Electrical Relay and Connection Technology

Electrical Contact Materials

We offer cadmium-free silver oxide contact materials for a wide range of applications.

Fine oxide particles are evenly dispersed in contact materials for relays and switches to improve durability and contact reliability. Upon your request, we offer these silver oxide contacts in various shapes such as rivet contacts and crossbar contacts.

Features

  • Stable contact resistance with evenly distributed oxides
  • Improved durability with excellent welding resistance
  • Excellent wear resistance and even erosion patterns have enabled lighter, thinner, and smaller contacts and contributed to a reduction in costs.
