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.
