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.
