| S826 Series switches feature galvanically isolated contact bridges that make The S834 enabling switch is typically used in automatic handling machines it possible to control two separate load circuits with independent voltage and robotics. When installed in such devices, the S834 greatly increases the levels at the same time. safety of the operator in the working area. The wiping, double-breakcontacts ensure high reliability even at low electric During operation of the machine the enabling switch must be held in the loads. Switches with gold contacts are particularly suitable for low currents working position to maintain closure of the circuit. In case of emergency, the and voltages. operator merely has to release the pressure on the button for the machine to stop immediately. The same is true for panic reaction, where the increased application of pressure will stop the machine. | |||||||||||||||||||||||||||||||
