Tactile Switches with Metal Domes

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 -45°C to + 85º C
  

     Completely sealed and raised surface

Design Advantage	Performance Results
Low profile, flat surface, compact keypad spacing	Provides switching in smaller spaces, with less  weight and easily cleanable surfaces
Wide range of actuation forces	Human factor sensitivity can be pinpointed for maximum response
Controls can be placed where most needed	Greater ease of use by control operator
Reduces demand for large switch construction on control panel	More efficient use of materials
Replaces mechanical actuation devices	Ideal for portable instrumentation
Completely sealed construction	Prevents permeation of chemicals, oils and contaminants
