All Ensto Origin switches can be directly actuated, and, in addition, all Ensto Origin rotary switches can be through-door (extended-shaft) actuated.

The wide range of accessories includes, for example, auxiliary contacts and handles.

Manual Motor Controllers andLocal Disconnect SwitchesEnsto Origin

Ensto Origin switches can be directly actuated or through-door (extended-shaft) actuated.

Our Ensto Origin line of small industrial switches has been private-labeled by major corporations worldwide, and has demonstrated its rugged reliability in thousands of applications – with a wide variety of mounting confi gurations.

Toggle-actuated Ensto Origin switches can be used with face covers for additional touch protection. The covers are also suitable for use in DIN cutout windows.

The range of load break switches is completed with a changeover mechanism, ideal for applications such as telecoms (in particular, cell phone masts), maintenance applications where a circuit needs to be in the “off” position while being worked on and power transferred to another circuit, and reversing the direction of a machine.
