Panasonic – Industry’s thinnest push-button switch suitable for use indoors and outdoors


Panasonic Automotive and Industrial Systems Europe has introduced a surface-mount push-button switch which is just 0.53mm thick – the thinnest of its kind currently on the market.

The new Light Touch Switch, which has the part number EVPBB, is designed for use in wearable devices and personal healthcare equipment. Benefitting from a very light operating force of only 1.0N, yet still giving clear tactile feedback, the switch is water- resistant and dust-proof, as marked by its IP67 rating. This makes it suitable for use both indoors and outdoors.

In order to achieve reliable operation and useful tactile feedback while thinning the dimensions of the switch, Panasonic used a unique movable contact design, and technology which provides for precision processing and press operation.

In addition, Panasonic employed a new sealing method, in which the cover and the base undergo laser welding, to provide the IP67 grade of protection.
