Standard Rope Pull switches
Because of their specifications governed by corresponding standards (see Cable Safety Pull Switches SRM/SR), these cable pull switches are used exclusively as safety command devices.
These switches are available in metal enclosures as well as in insulation-enclosed versions. They are operated manually by pulling on the attached cable.
Thanks to their pretension, these switches, which feature a switching contact with overlap, execute a switching function when the cable is pulled or in the event of cable breakage.
The field of application for these cable pull switches includes
- Opening and closing of (garage) doors
- Starting machines
- Issuing commands in production processes
The basic design of the standard cable pull switches is based on that of position switches.
