**Hard gold plated contact. A distinction for this contact is made between following apaplications:
1. Small load range in which the gold layer is removed by a small extent only. 50 mW (5 V/2 mA) to 1,5 W / 24 V (Resistor
load)
2. Medium or high load range in which after a few or after one switching the hard gold plated layer is removed and the
properties of the contact base material AgNi take effect.
