ABSTRACT:
A front mounted rectangular pushbutton switch is clamped within a hole in the panel by screws accessible through a front opening of the switch housing which drive an external clamping assembly against the rear of the panel at the midpoints of four sides of the switch housing. The clamping assembly employs two screws at diagonally opposed corners of the housing, each of which controls movement of a clamp on two adjacent sides of the switch.
