Protection Class: IP65 (according to IEC529)
Door Operating Radius:
4 Degrees to Open the Normally Closed Contact
8 Degrees to Close the Normally Open Contact
Switch is in the normal position when the door is Closed
Turning angle (Maximum) Extreme to Extreme = 180 degrees


  1. Connect Safety Circuits to the Normally Closed Contact (11-12 or 21-22). Contacts are Normally Closed when the door is closed. Normally Open contacts are for indicating circuits and are not for use in the safety circuit. The Normally Closed contacts open when the switch arm is rotated open more than 4 degrees and close when the switch arm is rotated more than 8 degrees.
  2. Mount the switch into the machine using tamper-resistant fasteners (not supplied). Always use washers under the switch mounting fasteners to prevent the fasteners from pulling through the switch mounting holes.
  3. The head of the switch can be rotated in 4 x 90 degree steps allowing 4 different shaft rotating positions. To rotate the head; remove the 4 head attachment screws, rotate the head into the proper position and reinsert the head attachment screws. Head Screw Tightening Torque = 7 inch lb. (0.8 Nm)
  4. Do not use the switch as a mechanical stop.
  5. Attach the switch to the body of the machine and attach the sliding follower (not furnished) to the door of the machine. The sliding follower is to be permanently attached to the slotted lever and must freely slide down the slotted lever as the door opens. This action rotates the slotted lever operating the safety switch. Carefully position all of the components so the sliding follower operates the switch at the proper point and the travel of the follower does not exceed the length of the slot.
  6. Verify proper operation of the Safety Switch before placing the machine in service.
