Mechanical multiple position limit switches with positive opening

Cam switches

Available in:

38 versions

With mechanical multiple position limit switches in smaller configurations, safety switching elements are not feasible. In contrast, solutions with positive opening already exist. In these, the switching process is triggered by a rigid plunger that actuates a mechanical switching element with forcible opening. However, should this plunger move, it breaks the contact. This means that you have reliable control of switching processes, even with welded contacts.

Features

  • Also suitable for welded contacts
  • Two model series
  • Up to 12 switch positions, depending on the model series
  • Freely selectable number of switch positions with positive opening
  • Two-chamber system with IP67 degree of protection: Wear-free membrane with hermetic separation of the plunger mechanism and the switch interior
  • Maintenance-free, self-lubricating ram guide with plain bearing bush
  • Rigid plunger
