CYCLES x 1000
115 Vac 0r 30 Vdc
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.
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.
Life Expectancy: As determined from the load-
life curve for the current to be switched. Contact
