Important:
  • The stops are user adjustable from 2 to 28 positions
  • Availlable with 28, 14 and 7 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 SP: Solder terminals are replaced by solder pins for PCB mounting
    • Version R: Straigth terminals to reduce L
  • Other versions:
    • Gold plated contacts 3µ over nickel plating
    • Improved insulation to 5 or 8 KVDC between poles and ground
    • Open circuit
    • Make before break on the positions not utilised
    • Activation by RONIS or KABA key
    • Assembly with counter-turning indexing
    • Hollow shaft (diameter 6 x 3,1 o diameter 10 x 6,1) for mounting with other components (switch, potentiometer)
    • Standard shafts and special shafts
