Additional Characteristics
Contact Type and Forces:
Shorting or non-
shorting wiping contacts with over 25 grams of
contact force.
Shaft Flat Orientation:
Flat opposite contacting
position of pole number one (see circuit diagrams).
Terminals:
Switches have the full circle of
terminals, regardless of number of active positions.
Stop Strength:
7.5 lb-in. minimum
Rotational Torque:
3.5 to 9 oz-in. (21-53 mN-
m), depending on the number of poles.
Bushing Mounting:
Required for switches with
stops, and recommended for switches without
stops.
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
(103 KPa) without leakage.
CYCLES x 1000

One cycle is 360° rotation clockwise and 360°
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.
Life Expectancy:
As determined from the load-
life curve for the current to be switched. Contact
GRAYHILL for more information if any of the
following is true: the life limiting criteria are more
