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.
XyWeld® allows you to use a membrane switch in applications which may be exposed to water, dust, extreme temperatures, and harsh cleaners.
