15 Amps, 120 Vac, non-inductive load.
One Amp, 120 Vdc, non-inductive load.
AdditionalGrayhillRating:7.5Amps,220Vac,
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.

Mounting Hardware: One mounting nut /16"
across flats, 3/32" thick and one non-turn washer
(see detail) are supplied with each switch.
