Abstract
A wall command switch (10) comprising a main frame (9) insertable over a conventional switch plate (50) and having a base portion (20) and an essentially planar pressure plate (15) rockably mounted within the base portion and substantially co-extensive therewith. An electrical switch (28) is mounted on the bottom surface of the main frame and a switch operator (35) is attached to the pressure plate in alignment with operable portions of the electrical switch so that rocking of the pressure plate moves the operator into engagement with the electrical switch. Structure in contact with the pressure plate to return the pressure plate to an unrocked position is provided. The base portion (20) also mounts a vertically moving override switch operator (55) which in turn moves through an actuator (70) an inwardly located position switch (77) which can allow automatic-manual or off functions of a light electrically connected to the command switch.
