jjjl ektri s before C ehalt arrangement

Me invention relates to an electric fJchaltanordnung, and has as its object to provide such a iJchaltanordnung in functional T I'Orrn.

The electrical container assembly according to the invention is characterized by a switch actuation mechanism which is selectively movable into one of three positions, a first and a second contact arm on which the actuation mechanism engages and which with their longer axes lie essentially in parallel planes, a first and a second port associated with the respective contact arms, a first hinge about which the harvesting contact arm is movable by the actuating mechanism, and second and third hinge about which the second arm is selectively movable by the actuating mechanism, one of which Arrangement isb provided that in a first position of the actuating mechanism the first and the second arm contact the first and the second connection, in a second position of the actuating mechanism the first arm is in contact with the first connection and a contact between the second arm and the second connection interrupted and in a third position of the actuating mechanism, contact between the two arms and their associated terminals is interrupted.

The .Erfindung is in the following to Ίίαηύ. an exemplary embodiment explained in more detail with reference to the drawing. In the drawing; are:

The switching arrangement t / eisb a Lockel 10 through which connections 11, 12 extend. Stops 13, 14 are attached to the cockel 10 ″ and lie in line with the connections 11, 12, see above that the lines between the terminal 11 and the stop 13 and awisehen dera connection'-! 12 and the stop 1 / j. essentially parallel lie. An upright tab 15 is on the base 10 between the connection 11 and the stop 15 attached, uii a joint to form a contact arm 16. Two additional upright ones Tabs 17 »18, which are identical to tab 15, are attached to the ijockel 10 between the contact 12 and the stop 14, to form two joints on which another contact arm is selectively 19 can attack in a manner to be described. the Tab 17 and tab 15 are in one plane, the one on the right Angle to the direction of extension of the longer axes of the arms 16 and 19 lie. The contact arms 16, 19 each carry contact elements, which are intended to rest on the connections 11, 12, and also carry abutments 22, 23 »the jareils to rest against the stops 13 »14 are provided. The arms 16, 19 are with their longer axes pivotable in parallel planes.

A switch operating mechanism 24 is selectively one of three positions 24a, 24b, 24c movable and engages the arms 16 and 19 on. Axial movement of the arms 16 and I9 is through respective Gate projections 25, 26 prevented from being attached to the associated Create joints.

In operation, electrical linergy is applied to tabs I5 »18, which can also be connected to each other. If the actuation

gungsineehaniciaus 24 is in position 24a, the arms 16, 19 are pushed to the right as shown, xvaä. If there is no contact with your respective terminals 11, 12, when the mechanism 24 is changed to position 24b, the arm 16 is pushed to the left to make contact with the terminal 11 and the arm 19 pivots about the hinge VJ . In the position 24b, the mechanism 24 lies between the joints Vj ₁ 18, and the arm 19 is therefore held essentially parallel to the base 10. When the mechanism moves to position 24c, aria 16 is not affected and arm 19 pivots about hinge 18 to engage connector 12.

The switching arrangement thus enables one or both to be closed two circuits through an iJcha-ltmechanism with three switch positions.

The switching arrangement described above looks best to control the lighting system of a motor vehicle for a two-pole switch.
