Assembled Membrane Switches

Vmanx membrane switch assemblies combine electronic components, such as LEDs, photo diodes resistors and capacitors that are mobilized to the membrane switch substrate using conductive adhesive technology. Vmanx’s advanced manufacturing can print double-sided silver circuits producing the equivalent of four layer PCBs or the elimination of printed crossovers for environmentally exposed applications. These advances are customized in a variety of configurations to fit increasingly smaller, more demanding and cost competitive applications.

 

Features of Vmanx assembled Membrane Switches

  • Assembled membrane switch combines light weight, small size, long life
  • Moisture, dust, impact, shock resistant lead off around good
  • Vacuum molding touch-sensitive keys, the adapter-connector installation, set the LED as a whole, easy installation.
