Push Button Elements 2040-1

Specification Sheet • March 1992 • New

Hubbell's 22.5mm oil-tight push buttons and selector
switches offer clean styling with simple installation.
Hubbell's push buttons are designed to save space in
modular designed panel installations. All of the devices
mount from the rear of panel in a 22.5mm (7/8") diameter
hole, and are secured from the front by an octagonal
mounting nut.

Hubbell's push button components are designed to be used
in the machine tool, food services and many heavy
industries. These components offer NEMA 4X rating for use
where corrosion resistance, water/oil/dust tight switching
mechanisms are required. Their simple standardized
mounting configuration makes them an excellent selection
for all kinds of equipment where panel mounting is
possible—indoor or outdoor.

Hubbell's push button switches allow for quick and easy
conversion of button/pilot colors and number of contacts;
allowing you to reduce the amount of component inventory
necessary for normal maintenance. In addition to the push
buttons and selector switches, Hubbell carries a complete
line of pendant stations, enclosures and other wiring devices
to complete your installation.

Maintained Pushbuttons

Hubbell's maintained pushbuttons are available in two variations. Single button
mushroom head "push-pull" units are stand alone buttons that are commonly used
for a maintained "emergency stop" function which has "push-to-stop/push-to-start"
operation. Single maintained buttons are used with another operator and an MRI
"maintained reset interlock" to provide two button operations for either
"maintained/maintained" or "maintained/momentary" action.
