3-step enabling switch series ZA2

The B-COMMAND enabling switch ZA2 is a 3-stage (Off-On-Off) enabling switch, which was designed for installation on input devices. The 2 working contacts are change-over contacts, which offer the customer several wiring options.

The redundant contact configuration fulfills safety category 4. In addition to the two normally open contacts, the positive break auxiliary contacts offer options for monitoring.

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

The B-COMMAND enabling switches ZA2 are available with or without rubber cap. Besides the standard color yellow, we can also supply the enabling switch ZA2 with a grey or black rubber cap. For automotive applications our rubber caps for enabling switches are also available in silicone-free material.

If you have any questions about our enabling switch ZA2, we are always available by phone, e-mail or live chat.

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