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.
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
