The ZSM is more than just a conventional enabling switch. Due to its modular design a large number of additional functions can be integrated. Additional components such as emergency stops, LED displays or a key-operated rotary switch make the ZSM a multifunctional item. A special feature of the ZSM is the new vibration signal that tells the operator whether the enabling switch is in the enabling position. With its rubberized grip, the switch lies securely in the hand. The well thought-out design and the low weight result in fatigue-free working. Environmental protection up to IP 65 with cable shielding for reliable monitoring.
