  • Human hand, finger or foot activated switches.

  • Indestructible electronic switch replacements for standard toggle or push-button switches.  Great for museums, exhibits, interactive displays, jails, schools or hospitals switches for wheel chairs or for the handicapped.

  • Object sensors, including humans.

  • Automatic product quality inspection, missing part, empty bottle.

  • Fluid level sensors, liquids and powders.

  • Lighting controls, touch activated dimmers.

  • Hand “hover” switches, activated without making contact with any surface.

  • Through glass, wall or door switches.

  • Touch sequence switch controls.  Touching one button could control multiple loads.

  • Detecting human feet from beneath a floor.

  • Non contact object sensors for material handling needs.

  • Security alarms, human motion detection, hidden alarm reset switch.
