Electrical Ratings
Make-and-break Current Rating: 2,000 cycles
at 10 mA, 50 mVdc; 2,000 cycles at 125 mA, 6
Vdc; 2,000 cycles at 50 mA, 30 Vdc.
Contact Resistance: 100 mohms maximum
after life, measured at 10 mA dc and 50 mV
(open circuit). Initial values are 60 mohms
maximum for coded switches, and 50 mohms
for other linear action switches.
Insulation Resistance (at 100 Vdc):
Between adjacent isolated contacts: Initial:
5,000 Mohms minimum; After Life: 1,000
Mohms minimum
Across open contacts: Initial: 5,000 Mohms
minimum; After Life: 1,000 Mohms minimum
Dielectric Strength: Between adjacent isolated
contacts and across open contacts. Initial: 750
Vac; After Life: 500 Vac
Contact Carry Rating: 2 amps with a maximum
contact temperature rise of 20°C.
Mechanical Ratings
Mechanical Life: 4,000 cycles maximum. Note:
a cycle is one complete operation, back and
forth through all switch positions.
Vibration Resistance: 10 to 2,000 Hz at 15G or
0.060" double amplitude; no damage and no
contact openings exceeding 10 mS (Method
204, Test Condition B).
Shock Resistance: 509, 11 mS, half sine; no
damage and no openings exceeding 10
microseconds (Method 213, Test Condition A).
Environmental Ratings
Refer to MIL-STD-202F per MIL-S-83504
Operating Temperature Range: -40°C to +85°C
Storage Temperature Range: -55°C to +85°C
Moisture Resistance: 240 hours with
temperature cycling and polarization, per MIL-
STD-202F, Method 305
Materials and Finishes
Nonconductive Parts: Plastic UL94V-O
Shorting Arm: Phosphor bronze, gold plate
over nickel plate
Base Contacts: Copper alloy, gold plate over
nickel plate
