MS27754F Canceled MS part number 1/ Substitute part number 1/ Available locking combinations MS27754-1 -2 -3 -4 -5 -6 MS27754-34 -35 -36 -38 -39 -40 All E, F, K, L, M, N E, L, N All E, F, K, L, M, N E, L, N Circuits made with toggle lever in Opposite Keying side Center position keying side 1-2 4-5 2-3 5-6 On 2-3 on 4-5 On Mom-on 2-3 on 4-5 On Mom-on 2-3 on 4-5 Mom-on On 1-2 on 5-6 On Mom-on 1-2 on 5-6 On Mom-on 1-2 on 5-6 Mom-on 1/ The canceled part numbers are no longer acquirable; the substitute part numbers have a lower dielectric withstanding voltage at reduced barometric pressure (see test voltage requirement below). 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 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 molded 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 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 .045 pound. Electrical ratings for 28 V dc and 115 V ac at 400 Hz. Lamp load = 1 ampere, resistive load = 5 amperes, inductive load = 2 amperes. Part or Identifying Number (PIN) example: MS27754-36L (locking combination "L"). 3 Source: https://assist.dla.mil -- Downloaded: 2018-10-13T10:04Z Check the source to verify that this is the current version before use.
