2P Waterproof Tactile Switch

Product Structure and Materials of 8*8MM Waterproof Tactile Switch 

The product structure of this 8×8 waterproof tactile switch comprises: keypad, positioning bracket, spring contact, base, pin terminals, and protective casing body.

This 4P 8×8mm waterproof tact switch with a protective cover features a cover design that is key to enhancing reliability and protection capabilities.

The function of the protective cover for waterproof tactile switches

1. Enhanced Waterproofing and Dustproofing (Core FunctioThe protective sleeve is made of one-piece molded silicone/rubber material, forming

 a dual-seal structure with the switch body and button cap. This elevates the protection rating from basic water resistance to IP67, enabling it to 

withstand harsh conditions such as high-pressure water jets and short-term immersion.

The sleeve's enveloping design completely blocks dust, oil, and fine particles from entering the switch interior, preventing contact short circuits 

or reed switch jamming. This makes it particularly suitable for dusty and humid environments like outdoor equipment and automotive chassis.

2. Mechanical Protection and Impact Resistance

The sleeve's elastic material absorbs impact forces during actuation, cushioning external forces from directly striking internal springs and contacts. 

This reduces mechanical wear, extending the switch's actuation lifespan from the standard 500,000 cycles to over 1,000,000 cycles.

The casing blocks external contaminants (e.g., metal shavings, liquid splashes) from corroding pins and solder joints, preventing pin bending and 

joint cracking while enhancing post-soldering structural integrity.

3. Electrical Insulation and Safety

The insulating material of the sleeve isolates the switch's metal pins from the external metal housing, preventing short-circuit risks from accidental 

contact. This significantly enhances circuit safety, particularly in high-voltage applications like automotive electronics and industrial control systems.

The sleeve's encapsulating structure also reduces electromagnetic interference (EMI) effects on switch signals, improving the stability of electrical 

signal transmission.

4. Installation and Positioning Assistance

The protrusions and slots in the housing precisely align with PCB mounting holes, enabling rapid switch positioning and preventing misalignment 

during soldering to boost production efficiency.

Some housings feature anti-slip textures, facilitating insertion and removal during assembly and maintenance while reducing human error
