CONTROLLER FOR ELECTRIC OPERATING MACHIN

摘要

The device comprises at least one actuating element which emits a signal in response to blowing and/or suction airflow from a person and which is connected to a mouthpiece. The actuator is coupled to the appliance so as to be controlled by an evaluation circuit. Two position transmitters are coupled to further inputs of the evaluation circuit, which pref. includes at least one microprocessor. When the mouthpiece is used, each transmitter emits a coordinate signal charicteristic of the position of the mouthpiece in a coordinate system. The microprocessor processes the signals from the actuator, which is pref. in the form of an impact pressure transducer.
