Changes

AgPd alloys are mostly used in relays for the switching of medium to higher loads (>60V, >2A) as shown in <xr id="tab:tab2.20"/> (Table 2.20). Because of the high palladium price these formerly solid contacts have been widely replaced by multi-layer designs such as AgNi0.15 or AgNi10 with a thin Au surface layer. A broader field of application for AgPd alloys remains in the wear resistant sliding contact systems.
