The 4.8*4.8*0.75mm size makes the switch ideal for use in small electronic devices while maintaining good operability and aesthetics.
Waterproof Membrane of 4.8*4.8 Tact Switch
The surface of the switch is covered with a waterproof membrane, which effectively prevents water and moisture from entering the interior of the switch, thus protecting it from corrosion and damage.
The waterproof membrane is usually made of waterproof material, such as silicone, rubber, etc., with good elasticity and sealing performance.
Contact structure of 4.8*4.8 tap switch
The switch contains a contact structure inside. When the switch is pressed, the contact will close, thus conducting the circuit; when the switch is released, the contact will break, and the circuit will be disconnected.
Contacts are usually made of conductive materials, such as silver, copper, etc., with good conductivity and durability.
Waterproof performance of 4.8*4.8 touch switch
With a waterproof membrane, the switch has good waterproof performance and can withstand a certain degree of splashing water and humid environment.
The waterproof rating is usually IP67 or higher, which means it is completely protected from dust and can be immersed for a short period of time at a certain depth underwater (usually 1 meter) without damage.

FAQ
1. What is an IP67 momentary tactile switch?
An IP67 momentary tactile switch is a type of push-button switch designed for temporary (momentary) operation. It is rated IP67, meaning it is fully protected against dust and can withstand immersion in water up to 1 meter for 30 minutes.
2. What does "momentary" mean in tactile switches?
"Momentary" means the switch only activates while it is being pressed. Once the pressure is released, the switch returns to its default state. This is different from "latching" switches, which stay in the activated position until pressed again.
3. What are the key features of IP67 momentary tactile switches?
Waterproof and dustproof (IP67 rating).
Momentary operation (returns to default state when released).
Compact and durable design.
Tactile feedback (audible or physical click for user confirmation).
Wide operating temperature range (suitable for harsh environments).
4. Where are IP67 momentary tactile switches commonly used?
They are used in applications requiring durability and resistance to environmental factors, such as:
Consumer electronics (smartphones, wearables).
Automotive systems (control panels, external switches).
Industrial equipment (machinery controls).
Medical devices (portable and fixed equipment).
Outdoor and marine electronics (GPS, navigation systems).
5. What is the lifespan of an IP67 momentary tactile switch?
The lifespan typically ranges from 50,000 to 1,000,000 cycles, depending on the design, materials, and operating conditions.
