BERNSTEIN

Si1/Si2 rope pull switch

Because of their specifications governed by corresponding standards, 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.

 

Features:

 

  • Die-cast aluminium switch body
  • Aluminium plated cover
  • Zinc die-cast pull ring
  • 2 x M20 x 1.5 cable entries
  • Conforms to VDE 0660 T100, DIN EN 60947-1, IEC 60947-1
  • Conforms to VDE 0660 T200, DIN EN 60947-5-1, IEC 60947-5-1
