Round & Double Radius Domes

Round & Double Radius Domes

Our round and double radius domes are essentially designed for applications where space and height are critical.
Nicomatic offers round & double radius domes that are available with or without micro dimple or multiple dimples. Given their geometry these domes are more robust to overload, overstroke & sweetspot tests. Their small diameter & shape make them ideal for consumer electronics applications, and every man/machine interface of small size (calculators, GPS systems, PC mouse, joysticks, automotive…).
The double radius version allows to save even more space vs. the round.

General features:

  • Packaging in bulk or on array
  • Material: stainless steel with nickel plating
  • Temperature of use: -40°C to +105°C
  • Switching voltage: 0.1 to 100 V
  • Switching current 0.005 to 100 ma DC / Power at 1 Watt
  • Contact resistance < 100 mOhm
