Abstract

A cabinet assembly comprises a cabinet, a main wiring board provided with a control circuit and disposed within the cabinet, switches for controlling the control circuit, and keys for operating the switches, capable of being pushed from outside the cabinet. To eliminate restrictions placed by the keys and a light emitting diode for indicating actions of the control circuit on the design of the cabinet, to simplify the construction of the cabinet assembly and to facilitate cabinet assembly assembling work, the switches and the light emitting element are mounted on the main wiring board, the keys are formed and disposed so that the key top of each key form a portion of the external shape of the cabinet, each key is provided integrally with an actuating rod for operating the corresponding switch, and the light emitted by the light emitting element is transmitted by a light transmitting member to a portion of the wall of the cabinet or to the key top of the pushed key.

A cabinet assembly comprising:

a cabinet;
a main wiring board provided with a control circuit and disposed within the cabinet;
switches for switching and adjusting the control circuit, mounted on the main wiring board;
a light emitting element for indicating actions of the control circuit, mounted on the main wiring board;
and
keys capable of being pushed from outside the cabinet and each of said keys having a key top forming a portion of the external shape of the cabinet and a working arm integrally formed with and substantially perpendicular to the key top;
wherein each of said keys is provided integrally with an actuating rod for operating the corresponding switch when the respective key is pushed by flexure of the working arm such that the direction of the pressure applied to the respective key is parallel to the direction of flexure of the working arm, and the light emitted by the light emitting element is transmitted by a light transmitting member directly to the key top of the respective key to illuminate the key top.
