Abstract

A wall controller for controlling the speed of rotation of a ceiling fan and the intensity of light of a lighting fixture, which includes a junction box covered with a slotted mounting plate to hold a control circuit assembly, a cover plate connected to the mounting plate to hold a switch control slide assembly therebetween, the control circuit assembly is consisted of two switches moved by two control slides of the switch control slide assembly to control the operation of the lighting fixture and the ceiling fan respectively.

Claims

1. A wall controller comprising:

a cover plate made in a rectangular shape having two slide slots, and pairs of back hooks;

a switch control slide assembly, said switch control slide assembly comprising two vertical parallel rails, two control slides respectively mounted and slid on said rails and extended out of said cover plate through said slide slots, and angle strip horizontally connected to said vertical parallel rails at bottom end thereof, each control slide having a resilient mounting portion for inserting said rail, and a recessed hole;

a mounting plate connected to said cover plate to hold said switch control slide assembly therebetween, said mounting plate comprising two switch slots corresponding to said slide slots on said cover plate, two downward hooks respectively projected from said switch slots at top end thereof, a horizontal support extends backward from said switch slot at bottom end thereof, pairs of retaining notches, on which said back hooks of said cover plate are hooked respectively, and round holes at four corners of said mounting plate around said switch slots;

a control circuit assembly supported on said horizontal support of said mounting plate, said control circuit assembly comprising two switching devices mounted on a circuit board by two face panels, said face panels being respectively inserted in said switch slots on said mounting plate and hooked between said downward hooks of said mounting plate and said angle strip of said switch control slide assembly, each switching device being respectively engaged into said recessed hole on either said control slide and moved by the respective control slide to control the speed of rotation of a ceiling fan or the intensity of light of a lighting fixture, said circuit board comprising a lighting fixture neutral wire, a hot wire, and a ceiling fan neutral wire; and

a junction box being made in the shape of a rectangular box connected to said mounting plate to hold said control circuit assembly inside said junction box, said junction box comprising two pins at two diagonal front corners thereof fitted into two corresponding round holes on said mounting plate, two round holes at the other two diagonal front corners thereof respectively connected to the other two round holes on said mounting plate by screws, a plurality of wire holes on the back thereof, through which said lighting fixture neutral wire, said hot wire and said ceiling fan neutral wire are respectively inserted.
