Abstract

In order to switch high loads, an off-delay relay (A) with arc-resistant contacts (a1, a2) and an on-delay relay with highly conductive contacts (b1, b2) are connected in an energising circuit, while their contacts are connected in parallel in the load circuit. When the energising voltage is applied, the first relay (A) thus responds first; when the energising voltage is interrupted, this first relay is the last to switch off so that its arc-resistant contacts in each case take over the switching-on and switching-off current, while in operation itself, the low-resistance contacts of the second relay (B) carry the major part of the current. <IMAGE>
