Terminals: Switches have the full circle of
terminals,regardlessofnumberofactivepositions.
Stop Strength: 7.5 lb-in. minimum
Rotational Torque: ꢀ.5 to 9 oz-in. (21-5ꢀ mN-
m), depending on the number of poles.
Bushing Mounting: Required for switches with
stops, and recommended for switches without
stops.
One cycle is ꢀ60° rotation clockwise and ꢀ60°
return. The data for the curve was measured at
sea level, 25°C and 68% relative humidity with
the life limiting criteria which follows.
Contact Resistance: 100 milliohms maximum,
(15 milliohms initially).
Insulation Resistance: 10,000 Mohms
minimum between mutually insulated parts
(50,000 Mohms initially).
Voltage Breakdown: 600 Vac minimum
between mutually insulated parts at standard
atmospheric pressure.
Meets MIL-S-3786 for:
High and medium shock; Vibration (10 to 2,000
Hz); Thermal shock (-65° to 85 ° C); Salt spray;
Explosion; Stop strength (7.5 in-lbs. minimum
(.85 N-m); Terminal strength; Sealed styles
withstand water pressure of 15 PSI minimum
(10ꢀ KPa) without leakage.
Life Expectancy: As determined from the load-
life curve for the current to be switched. Contact
