Actuating force: 9 ±3 pounds.
Release force: 4 pounds minimum.
Movement differential: .020 inch (0.50 mm) maximum.
Pretravel: .040 inch (1.01 mm) maximum.
Overtravel: .125 inch (3.17 mm) minimum.
Full overtravel force: 30 pounds maximum.
Coincidence of operating and releasing points: All poles shall transfer within .010 inch of plunger
travel.
Strength of actuating means: 30 pounds.
Contact resistance:
Silver contact switches: Not applicable.
Gold contact switches: In accordance with MIL-PRF-8805, plus .015 ohm maximum per lead per
foot.
Dielectric withstanding voltage:
