Tongda Wire Electric IP67 Waterproof Micro Switch Introduction

FSK-18 adheres to the design philosophy of 'Upgraded Protection, Stable Performance,' and is tailor-made for complex environments such as humidity, dust, and outdoor conditions. The product features an integrated sealed structure, with a casing made of high-strength flame-retardant material, paired with precise waterproof sealing rings to achieve an IP67 protection rating (no leakage after 30 minutes of immersion in 1-meter-deep water), effectively resisting moisture, dust, and oil corrosion. Its medium size balances installation flexibility and operational convenience, supporting various mounting methods such as panel installation and PCB soldering, making it suitable for a wide range of device control panels and confined assembly spaces. The operation travel is 0.6-1.5mm, with clear pressing feedback, and the operating force can be custom-adjusted between 1.0-5.0N to meet the operational needs of different scenarios.

Extended lifespan design: Mechanical lifespan exceeds 100,000 cycles, electrical lifespan reaches 50,000 cycles. Based on 30 high-frequency operations per day, it can be reliably used for over 9 years, far surpassing consumer-grade product standards. The contacts are made of silver alloy, with an initial contact resistance of ≤50mΩ, excellent arc extinguishing performance, effectively reducing arc erosion and ensuring stable circuit switching.

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.
