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.
