Standard Pushbuttons
Hubbell's standard 22.5mm pushbuttons feature polyester construction for superior
corrosion resistance, and the #6 terminal screws have self-lifting captive wire
clamps to accommodate #22 through 2 - #12 wires per terminal. The pushbuttons
mount in a round 22mm or 7/8" hold and directly interchange with competitive
units. These pushbuttons are rated for NEMA 1, 2, 3/3r, 4/4X, 12 and 13
installations and are UL/CSA approved.

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.
