Description

"Switch for executing several functions"

The subject of the invention is a switch according to claim I ₃ by which several key positions are to be enabled on each side when the rocker is actuated.

In many areas it is necessary to carry out several switching operations with one switch to be able to perform. Known switches that allow multiple switching operations are the so-called rotary switches, which are in different Positions can be brought where they each have a different one Cause switching action. However, rotary switches are awkward to use, so that they are not advantageous for certain applications.

Should, for example, in a radio receiver that has a number Has light-emitting elements with which the set transmitter is displayed, a station search at different speeds are provided, it is much more comfortable for the user of the radio receiver if he means the different speeds Set the button to be pressed instead of using a rotary knob adjustment can.

An electrical switch with a contact rocker is already known, which is operated with the help of a rocker arm or rocker arm, whose Swivel bearing for the purpose of forming a middle switch-on position from the There are rails of two connection contacts, only one of which is direct voltage is applied, and its tilted position for a second switch-on position and are used for a zero position (DE-AS 11 10 718). Disadvantageous is with this switch, however, that apart from the zero position only a right and a left switch position is realized, i.e. it it is not possible to carry out a station search with this switch, which has two different running speeds both to the left and to the right.

It is also an electrical switch with one of at least two Housing parts existing switch housing known, which has a pivotable between two end positions rocker arm, with a locking and / or reset element is provided which acts on the rocker arm (DE-OS 26 36 632). This switch also does not allow two different ones Search speeds in two different directions.

Finally, a contact device for controlling is also encapsulated electromagnetic switching devices with the help of the outside of the housing the encapsulation arranged handles have been proposed, wherein the handle as a flat finger swivel sunk into the housing cover is formed (AT-PS 1 98 815). This contact device

An embodiment of the invention is shown in the drawing and is described in more detail below. It shows

FIG. 3 shows the rocker switch according to FIG. 2 in a second switching position;

Figure 4 is an exploded view of the rocker switch.

In the figure 1, a rocker 1 is shown in a horizontal position, the is connected to a rotor 3 via a pin 2. This rotor 3 has a cylindrical projection 4, which is a stationary stop disk 5 opposite. To the pin 2 two contact springs 6, 7 are wrapped in such a way that they encompass the pin 2 and then, their Align spring arms 8, 9, 10, 11 crossing to the right and left at the top.

A stop 12, 13 is provided on both sides of the rotor 3.

The stop disk 5, on the outer edge of which the spring arms 10, 11 rest, has in its center a rectangular projection 14, on both sides of which the spring arms 8, 9 rest.

The operation of the switch of the invention is the following: If you press the left side of the rocker 1 shown in · Figure 1 with a certain force, the rocker one initially assumes the position shown in the figure. The spring arm 8 is carried along by the projection 4 and is finally pressed against the spring arm 10. The resistance which is opposed to the spring arm 8 by the spring arm 10 can be felt with the finger. As soon as the two spring arms 8 and 10 come into contact with one another, the first electrical contact is closed. The electrical potential connections necessary for a current flow are not shown for the sake of simplicity. However, one can imagine that a first potential is applied to the spring arm 8 and a second potential is applied to the spring arm 10. In addition, it is not absolutely necessary for the electrical circuit to be triggered by the spring arms themselves. It is sufficient if an electrical connection is established in the position in which a stop can be felt.

Now the left side of rocker 1 is down with increased force pressed, the rocker 1 assumes the position shown in FIG. the two spring arms are now carried along until the rotor 3 hits the Stop 12 hits. Another contact is triggered by the contact between the rotor 3 and the stop.

A corresponding sequence of functions can also be achieved by means of graduated pressure to reach the right side of the rocker 1, so that with the switch according to the invention a total of four functions with five switch positions can be executed. When the rocker 1 is released, the rocker 1 automatically returns to the starting position shown in FIG.

FIG. 4 shows an exploded view of the rocker according to the invention shown, which can be installed in a housing 20. One recognizes here again the contact springs 6 and 7, as well as the pin 2 with the rotor 3 and the Projection 4. Between the contact springs 6 and 7 is an additional one Disc to be seen, which facilitates the relative displaceability of the contact springs 6 and 7. Below the flag 3 are a pressure spring 22 and a contact axis 23 are provided. Below is one Circuit board 24 with conductor tracks on which the flag 3 grinds. The position of the rotor 3 thus determines which electrical contact is closed will. The circuit board 24 is secured by means of a securing ring 25.

Numerous technical problems can be solved with the switch. Bai for example it is possible in a radio receiver with the mentioned station search two different search speeds and directions to be switched on. Light up at the first stop on the left the light-emitting diodes of a diode chain with a first frequency in the left direction one after the other, while the same diodes at the second stop light up at a second frequency. If the rocker 2 is printed on the right side, the diode chain lights up in a corresponding way, only that the lighting up now does not go from right to left, but from runs left to right.
