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 continu-
ously.
Contact Resistance: 10 milliohms initial. Af-
ter 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 environ-
ment, 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 and Nut:
Brass, cadmium-plated
Contacts: Both shorting and non-shorting
wiping contacts have over 300 grams
contact force.

ORDERING INFORMATION
Switches are single deck, one pole switches of
2 to 10 positions. They have plastic or steel
shaft, with solder lug or PC terminals, with either
shorting or non-shorting contacts (plastic shaft
PC mount in non-shorting only). Ten position
switches have continuous rotation; fixed stop
switch with a metal shaft is available by special
order. Base part numbers are as follows:
Lug style, steel shaft:
Lug style, plastic shaft: 24B36-01-1-X*
PC style, steel shaft:
PC style, plastic shaft: 24P36-01-1-X*
The X is replaced with the number of positions
required (02, 03, etc.) Complete the part num-
ber by adding N for non-shorting contacts or S
for shorting contacts.
Available from your local Grayhill Distributor.
For prices and discounts, contact a local Sales
Office, an authorized local Distributor or Grayhill.
