver (standard) or gold over nickel (for very low current or high humidity)
  • Caps: low/high profile, soft-touch, color-matched (Pantone), opaque or translucent for LED indication
  • Semi-sealed variant for light splash resistance (on request)
  • Packaging: tape & reel (EIA-481), cut-tape for prototyping, or small trays

Packaging, MOQs, Lead Time, Samples

  • Tape & reel: 8 mm tape; typical 1,500–3,000 pcs/reel (height-dependent)
  • Cut-tape: maker-friendly quantities (e.g., 20–200 pcs)
  • Lead time: 7–12 business days standard; customs by agreement
  • Samples: free engineering samples ship in 48–72 hours

Engineering Resources

  • 3D CAD: STEP/IGES for each actuator height
  • PCB libraries: Altium, KiCad, and Eagle footprints/symbols
  • Datasheet, test reports (life, plating corrosion), compliance certificates

Design Tips For DIY Builds

  • Firmware debounce: 5–10 ms typical; adjust for user feel
  • Choose 160 gf for light-touch UIs; 260–320 gf for anti-mistrigger keys
  • Use gold plating when switching <1 mA or <5 V for long-term reliability
  • Provide a mechanical keep-out above the cap to prevent chassis rub
