Waterproof Micro Switch Introduction

The FSK-18 is a fully sealed waterproof micro switch rated IP67. It delivers excellent protection against dust, splashing water and temporary immersion, ideal for humid and harsh working environments. Equipped with durable silver contacts, it features stable conductivity and long service life. Multiple certifications are available for global applications in home appliances, outdoor devices and automotive systems.

Many ordinary micro switches fail easily after exposure to water or splashes. The FSK-18 waterproof micro switch features IP67 full sealing design, effectively blocking water, moisture and dust. It will not short circuit or get stuck even in wet environments like washing machines and outdoor devices. With premium silver contacts, it maintains stable performance and greatly reduces replacement frequency.

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.
