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 loadlife 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 critical than those listed; longer operation is required; a larger make and break current is required; the operating environment includes elevated temperatures or Rotary 12 reduced pressures. Contact Carry Rating: Switch will carry 6 amperes continuously with a maximum contact temperature rise of 20°C. Additional Characteristics 200 Contact Type and Forces: Shorting or nonshorting 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.
