Important:

This rotary switch is particular because it has a double wafer with, on one side the circuits and on the other side the contacts blades. Both sides can have 12 contact blades thus giving 12 different contacts, or it can have any combination of contact blades and circuits on each side.

  • The stops are user adjustable from 2 to 12 positions
  • Availlable with 12, 6 and 4 positions on a full turn
    • Version CC: Shorting contacts, (make before break)
    • Version E: Panel sealing, add 2mm to L
    • Version M: Navy quality with or without sealing
    • Version R: Straigth terminals to reduce L
  • Other versions:
    • Gold plated contacts 3µ over nickel plating
    • Open circuit
    • Biased indexing (momentary contacts)
    • Security system with pull or push to turn
    • Activation by RONIS or KABA key
    • Assembly with counter-turning indexing
    • Hollow shaft (diameter 6 x 3,1) for mounting with other components (switch, potentiometer)
    • Standard shafts and special shafts
