Wireless position switches are applied where moving parts of machinery and plant systems must be positioned or switched off. The various application fields also include security tasks in different sectors of industrial building automation, drinking water storage and regenerative energy supply. There are different versions available with metal and thermoplastic enclosures. An electrodynamic energy generator or a long-life lithium ion battery serves as the energy source. Because of their high protection class, the wireless switching devices are suitable for indoor and outdoor applications.
