DE2532092B2 - Steering column switch with switching element molded onto the switching part - Google Patents

Description

The invention relates to a steering column switch with a switching lever mounted in a switching part, the a contact is applied, as well as contacts and mating contacts for switching the individual functions (DE-AS 20 22 436).

The object of the invention is to provide such a steering column switch, particularly with a view to a To improve the arrangement of the contact pairs for easier assembly.

This is made possible according to the invention in that all contacts and mating contacts on one the bottom of the steering column switch housing forming contact plate are mounted, and that for Actuation of at least one pair of contacts, a switching element formed on the switching part is provided.

Thus, all contact-making elements are arranged on the contact plate and can be used as a built-in unit be pre-assembled.

Advantageous embodiments of the invention can be found in the subclaims.

An embodiment of the invention is explained in more detail below with reference to the drawings. It shows

1 shows a longitudinal section through a steering column switch,

Fig. 2 shows a section along the line H-II in Fi g. 1, d. H. a plan view of the Konlaktplatte with the housing removed, and

FIG. 3 shows a section along the line III-III in FIG. 2.

In one consisting of two side walls 2, a rear wall 3 and a cover part 4, one-piece Housing 1 is a shaft part 5 around a vertical axis 6 and in this switch part 5 a switch lever 7 around a horizontal fastening bolt 8 is pivotably mounted. In the end area 9 of the shift lever 7 is a spring-loaded locking element 10, which is located on an approximately horizontally in a switching element switching curve 12 slides along, provided. About this switching curve 12, the pivoting movement of the switching part 5 for the Direction indicator controlled. The switching element 11 in turn leads one through the further switching curve 13

ίο controlled vertical movement that effects the light switching the end. For this purpose, it has a latching device 15 on the outside 14.

A contact equipped with all the necessary contacts is used as the bottom of the housing 1.

Plate 16. For the direction of travel is a pair of contacts 17, consisting of a U-shaped bent Leaf spring 18, connected to + 49a and two leaf springs 19, between holding blocks 22 under pretension built-in. The leaf springs 19 are in contact

Stop blocks 24. The pair of contacts 17 is actuated by an eccentric formed on the switching part 5 Switching element 25.

The further contacts 26 and 27 are designed as flat strips lying in the longitudinal direction

·? ■> mounted like a rocker and attached to the contact plate 16 molded bridges 28 held against the force of compression springs 29. Serves as a second abutment a transverse, electrically conductive, rigidly attached connection plate 31. The attachment is made with the

JO exit high beam 56a. The two contacts 26 and 27 lie in guide grooves 32 and are actuated by the contact piece 11 via actuating pins 33 and 34 applied. The position shown is the low beam position (Fig. 1). +56 (main light switch) is over

j5 the cable 35, the contact 26, contact rivets 36 and the Connection plate 31 connected to 56a (exit high beam).

When the switching piece 11 is actuated, the contact 26 initially hits due to the lever ratios

«O the mating contact 56b (low beam), the high beam contact still being closed until, when you press it again, it opens and only the low beam contact is closed.
If the contact piece 11 is deflected even further,

■ »5 wherein the actuating pin 34 on a not shown Drainage slope on the contact piece 11 runs off, so that the contact 26 is not pressed further down can, the contact 27 is on the mating contact +30 and closes the circuit of +30 via the

w contact 27, the cable 37 and the connecting plate 31 Re 56a (high beam - headlight flasher with main light switch switched off).

Instead of the drainage slope, it is also possible to use actuating pins of different lengths. the

Deflection of the contact piece 11 is limited by a stop 38 downwards.

The application of the contact plate and the contact attachment shown is of course not only limited to that described switching functions limited.
