Fingertip Switch WK02

WK02​ is a high-performance fingertip switch specifically designed for critical applications across various industries, including broadcasting equipment, security systems, automation technology, medical devices, and optical instruments. It combines durability and precision, utilizing a Hall-effect sensor to ensure reliable operation in demanding environments.

Featuring an ​operating angle of ±24°​ and a ​5V DC power supply, the WK02 delivers precise tactile feedback while maintaining low power consumption (12mA). Its ​5 million-cycle mechanical lifespan​ makes it ideal for high-frequency operations in ​broadcast systems, industrial automation, medical devices, security controls, and optical instrumentation. The ​Hall-effect sensor​ eliminates mechanical wear, providing bounce-free switching and resistance to dust, moisture, and vibration.

Available in both ​spring-return (momentary) and 3-position detent (latching) variants, the WK02 offers flexibility for diverse control needs. With an ​extended operating temperature range (-40°C to +70°C)​, it performs reliably in harsh indoor and outdoor settings.

Compact yet robust, the WK02 is designed for ​easy panel integration​ and can be customized for specialized applications. Whether used in surgical robotics, CNC machinery, or broadcast switchers, it ensures ​long-term accuracy and durability​ where conventional switches would fail.
