Tactile Switches with Metal Domestactile membrane switch image

Metal Dome tactile switches are ideal for high reliability applications as they can undergo over one million actuations without losing its mechanical properties.   They can be used with copper or silver circuits and can be sealed.   The metal domes come in a variety of shapes, sizes and actuation forces.

Properties

  • Dome sizes range from 6mm to 20mm
  • Typical actuation life 5 million
  • Actuation forces range from 100 to 1000 gm
  • Typical contact bounce < 10ms
  • Maximum operating temperature -45C to + 85 C
