Tongda Wire Electric IP67 Waterproof Micro Switch Introduction

Relying on Yueqing Tongda's comprehensive quality management system, the FSK-18 undergoes 12 key inspections from raw material intake to finished product output, including waterproof sealing tests, high and low temperature aging tests, and durability pressing tests, with a factory pass rate maintained at 100%. Currently, the product has an annual production capacity of 300 million units, supports various contact forms such as SPDT / normally open / normally closed, and offers customized actuators like pin plungers, levers, and roller levers. The standard order lead time is 7-15 days, while urgent orders are shipped within 3 days of response.

Wide-range environmental adaptation: Operating temperature covers -25℃ to 105℃, tolerating extreme high and low temperatures; insulation resistance ≥100MΩ (DC500V), terminal withstand voltage 1500V AC, passes vibration testing (10-55Hz, amplitude 1.5mm), maintaining reliable performance in industrial vibrations, vehicle bumps, and other scenarios.

Certified by multiple international authorities such as UL, CUL, ENEC, VDE, and CQC, compliant with RoHS and REACH environmental directives, meeting IATF16949 automotive industry quality system requirements, and suitable for global market access standards.

Tongda Wire Electric IP67 Waterproof Micro Switch Principle：

The functioning of a waterproof micro switch is based on the external application of mechanical forces on the action reed through transmission components such as push pins, buttons, levers, and rollers. As the action reed moves towards a critical point, it generates instantaneous action, causing the moving contact at the end of the reed to quickly connect or disconnect from the fixed contact.
Upon removing the force acting on the transmission element, the action reed produces a reverse acting force. As the transmission element undergoes a reverse stroke, it reaches the critical point of the reed, and the reverse action is completed instantaneously. The small contact distance, short travel, small pressure, and fast switching speed make the waterproof micro switch a reliable and efficient component. Additionally, the moving speed of the contact is independent of the speed of the transmission element.
