→6.2 Contact Materials and Design of Contact Components
|PdCu15 and 40 (Anode) vs. AgNi0.15, AgCu3 (Cathode), Ag/ZnO, Ag/SnO2
|Contact rivets, welded miniature profile (tape) and strip segments
|-
|Breaker points (automotive ignition)
|Very high arc erosion resistance, high switching frequency
|W
|Tips or discs welded to formed parts or Fe supports
|-
|Automotive horn contacts
|High arc erosion resistance at extremely high number of switching operations
|W, Ag/SnO2
|Contact rivets, W weld buttons, springs or formed parts with brazed or welded tips
|-
|Appliance switches
|Low contact resistance, reasonable arc erosion and weld resistance
|AgNi0.15, Ag/Ni, Ag/SnO2, (Ag/CdO)
|Contact rivets, welded contact parts
|-
|Temperature controllers (Thermostats)
|Defined contacting point even at slow motion make, high operating temperatures
|AgNi0.15, Ag/Ni, Ag/SnO2, (Ag/CdO)
|Contact rivets, welded contact parts, weld buttons
|-
|Wiring devices (Light switches)
|Low contact resistance, reasonable arc erosion and weld resistance
|AgNi0.15, AgCu, Ag/Ni, with make peaks also Ag/ZnO, (Ag/CdO)
|Contact rivets, welded contact parts
