Safety Switches
Product Description
SAFETY SWITCH
A safety switch is used to open or close an electrical
circuit. Non-fusible safety switches provide a means
to manually connect or disconnect the equipment
from the power source. Fusible safety switches pro-
vide a means to manually open and close a circuit and
overcurrent protection by using customer-installed
fuses. Safety switches are also commonly referred
to as a disconnect switch or simply a disconnect.
DP221NGB Plug Fuse Safety Switch,
30 Amperes, 120/240 Volts
DOUBLE THROW SAFETY SWITCH
A double throw safety switch is sometimes referred to
as a transfer switch. It performs the same function as a
safety switch by opening or closing a circuit; however,
its primary use is to transfer service from a normal
power source to an alternate source (i.e., a residential
generator) or to switch from one load circuit to another.
