The power switching circuit has a switch contact (1) coupled to a bus coupler (5), with the electrical load (15) connected to an energy supply line (30) via a switch (25) controlled by a second bus coupler (20). Both bus couplers are connected to a bus line (10), the operation of the switch contact causing the first bus coupler to send a load address and the required switch function in the form of a data telegram, the second bus coupler controlling the switch for the addressed load, in accordance with the switch function. The bus couplers can be contained in a common housing (35).
