1/ Th e 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 -65°C and then 50,000 cycles at 85°C.
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 manuall y 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 dire ctio ns imm ediat ely 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 combin at io n "L").
