The ASCO 175 Remote Control Switch
All-Purpose Remote Control Switch Designed For Double-Throw Capability And Load Control
The ASCO 175 Remote Control Switch is a double-throw,
mechanically held remote control switch that is used in
applications requiring one or another load to be supplied
from a common source.
Its true, double-throw nature prevents both loads from be-
ing simultaneously connected to the single power source.
Each switch is available for single phase or 3 phase applica-
tions in sizes from 30 to 1200 amps.
