Switches from Eaton’s electrical
business provide high accuracy
switching at an affordable price.
A variety of standard features, such
as current capacity, operating force,
travel characteristics and actuators,
lets you custom fit the switch to your
application.
The switches are available in their
compact basic form, or enclosed in a
rugged, metal housing.
