People, actors, machines and stage technology often meet on theatrical stages. This inevitably leads to injury potential.
In order to minimize the risk, it is suitable to use an enabling switch in some places. 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 in the design. In the event of a 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 the system would be stopped. The 2nd stage must therefore be actively actuated and held.
