Waterproof PET Membrane Keypad Metal Dome Membrane Switch
Membrane switches also called membrane keypads to have very wide applications and also have many different using environments. For example in a wet environment, outdoor under sunshine UV and bad weather of rain, boat sailing on the sea, etc. Then a waterproof and anti-UV membrane keypads are necessary for such kind of special application.
LUPHITOUCH manufactured waterproof membrane keypads can meet IP67 and NEMA-4 waterproof standard. For outdoor use, especially exposed under the sunshine UV, anti-UV membrane keypads are also necessary. The common membrane keypads can be easily damaged by strong ultraviolet rays. Although no impact on the function, the graphic overlay will have become ugly and the printed graphics can be faded in a not long time.

In LUPHITOUCH we use anti-UV PET materials outdoor using membrane keypads. For example the Autotex XE series materials.
For waterproof keypads, we can design a waterproof frame on the membrane keypads to prevent the water from going into the circuit. Also can use rubber keypad wrapped the PCB circuit and use seal the connection circle.
In these special environment applications, the anti-UV and waterproof membrane keypads quality are very important. If the water went into the circuit it will cause your control board failure and then easily cause safety accidents. So a good supplier of such kind of membrane keypads is very important for your application.
