The B-COMMAND enabling switch ZB1 is a three-stage (OFF-ON-OFF) enabling switch, which can be ideally used as enabling switch in the danger zone. The housing of the ZB1 was developed especially for long-term use and impresses with its ergonomic housing shape.

The two working contacts of the integrated enabling switch are change-over contacts, which offer the customer several wiring options. The redundant contact configuration meets safety category 4.

 

Beside the enabling switch it is possible to mount an emergency-off mushroom button or a simple push-button on top of the housing. We offer a wall mounting bracket for easy fixation. 

For optimum operating comfort, the actuation force from position 2 to 3 for centric and eccentric pressure is absolutely identical: Even switching with only one finger at the outer end is reliably possible.

In addition, the B-COMMAND enabling switch ZB1 can be equipped with an auxiliary contact (NC contact), which can take over the monitoring function. In addition to the standard rubber cap color yellow, the ZB1 can also be fitted with a silicone-free grey rubber cap, which makes it suitable for use in the automotive industry.

 

If you have any questions regarding our enabling switches we are available for you by phone, e-mail or live-chat.

3-Stage Operation Enabling Switches (IEC 60947-5-8)

The function of our enabling switches is 3-stage or based on 3 positions. The working contacts are actuated in the middle position. For this purpose, we have implemented a clearly noticeable pressure point on the design side. In the event of panic / injury, the operator would either press firmly (3rd stage) or release the handle (1st stage). Both times the working contacts would be deactivated and the system would be stopped. The 2nd stage must therefore be actively operated and held. It is mainly used for setting up or maintaining machines or robots within hazardous areas.
