A connection for two items of installation equipment lined up beside each other with their end or broad sides against each other, in particular line-protection circuit breakers, residual current circuit breakers and the like, whose housings are each formed from two shell-shaped housing parts. The connecting element has an approximately cylindrical base body with a first outer diameter onto which, on both sides, two radially springy spreading arms projecting axially in opposite directions are integrally molded. The outside diameter of the spreading arms is smaller than the outside diameter of the base body and free ends of the spreading arms have radially protruding lugs which, when assembled, latch in behind protrusions on the housings of the items of installation equipment located beside each other and to be connected by the connecting element.

A component mounting bracket system for mounting a component on a mounting wall having a pair of support apertures and a hole. The system comprises an upper bracket and a lower bracket mountable on a component. The upper bracket has a mounting aperture and the lower bracket includes a main portion and a pair of bracket arms attached to the main portion. The bracket arms are positioned in a spaced relationship and have a lower edge with a mounting notch opening downwardly for engaging a lower edge of one of the support apertures. The notches permit a relatively small degree of pivot movement of the lower bracket and the component mounted thereto with respect to the mounting wall while supporting the component in a position substantially adjacent to the mounting wall. The mounting aperture of the upper bracket forms a loop structure for looping over a fastener protruding from the hole in the mounting wall for hanging the component from the fastener.

A power transfer device adapted for interconnection with the electrical system of a building includes a cabinet, a set of switches mounted to the cabinet, and a first set of wires for connecting the switches to an electrical distribution panel associated with the building electrical system. The power transfer device includes a terminal compartment associated with the cabinet, a set of power input terminals located within the terminal compartment, and a cover removably connected to the cabinet for alternatively preventing and permitting access to the terminal compartment. The cover is provided with an optional meter arrangement adapted to be interconnected with the power input terminals for selectively measuring levels of power provided from a source of auxiliary power connected to the power input terminals.

The present invention provides a method for mounting an element on a chassis. The method comprises several steps. The element is stopped from sliding in at least one direction when the element is placed on the surface of the chassis. A clip is pivotably connected to the chassis. The clip pivots between first and second position holding the element in place in the second position. The clip is locked in the second position.

An apparatus is proposed for supporting a device, the apparatus having at least one foot with an undercut. The apparatus has a depression for accepting the foot and an engaging mechanism with a projection. When the device is moved toward the apparatus, the undercut presses against the projection and thereby displaces the engaging mechanism. As soon as an upper edge of the undercut moves below a lower edge of the projection, the engaging mechanism moves back toward its starting position and thereby engages the undercut of the foot.

A switch mounting structure for fixing integrally, securely and firmly a rotary connector, a switch base, and a bracket mounted to a steering column of a vehicle, by an easy single operation. The switch mounting structure has first frame members 3d having opening portions 3c formed therein provided on a fixing case 3 of a rotary connector 1, and second frame members 7c having opening portions 7b formed therein provided on a bracket 7 of the rotary connector 1. The first frame members 3d are engaged with first elastic engaging portions 5e in first engaging portions 5a provided in a base 5 of a switch 4 by a simple single action. Similarly, the second frame members 7c are engaged with second elastic engaging portions 5h in second engaging portions 5c by a simple single action.
摘要:
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.

A one piece mount for mounting switches is disclosed. The mount includes a face plate provided with an aperture in which a push button switch or a key operated switch may be located. A support bracket is located on the rear face of the face plate being formed as one piece with the plate and is provided with holes in which push button switches may be mounted. In one version of the mount a raised portion is provided on the rear face being formed as one piece with the face plate and the support bracket wherein the aperture extends through the raised portion. In use, this version of the mount is provided with a key operated lock cylinder mounted in the aperture and having a cam arm pivotally mounted on the rear face of the lock cylinder. At least one push button switch may be mounted in the support bracket with the relative positioning of the aperture and the support bracket being such that when the key is moved, the cam arm, which moves with the key, activates the push button switch mounted in the support bracket. In another version of the mount there is provided a bracket for mounting the mount on the edge of a recess in a wall, the bracket located adjacent one end of the face plate on the rear face. A key activated locking bar also for engaging the edge of a recess in a wall for locking the mount into the door or wall is located at the other end of the plate.

A switch module includes a plurality of individual switches (2), each having a base (3), which are arranged next to one another in a common holder on the same plane. The bases (3) are embedded in a common base (4) produced by encapsulating in a plastic. The bases (3) can be fixed to one another before encapsulating by means of plug-in connecting parts. The common base (4) has fastening claws (5) arranged on both sides, the talon ends of which are designed as enlargements (6). The sealing surface (17) has no mold-parting flash.

A control panel supports and positions interchangeable subunit electronic devices and provides a neat and uniform outwardly facing surface. When subunit electronic devices are disconnected from the control panel, cover plates extend and conform to the uniform outwardly facing surface. Hinged support members "lock" in an over center position to rigidly support each cover plate. Electrical connectors protruding from each subunit electronic device "unlock" the hinged support members from the over center position when the subunit electronic device is urged toward the cover plate.
