Control arrangement for mains-operated apparatuses that are supplied with a low voltage and provided with a mains activation device

Abstract

A control arrangement for apparatuses (1) with several functional actuators that are operated with an electrical voltage, in particular a low voltage and supplied by a mains-operated transformer (2) that is provided with a mains activation device, wherein said control arrangement includes a) a switching unit (3) that is consolidated into a manually operated switching panel (12) and serves to control the functional actuators and the mains activation device of the apparatus (1) to be controlled, b) several electrical switching contacts on the switching panel (12) that can be mechanically actuated and that are realized, in particular, in the form of pushbuttons (10A, 10A′), and c) transmission means for transmitting control commands to the mains activation device and to the functional actuators. The switching unit (3) is simplified due to the fact that separate switching contacts (4, 4′) and (5, 5′) and separate transmission means (4A) and (5A) are respectively provided in the switching unit (3) for the mains activation device on the one hand and for the functional actuators on the other hand, such that the control circuits of the mains activation device and of the functional actuators are permanently separated from one another. This also eliminates the problem of competing voltage supplies of the switching unit.
