A household light switch may emit a small, harmless visible spark when switching. In an ordinary atmosphere this spark is of no concern, but if a flammable spark is present, the arc might start an explosion. Electrical equipment intended for use in a chemical factory or refinery is designed either to contain any explosion within the device, or is designed not to produce sparks with sufficient energy to trigger an explosion.
For one of our clients we designed a custom explosion proof prototype containing a 4 button capacitive touch keypad film with electronics and attached it to the reverse side of a 0.5” thick piece of glass. This glass was then installed into a special Nema 7 explosion proof enclosure.
Rapid Keypads can provide a custom printed glass graphic overlay and capacitive touch system for any application!
