Product Description
Compact, reliable, and highly tactile, this mini push button switch is designed for user interfaces in Bluetooth-enabled devices and control systems. Ideal for functions such as pairing, power, reset, play/pause, or mode selection, it delivers crisp feedback with long operational life. Available in both SMD and through-hole versions to suit a wide range of PCB layouts and manufacturing processes.
Key Features
- Momentary action, SPST-NO (single pole single throw, normally open)
- Distinct tactile feedback for confident actuation
- Low profile options for space-constrained designs
- Multiple actuation forces (light to firm) to match your user experience
- Long life: up to 1,000,000 cycles depending on model
- Stable electrical performance with low contact resistance
- SMD (tape-and-reel) and THT (bulk/tray) packaging options
- RoHS and REACH compliant, halogen-free
- Optional dust/water-resistant versions for harsher environments
Typical Applications
- Bluetooth speakers and soundbars (play/pause, pairing, volume)
- Headphones and earbuds charging cases
- BLE remotes and smart controllers
- IoT gateways and hubs (reset/config)
- Smart home panels and wall switches
- Wearables and portable medical devices
- Development boards and modules with user input buttons
