Switching element, positive with roller

The switching module ER is suited for safety switches with positive actuation. This is only valid for one or several normally open contacts. Further precondition is the actuation over a sufficiently long distance, to result in a contact opening of minimal 2 x 2 mm results. The switching module is also used as auxiliary switch and is thus applied at key switches, limit switches etc. The plunger is equipped with a roller and can therefore be actuated by a ramped device.


  • plastic parts self-extinguishing
  • version NL preferably actuated to the left
  • version NR preferably actuated to the right
  • contacts with fine silver coating
  • positively driven normally open contact
