Product Description:
The 8B series consists of ultra-compact surface-mount sealed push-button switches, which are highly integrated circuit control components designed specifically for compact electronic devices
Advantages:
1. Simple and Reliable Switching Function;
Offers momentary ON and momentary OFF functions to meet standard application needs with clear actuation.
2. Excellent Waterproof Performance;
The only opening is sealed with rubber, achieving IP67 certification to ensure stable and reliable operation in wet or water‑exposed environments.
3. Flexible SMT Terminal Options;
Provides MT terminals (straight‑lead SMT type) and standard MZ terminals to accommodate different surface‑mount process requirements.
4. High‑Temperature Material and High Current Rating;
The switch materials are rigorously tested to withstand standard reflow soldering temperatures; the silver‑terminal version offers a current rating up to 3A at 120VAC or 28VDC, balancing process compatibility with electrical performance.
Application:
Industrial automation control equipment, precision instruments and meters, telecommunications equipment, consumer electronics, medical devices, transportation equipment, etc.
