Need to know what are the changes from XB2 to XB4

Product Line:
Push Buttons and Operator Interface

Harmony Pushbuttons XB2/XB4

The XB4 requires only 1 screw to tighten on the mounting collar verses 2 on the XB2. This allows easier installation. The XB4 push buttons can accept 3 contact blocks side-by-side-by-side for a total of nine contacts on non-illuminated devices. Using the XB4 Protected LED light modules and contacts on each side will allow shallower depth than the XB2 on illuminated devices.
