ABSTRACT:
A multi-function electrical switch assembly (22) is disclosed that is mountable to a mosaic control panel (12) used in the controlling and monitoring of large complex traffic flow systems. The switch assembly has a bi-directional actuating mechanism including a shaft (24) that is movable axially as well as rotationally to actuate individual electrical switches (110, 112, 114, 115, 118, 120, 122, and 124). The switch assembly includes a housing (30) having an interior cavity (56) and interior walls (36, 46) to which individual switches are secured. The shaft (24) extends through the interior cavity (56) and has a rocker cam (224) and a linear cam (254) coupled thereto for actuation of various combinations of the switches. Return spring units (202) and (168) return the shaft (24) to its rotational and axial neutral positions when the shaft is released. An override spring unit (244) is coupled to the rocker cam (224) to absorb over-rotation of the shaft (24) and prevent damage to the switch mechanism.
