Product Description
A compact, precision-engineered tactile switch optimized for Bluetooth interface controls such as pairing, reset, and multifunction buttons. Designed for wearables, audio devices, and IoT endpoints, it delivers a crisp, consistent click, low profile for tight spaces, and long mechanical life under frequent use. Available in multiple actuation forces and heights, with optional sealing for sweat and dust protection.
Key Features
- Compact SMD footprint for space-constrained designs
- Low profile options (down to 0.8 mm height) for slim enclosures
- Consistent tactile feel with selectable actuation forces (light, medium, firm)
- Crisp, low-bounce contact for reliable detection
- Long mechanical life up to 1,000,000 cycles (model dependent)
- Gold-over-nickel contacts for superior corrosion resistance
- Optional IP67 sealed variants for wearables and outdoor devices
- Reflow-compatible packaging (tape-and-reel)
- RoHS and REACH compliant; halogen-free materials
- Broad operating temperature range for consumer and industrial environments
Typical Applications
- Bluetooth pairing/Reset buttons in earbuds and charging cases
- Smartwatches and fitness trackers
- Portable Bluetooth speakers and soundbars
- Computer peripherals (mice, keyboards) pairing and DPI/function keys
- IoT hubs, remote controls, home automation panels
- Medical wearables and handheld instruments

Bluetooth Interface Design Notes
- Place the switch to minimize acoustic and mechanical coupling to microphones/speakers
- Maintain adequate clearance and ground strategy near the Bluetooth antenna to avoid detuning
- Implement firmware debouncing (10–20 ms typical) and long-press/short-press timing
- For wearables, select sealed variants and gold contacts to resist sweat and corrosion
Packaging
- Tape-and-reel for automated pick-and-place
- Standard reel quantities: 2,000 or 4,000 pcs (model dependent)
- Moisture-sensitive packaging for reflow processes
Accessories
- Low-profile caps and keytops
- Silicone boots for enhanced sealing
- Alignment fixtures for assembly
Notes
- Specifications are typical and may vary by model; confirm final values with the datasheet for the selected part number.
- Custom force, travel, and height configurations available for volume programs.
