REQUIREMENTS: All switches on this standard are designed so that the movement of the switch mechanism is opposite to that of the toggle lever. Test voltage for dielectric withstanding

8、 voltage at reduced barometric pressure, shall be 400 V rms minimum. Electrical endurance shall be performed for 30,000 cycles. Mechanical endurance shall be performed 50,000 cycles at -65C and then 50,000 cycles at 85C. Intermediate current shall be performed for 30,000 cycles. Terminals shall be m

9、olded into the switch case and shall accommodate No. 18 AWG wire. Locking arrangement: Positive locking shall be accomplished and shall prevent motion of the toggle lever until the locking mechanism is manually released. The force required to release the locking mechanism shall be 3 to 5 pounds. The

10、 locking means at the top of the toggle bushing shall be capable of withstanding a torque of 20 pound inches applied in both directions immediately following the humidity test. Maximum weight shall be .066 pound. Electrical ratings for 28 V dc and 115 V ac at 400 Hz. Lamp load = 1 ampere, resistive
