Electrical Specifications Contact Resistance: 50 milliohms max (15 milliohms initially). 100 milliohms max low level. Insulation Resistance: 50,000 Mohms initially (10,000 Mohms after life) at 100 VDC Voltage Breakdown: 600 Vac initially, 250 Vac after life Mechanical / Environmental Ratings Materials and Finishes Switch Base: Diallyl Phthalate per MIL-M-14 Bushing: Zinc alloy Detent Rotor: Nylon Detent Balls: Steel, nickel-plated Contact Spring: music wire Detent Spring: Stainless steel Shaft: Stainless steel Contact Grayhill if the life limiting criteria is more critical than those listed, if the required cycles of operation are greater than those listed, if a larger make and break current is required than the one listed for the desired number of cycles, or if elevated temperatures or reduced pressures are part of the operating environment. Shaft Seal: Ethylene Propylene Panel Seal: Silicone Rotor Contact: Silver cad-oxide, gold-plated Terminals and Common: Brass, gold plate .00002" minimum thickness over silver plate .0003" minimum. Mounting Hardware: One mounting nut .089" thick by .433" across flats and one external tooth lockwasher supplied with each switch. Mounting nut is brass, nickel plated and lockwasher is stainless steel. Additional Characteristics Contact Type: Non-shorting or Shorting, wiping contacts Terminals: Switches are provided with the full circle of terminals regardless of the number of active positions. Shorting Characteristics Typical values for current interruption during shorting: Temperature Duration Room Temperature to +85 C < 0.2 ms Reduced Temperatures < 20 ms Values present typical current interrupt for a single bounce in a pulse train of unspecified length when rotating between switch positions.
