What the description tells you about fit
The description — "PB ILLUM 2POS MOM EXTND 120V RED 1NO+1NC" — decodes to a 22 mm panel-mount illuminated pushbutton with a two-position momentary operator (extended actuator), a 120 V red LED, and one normally-open plus one normally-closed contact. The extended operator projects further from the panel face, suited for applications where the button needs to be reached through a guard or thick overlay.
