Rotary Switches
Single Deck Rotary Switches
SPECIFICATIONS
Electrical Rating
Rated: To make and break the following loads:
1 amp at 115 Vac resistive; 0.5 amp at 220
Vac resistive; 1/4 amp, 115 Vac inductive; 1/50
amp, 115 Vdc inductive, 1/10 amp, 6 to 28
Vdc inductive; 1/10 amp, 115 Vdc resistive; 1
amp, 6 to 28 Vdc resistive; to carry 10 amps
continuously.
Contact Resistance: 10 milliohms initial.
After 25,000 cycles of operation 20 milliohms
maximum.
Insulation Resistance: 50,000 Mohms
minimum initially
Voltage Breakdown: 1,000 Vac (500 Vac, or
better after most environmental tests).
Life Expectancy: 100,000 mechanical cycles
of operation normally.
NOTE: Actual life is determined by a number
of factors, including electrical loading, rate of
rotation, and environment, as well as maximum
contact resistance, minimum insulation
resistance, and minimum voltage breakdown
required at the end of life.
Materials and Finishes
Switch Base: Melamine per MIL-M-14 (ASTM-
D-5948)
Cover, Stop Washers, Bushing: Brass, tin/
zinc-plated
