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 command devices.
• These switches are available in metal enclosures as well as in insulationenclosed 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.
