SPECIFICATIONS
Electrical Rating
Rated: UL Recognition: File Number E35289
15 Amps, 120 Vac, non-inductive load.
One Amp, 120 Vdc, non-inductive load.
Additional Grayhill Rating: 7.5 Amps, 220 Vac,
non-inductive load.
This rating is based on the following criteria:
Overload—50 operations at 125% rated ac load
and 150% rated DC load.
Endurance—6000 operations at rated load with
900 Vac dielectric strength before and after test.
Temperature Rise—Not to exceed 30°C when
carrying rated ac load after endurance test.
Contacts will carry 20 Amps at 115 volts AC with
30°C maximum temperature rise.
Contact Resistance: (Measured at 2 Vdc and
approximately 100 mA) for new switch
approximately 10 milliohms.
Insulation Resistance: Approximately 100,000
Mohms. Between mutually insulated parts.
Voltage Breakdown: Approximately 2500 Vac
between mutually insulated parts.
Materials and Finishes
Rotor Contact: Silver alloy
Stator Contact: Silver alloy
Shaft: 303 Stainless steel
Stop Rivet: Steel, tin/zinc-plated
Mounting Bushing: Brass, tin/zinc-plated
Base and Drive Hub: Heat resistant, electrical
grade phenolic.
Mounting Nut: Brass, tin/zinc-plated or stain-
less steel.
Detent Mechanism: Brass, silver-plated
“Faston” Terminal: Brass, silver-plated
Solder Terminal: Brass, silver-plated
Mounting Hardware: One mounting nut
9 / 16 "
across flats, 3 / 32 " thick and one non-turn washer
(see detail) are supplied with each switch.
Additional Characteristics
Single Pole, Single Deck: 2 to 11 positions
plus common 30° Indexing.
Contacts: Non-shorting type
Stops: A rivet provides the fixed stop on all
switches. Minimum number of positions is 2,
and maximum is 11. Terminal 12, the common,
is isolated from rotation.
Rotational Torque: 30 to 75 ounce-inches on
a new switch. Approximately 22 ounce-inches
after 25,000 cycles of operation.
Contact Force: Approximately 12 ounces
Shaft Flat Orientation: Opposite point of con-
tact (see circuit diagram).
ACCESSORIES
Screw Terminal Adapter
Spring loaded, plug-in adapters for ‘Faston’
Terminals provide excellent mechanical fit and
electrical contact. Adapter material is brass
tin-plated. The terminal adapters are avail-
able with a 6-32 thread (-1) or 8-32 thread
(-2). A 1/4" panhead screw is provided as
part of the adapter.
