Document Type and Number:
Japanese Patent JP4490616
Kind Code:
B2
Abstract:
The present invention relates to a safety switching device for connecting and safely disconnecting an electrical load, in particular an electrically driven machine. The safety switching device includes first and second electromechanical switching elements whose operating contacts are arranged in series with one another between a first input terminal and an output terminal of the switching device. Furthermore, the switching device has a second input terminal for receiving a switching signal. The switching signal acts on the switch position of the operating contacts of the two switching elements. According to a preferred embodiment, the first switching element has a lower nominal switching capacity than the second switching element.
