When depressed, enabling switches are designed to operate in only one position, causing a stop condition in any other position. In hazardous locations, the safety guarding may need be disabled. An enabling switch allows for the machine operation to occur under these conditions. Euchner offers two position (OFF-ON) ZSA (dead-man) and three position (OFF-ON-OFF) ZSA, ZSB, ZSR and ZSM (live-man switch) versions. Handheld enabling units and individual buttons for installation are available.
Euchner ZSG, ZSE and ZXE pushbuttons enabling switches are designed for use in pendant stations (HBA, HBL, HBM, HBE) and control panels to provide a wide selection of two position (OFF-ON) dead-man switch and three position (OFF-ON-OFF) live-man switch.
