The E47 precision limit switches provide
high accuracy switching at an affordable
price. A variety of standard features, such as
current capacity, operating force, travel
characteristics and actuators let you custom
fit the switch to your application. The
switches are available in their compact basic
form or enclosed in a rugged metal housing.
Cost effective and compact.
