DE1031869B - Device for locking the switch positions on toggle or rocker switches - Google Patents

Description

The invention relates to a device for locking the switch positions in the case of tilt or Rocker switches with linearly moved back and forth Switching element and a slide influenced by the actuating element, the S and the spring acting directly on the switching element tensions the spring after the switching element has been released the switching element by a laterally arranged locking piece that acts directly on the switching element suddenly brings it into the other switching position in which it is held by the locking piece.

In a known switch of this type, the slide is first of all over the tensioned switching spring the SchaltoTgan moves slowly until the under spring pressure standing locking pieces are moved outward by a cam-shaped projection of the switching element. Only now, after overcoming the locking pieces, does the force of the tensioned switching spring take effect, and the switching element is suddenly brought into the other end position. The switching element leads so here always up to the overcoming of the locking pieces through the apex of the cam-shaped Approach a slow movement, only the final movement of the switching element takes place suddenly. Furthermore, the switching element is not locked in the end positions.

In another known switch, a slide moved by the actuating member tensions by means of a Bolt a spring. The bolt sits on a lever that is rotated around a fixed point at the same time. at the further movement of the slide is rotated by this a locking member about a point and thereby released a nose of a second lever, which is connected to the former via said spring stands. Now the second lever is rotated around its bearing point by the tensioned spring and the switching element thereby suddenly moved into the other position. This switch consists of many individual parts and has a complicated structure. With such a switch, the attachment of the locking piece makes the construction of the same even more cumbersome and ultimately results in such a height of the switch, that the use of the same as a flush switch is excluded.

The invention is based on a switch with the initially features described and aims to create a switch in which, in a simple manner, so without much effort, a momentary switching is achieved. The switch according to the invention has with regard to of the known switch described in the first place has the advantage of being carried out from the beginning sudden movement of the switching element. With regard to the switch mentioned in the second position becomes a device through the arrangement according to the invention

simple structure and a low construction achieved. As a result of the small number of individual parts and the nature of their interaction, the switch according to the invention has a long service life high operational reliability.

According to the invention, the locking piece is tiltable about a point and is controlled by the slide in such a way that immediately λόπι locking piece depending on the switching direction of the path of the switching member to the relevant stationary mating contact is released and the switching member is locked in the other direction. An expedient embodiment of the subject of the invention is that the slide is provided with lateral lugs which slide along the inner wall of the base recess on the one hand and on the stepped or curved slide of the movably mounted locking piece on the other hand. The locking piece here has a centrally arranged pin which is guided in an elongated hole which is arranged in the base part and extends transversely to the switching direction.

The locking piece is with one or more springs against the slide or against the Switching element pressed that the switching element abruptly on the opposite side when the switching process is triggered locked and a contact pressure required for proper contact between the Switching element and the busbar is generated. The switching element is advantageously bolt-shaped formed, and its end faces cooperate with the mating contacts. Instead of pressure contacts however, sliding contacts of a known type can also be used.

On the switch base 1, the bridge 2 with the actuator 3 and the terminals 4a to 4c are attached. The switch base 1 has a recess 5 in which all switchgear parts are housed. The actuator 3 is loosely coupled to the slide 6. As soon as the slide 6 is moved, the spring 7 is tensioned. The lateral lugs 8 of the slide 6 slide along the inner wall 9 of the base recess 5, while the lugs 10 control a locking piece 11 provided with a stepped or curved slide. When the slide 6 has covered part of its way and the spring 7 has a correspondingly high bias, the locking piece 11, which is under the action of the springs 12, is pushed aside by the lugs 10. Thereby, the W ^r ec of the bolz en form aqueous switching member 13, 14 are used whose end surfaces as contact surfaces, released, so that the switching member 13 suddenly hits the fixed mating contact 19 and 21 respectively. At the same time, the locking piece 11 performs a tilting movement and locks the path between the abandoned stationary mating contact 19 or 21 and the corresponding end face of the switching element 13. The locking ends 15 of the locking piece 11 serve as a stop for the switching element 13; that is, these hold the switching element 13 in its position once it has been assumed until the spring 7 is pretensioned to such an extent that when the switching element 13 is unlocked it is able to move it abruptly into the other end position.

The locking piece 11 can be pivoted with its centrally arranged pin 16 in the elongated hole 17 (Fig. 3) and is mounted against the slide 6 or against the switching element 13 with the aid of the two springs 12 printed. The springs 12 on the one hand have the task of the switching element 13 abruptly when the switching process is triggered with the aid of the locking piece 11 to block on the opposite side and on the other hand a necessary for a perfect contact To generate contact pressure between the switching element 13 and the busbar 18. A flawless contact print in the axial direction of the switching member 13 is achieved in that the spring 7 with a corresponding Bias is built into the slide 6 so that after triggering the switching process the spring 7 can only relax as far as the required contact pressure requires.

In the switch position shown in Figures 2 and 3 the electrical connection between the terminals 4 a and 4 & over the except for the Bottom of the base recess 5 reaching busbar 18, the switching element 13 adjacent to this, and the elastic strip 20 provided with the mating contact 19 is produced.

In the opposite switch position, the current runs from the connection terminal 4a via the busbar 18, the switching element 13 and the likewise elastically designed, provided with the mating contact 21 Current ribbon 22 to terminal 4c.

Instead of the pressure contacts 19 and 21, sliding contacts of a known type can also be used Use that expediently come within the base recess 5 similar to the busbar 18 are arranged. In this case, the switch can especially in the axial direction of the switching member 13 are made much smaller.
