Hot-Selling Tact Switch For Smart Remote Controls

Compact, reliable SMT tactile switches optimized for smart TV/AC/IoT remotes. Deliver crisp but quiet feedback, long life, and stable low‑current performance. Available in popular 3×6, 4.5×4.5, and 6×6 footprints with multiple heights and operating forces to fit slim housings and diverse key layouts.

Key Advantages

• Clean, low-noise click for living-room use
• Long mechanical life (up to 1,000,000 cycles, model-dependent)
• Low-current, gold-plated options for signal-level switching
• Slim heights for ultrathin remotes; side-actuated variants for edge buttons
• Strong ESD robustness for exposed keys
• SMT, tape & reel supply for high-volume assembly

Typical Applications

• Smart TV/streaming box remotes
• Set-top box and soundbar controllers
• AC/fan/projector remotes
• Voice-assistant and universal remotes
• Pairing/reset/menu navigation keys

Popular Footprints (remote-friendly)

• 3×6 mm SMD: 3.5×6.0 mm body; heights 2.5–7.0 mm; forces 160/200/260/320 gf
• 4.5×4.5 mm low-profile: heights 1.5–2.2 mm; forces 120/180/250 gf
• 6×6 mm SMD: heights 4.3–7.3 mm; forces 160–320 gf; ideal for power/pairing keys
• Side-actuated 4.2×3.2 mm: height ~1.7–2.0 mm for rocker/edge keys

Key Specifications (typical ranges)

• Travel: ~0.20–0.35 mm; crisp tactile dome
• Operating force: 120–320 gf (model-dependent)
• Electrical rating: 12 VDC, 50 mA max (signal level)
• Contact resistance: ≤100 mΩ initial
• Insulation resistance: ≥100 MΩ at 100 VDC
• Dielectric strength: ~250 VAC, 1 min

• Terminals/plating: Ni underlayer; Au for low current/corrosive sweat; Ag for general use
• Options: open-frame (IP40) or splash-resistant washable designs

Assembly & Design Notes

• Reflow: peak ~245°C; 60–90 s above 217°C; follow pad layout and keep-out under actuator
• Use plungers/keycaps to avoid side-load and excessive over-travel
• For post-reflow cleaning or conformal coating, choose sealed/washable variants
• Plan ESD return paths and shielding for exposed keys
• Coordinate silicone keymat hardness and plunger geometry with chosen force/travel

Quality & Compliance

• RoHS and REACH compliant; halogen-free options
• Housings available with UL94 V-0 materials (model-dependent)
• Reliability validation: thermal cycling, humidity, vibration/shock, ESD, salt/sweat exposure
• Lot traceability and outgoing inspection

Supply & Packaging

• Tape & reel: typically 3,000–5,000 pcs/reel (8/12 mm tape)
• Samples via cut tape or trays
• Lead time: stock variants ship quickly; standard builds 3–6 weeks

Customization & Selection Tips

• Force: 160–200 gf for general keys; 250–320 gf for power or anti‑misclick
• Height: pick lowest profile compatible with key travel and enclosure
• Plating: gold for low current or sweat-prone use; silver for cost-sensitive general use
• Actuation: top for keymat buttons; side for edge/rocker designs
• Acoustic: select quiet-click domes for premium living-room feel

Ordering Information (configurable)

• Format: TS-RC-[Size]-[Height]-[Force]-[Plating]-[Act]-[Seal]-[Pack]
