Product Description
A compact, board-mount momentary push switch engineered for sensor modules that require a longer actuation stroke and clear haptic feedback.The extended travel improves ergonomics, reduces accidental triggers, and accommodates mechanical tolerances between the switch and the external actuator or enclosure.Available in SMD and through-hole variants with multiple operating force options and high-temperature materials suitable for automated assembly.
Key features
- Long actuation travel: 1.8–3.0 mm for confident, deliberate presses
- Crisp, audible/tactile feedback with stable over-travel region
- Multiple operating forces: 160 / 230 / 320 / 450 gf to suit different UX needs
- High durability: up to 1,000,000 cycles (force-dependent)
- Compact footprint for dense sensor module layouts
- High-temperature housing for reflow; wave and hand solder compatible
- Optional extended actuator/cap and dust cover for improved interface
- Low contact bounce and consistent electrical performance
- ESD robustness and ground pin option (selected variants)
- RoHS, REACH compliant; halogen-free
Typical applications
- Environmental sensor modules: calibration, zeroing, mode select
- IoT nodes and BLE sensor beacons: pairing/reset
- Smart home detectors: test/hush buttons (smoke/CO, motion, leak)
- Industrial sensing: field service, diagnostics, teach-in
- Medical and wellness sensors: user input with gloved operation
- Automotive sensor nodes and harness modules: setup/service
- Metering and utility modules: tamper, test, configuration

Assembly and Soldering
- Reflow solder: compatible; peak 260 °C max, follow standard reflow profiles
- Wave solder: compatible for through-hole variants
- Hand solder: 350 °C max, ≤3 s per pin; avoid mechanical stress during solder
- Cleaning: Solvent-compatible; avoid ultrasonic cleaning on sealed variants unless validated
Reliability and Compliance
- Environmental: RoHS and REACH compliant; halogen-free
- Humidity test: 40 °C, 90–95% RH (96 h), typical performance retained
- Vibration/shock: Suitable for mobile and industrial modules; validate in-assembly
- Optional sealing: Dust cover available; consult for IP performance options
Design Notes
- Long travel increases tolerance to mechanical stack-up and reduces false actuations in sensor housings.
- Select operating force based on enclosure stiffness and actuator leverage.
- Use ground pin and proper PCB layout for improved ESD immunity.
- For gloved or blind operation, choose extended actuator with higher force for clear feedback.
Ordering Guidance
- Define mounting (SMD or TH), footprint, height/actuator style, operating force, terminal finish (Sn or Au), and packaging.
- Custom actuator caps, colors, and force curves are available upon request.
