Patent number: 5436799Abstract: A modular switching-element block which comprises at least one base body having plug-in locations for switching elements, such as electrical switches, and is fitted with a base body which is split into a plurality of base-body modules which can be plugged into one another. In comparison with a common base body, this arrangement makes possible greater variability of the number of plug-in locations, with respect to freely selectable special fits with switching elements, and reduces the advance-provision cost for a standard fit.Type: GrantFiled: December 16, 1994Date of Patent: July 25, 1995Assignee: Mercedes-Benz AGInventors: Karl-Heinz Krieg, Siegfried Klink, Uwe Manzke, Michael Schulcz

Patent number: 5347427Abstract: 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.Type: GrantFiled: March 1, 1993Date of Patent: September 13, 1994Assignee: Mitsubishi Denki Kabushiki KaishaInventor: Hirotaka Kinoshita

Patent number: 5272591Abstract: The present invention provides a cover for an exposed bus bar attached to an electrical control device having a contour mounting surface for circuit interrupters. The cover includes a generally planar body member having sufficient size to substantially cover the exposed bus bar. The cover includes means for securing the body to the device so that the position of the body prevents contact between the bus bar and a person's finger or equipment particularly when an individual circuit interrupter is mounted to the device.Type: GrantFiled: September 30, 1992Date of Patent: December 21, 1993Assignee: Square D CompanyInventors: Randall L.
