SwitchAir Metal Domes

SWITCHAIR® METAL DOMES

Nicomatic's patented SwitchAir® technology ensures that the domes do not stick together thereby elimating the possibility of "double-doming". Due to the fact that the domes do not stick together it is also possible to introduce various levels of automation to the placement of the metal domes and hence reducing the cost of use.

The benefits of using patented SwitchAir® domes are:

  • Eliminates "double-doming"
  • Excellent tactile effect even after rigorous overload tests
  • Life cycle: 1 million cycles guaranteed
  • Stable forces
  • Control of dimensional tolerances
  • No burrs thus eliminating the scratching effect
  • Wide temperature range
  • Reduced placement cost
  • Elimination of contamination risks
  • Available in loose, tube or as an array

Production Capacity

Nicomatic is one of the worlds largest producers of metal domes:

  • 3 million domes per day
  • 700 million domes per year

Quality Control

  • 1 million actuation guaranteed

Typical force versus travel curve for a metal dome: this force is generated using a standard steel test probe on computer controlled equipment.

  • Optical tri-dimensional equipment which controls domes precisely
