Supporting members are arranged on the front panel to support an elastic member which can hold the switch under the elastic deformation of the elastic member. One support member is arranged one side of the opening in the front panel and another support member is arranged on the opposite side of the opening. The elastic member includes a pair of longitudinal webs adapted to engage with the lateral flap portions of the switch and at least one transverse web connecting the longitudinal webs together. The elastic member has tongues for engaging with the support member.

Abstract: A power director enables a user to apply power through one or more power outlets via one or more switches to a cluster of electrical devices, for example, the components of a desk top computer system. A typical computer system may have a CPU chassis, monitor, printer, CD-ROM and a document scanner each of which may have its own power line cord. The housing of the current power director has internal storage spaces or bays for coiling the excess portions of the power cords of the various computer components to eliminate the tangled mess associated with such systems. The electrical outlets are located in a component bay within the housing separate from but adjacent to the line cord storage bay to be accessible to the plugs of the line cords of the electrical devices sought to be controlled. The component bay contains a first printed circuit board (PCB) which carries the electrical outlets and a second PCB that contains an electrical surge protection circuit, a fault isolation circuit and the switches.

Abstract: A device for change-over switching of electric motors has a housing and two safety disconnecting switch systems positioned adjacently to one another in the housing. A cover is slidably connected to the housing so as to cover one of the safety disconnecting switch systems respectively. A fuse holder with fuses is detachably connected to the housing. Each one of the safety disconnecting switch systems has receiving elements for receiving the fuses. The safety disconnecting switch systems are electrically connected to one another such that upon insertion of the fuses into the receiving elements of one of safety disconnecting switch systems the electric motors rotate in one rotational direction and that upon insertion of the fuses into the receiving elements of the other one of the safety disconnecting switch systems the electric motors rotate in the other rotational direction.

Abstract: 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.

Abstract: A rigid insulating shield has tabs at a lower end inserted in slots in a case and a press-in fastener at an upper end inserted within a hole in a switch base assembly for securing said shield within the case. A handle pullout has a large flange extending over the shield when inserted in the switch base assembly to prevent removal or displacement of the shield while the handle pullout is inserted in an ON position of the switch. The flange is sufficiently large to block direct access to termination means on the switch base assembly when the shield is removed and the handle pullout is inserted in the switch ON position.

The interface circuit includes a first circuit section and a second circuit section. The first circuit section is located adjacent the back wall of the enclosure and behind the second circuit section, and the second circuit section includes communication means for allowing an operator at the front of the enclosure to communicate with the circuit breakers. This arrangement minimizes heat in the back of the enclosure, provides control and monitoring functions at the front of the enclosure and allows room for additional circuitry in the back of the enclosure.
