Non-Turn Washer
Brass, tin/zinc-plated washer, detailed above
may be purchased as a separate item.
ꢁart No. 19C1ꢀ14.
This rating is based on the following criteria:
Overload—5ꢀ operations at 125% rated ac load
and 15ꢀ% rated DC load.
Additional Characteristics
Single Pole, Single Deck: 2 to 11 positions
plus common 0ꢀ° 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: 0ꢀ to 75 ounce-inches on
a new switch. Approximately 22 ounce-inches
after 25,ꢀꢀꢀ cycles of operation.
Endurance—6ꢀꢀꢀ operations at rated load with
9ꢀꢀ Vac dielectric strength before and after test.
Temperature Rise—Not to exceed 0ꢀ°C when
carrying rated ac load after endurance test.
Contacts will carry 2ꢀ Amps at 115 volts AC with
0ꢀ°C maximum temperature rise.
Contact Resistance: (Measured at 2 Vdc and
approximately 1ꢀꢀ mA) for new switch
approximately 1ꢀ milliohms.
InsulationResistance:Approximately1ꢀꢀ,ꢀꢀꢀ
Mohms. Between mutually insulated parts.
Voltage Breakdown: Approximately 25ꢀꢀ Vac
between mutually insulated parts.
