The Harsh Environment Solution

For harsh environment applications where a membrane switch may be exposed to water, dust, extreme temperatures, and harsh cleaners, the XyWeld® sealed switch is the solution! The Xymox XyWeld® spacer involves a specialty adhesive bonded with a proprietary heat activated process to yield a spacer that is much more robust than a standard PSA.
