Abstract

A control switch for operating a machine, the control switch including a housing that includes a gripping region for an operator, and a detecting device for detecting an operator. The control switch further includes a safety circuit for activating the control switch when an operator is detected, and deactivating the control switch when the operator is not detected. The safety circuit includes a detecting device that includes at least one sensor operable to detect in a near field an operator's hand holding the control switch in the gripping region. The detecting device includes at least one additional sensor which detects a use of the control switch.
