Switches

The Multiple Station Switch now
makes it possible to incorporate from
two to four EA700 Namco Series Snap­Lock Limit Switches into a single
assembly. Here’s a unit that can be
adapted to most any application where
individual limit switches are mounted
side by side. This single assembly
reduces installation time, cuts wiring

costs and presents a more compact

appearance than individually mounted
switches. Furthermore, you can now
perform an almost unlimited number of
switching functions within a single
enclosure by combining the Single Action
type switches.

Select the operating lever for your
application with regards to dimensions
and materials required.

Requests for operating levers not
shown should include lever style and all
pertinent information as to limit switch
number, dimensions, materials, etc.

Depending upon your application,
levers are available in cold rolled steel,
stainless steel, or bronze. Rollers are
available in steel, nylon, Bryl. Cop.,
stainless steel or steel ball bearings.
Please consult materials column of the
lever of your choice.

This style and size operating lever
is considered standard for the majority of
snap-lock switch installations. The
EL010-53420 (D1260) lever is steel with
a nylon roller and a stainless steel roller
pin. Like all snap-lock levers, the serrated
mounting hole matches the serrated lever
shaft of the switches to provide fixed
adjustment of the lever in 7.5° increments.
