CONTACT PROFILES

Saving precious metals
Our development and manufacturing processes are the basis for specific precious metal savings. Special profile forms and combinations of materials enable minimum use of precious metals without restricting the functionality of the component.

Specific saving of the precious metals gold, silver, palladium and platinum. Reduction of the layer thickness by replacing the basic material results in higher electrical conductivity. Optimum adaptation of the layer curve according to the switching function.

Conversion from solid contact Rivets to multi-layer contact profiles

Contact material

Solid contact rivets

Multi-layer contact profiles

Diffused gold layers
Diffused gold layers have proved their worth in the fields of micro-switches and Telecommunication Relays. This method developed by INOVAN combines ideal properties with minimum use of precious metals:
●

Electroplated layer

Diffused Au-layer

Au-layers 2-10µm thick have been replaced by diffused Au-layers of 0.5µm. Up to 90 % savings on gold. The influence of price fluctuations of precious metals is minimized.

Application examples
INOVAN contact profiles are used in signal relays, micro-switches, switches, push Buttons and regulators, relays and power switches.

Application of contact profile as a switching contact used for a micro switch.
