DE1028663B - Toggle switch, especially for vehicles, with three switch positions and one zero position - Google Patents

Description

GERMAN

The invention relates to a toggle switch with three switch positions and a zero or switch-off position of the rocker arm carrying the current bridge, the contact of which is at an obtuse angle run to the longitudinal axis of the rocker arm. There is a particular need for switches of this type in motor vehicles, where there is z. B. is important, blind in one direction the interior lighting of the Car or the parking light, in the other direction the lighting on the dashboard or about turning on the windshield wipers so that the driver has his full attention of the road can turn to. There is also a need for this, either in the former case the light intensity the dashboard lighting or, in the other case, the speed of movement lower the windscreen wiper if it has been set to a maximum speed beforehand, although it is also desirable. the resistance value for the change in light intensity or else the speed of the wiper can be increased at will within two fixed end positions. change.

In a known, also having four switch positions of the buddy and the switch handle The switch lever moves only by about 50 ° and is in the "Off" end position vertical, in the other end position inclined to the switch mounting plate. One of them slides Buddy of the Kümpelpaares, which is arranged at an obtuse angle to the longitudinal axis of the rocker arm handle is, via a common power supply rail and the other buddy via three consecutive Fixed contacts with corresponding turns of one below the base arranged resistor are connected. Since the switch handle is only within a very small Can be adjusted in the angular range, the differences in inclination are Difficult to assess for the individual switch positions. So you can probably use the two end positions of the toggle lever blindly, but leaves the setting of the various switch positions behind Doubt and uncertainty when using it.

In the case of a switch with four switch positions of the rocker arm or contact dome, one is vertical Central position of the rocker arm not available, which is necessary for the blind feasibility of the switch position according to the variety of switching tasks assigned to the switch is desired, namely as follows: that it is assigned the zero position of the switch. Only then can the switch be switched on in one or both directions as a deviation from the vertical central position undoubtedly to be seen or met blindly, and the toggle switch,

especially for vehicles,

with three switch positions

and a zero position

When changing gears, the driver is not distracted from observing the road.

According to the invention, this need is satisfied in that the detent for the currentless position of the toggle lever out of the vertical center line of the switch base in the direction of the one detent contact relocated and the handle part of the rocker arm carrying the contact caps in this switching position is bent perpendicular to the switch mounting plate, while the next, facing away from the end contact Detent contact is approximately the same distance from the vertical center line as the detent and In the free frontal space of the base pit obtained in this way, another contact for another .Switching task is provided, preferably in the form of a connected to this contact, of the Kontaktkümpel η to be touched resistance track. This measure thus becomes a symmetrical one Design of the switch housing or base achieved what for the desired central attachment of the switch is of considerable importance. Although the notches corresponding to the zero position of the switch for the Buddies are moved out of the vertical axis of symmetry, the rocker arm itself is in this position perpendicular to the dashboard supporting the switch, and the switched-on state of the switch is in in each case clearly recognizable or perceptible as a deviation from this position. On the switch side, on the contacts for changing the light intensity or for changing the speed

resistance of the windshield wiper, a resistance track can be connected to each of these two contacts, which run parallel to each other and are touched by the two contact bumps, so that thus a practically stepless regulation is brought about. The fact that the resistor is also protected in the base pit, i.e. inside the switch.

A preferred embodiment of the invention is shown in the drawing.

Fig. 1 shows a section along the plane of movement of the rocker arm,

Fig. 2 is a section along the line II-II of Fig. 1 and

3 shows an interior view of the switch base with a built-in control element.

In the pit of the switch base 1, which is made of insulating material, the two opposite notches 2 for the central position of the symmetry axis of the base leading through the bearing axis 12 are offset on the vertical walls and to the left of it (Fig. I) the notches 3 for the one switching direction, on the right the notches 4 for the other switching direction, which has at least two switching positions. The metallic contacts carrying the notches 3 and 4 have the connection terminals 5 and 6, respectively. Resistance tracks 7, 8, which run parallel to the walls of the base pit, are connected to the two contacts 4, 6 here. The toggle lever 9, 10 is angled so that its outer leg 9 is perpendicular to the switch mounting plate, not shown, when the lower toggle leg 11, which encloses an obtuse angle, and the contact dome 13 with its two contact projections 14, 15 penetrate the notches 2, 2. If the lever handle 10 is moved to the right from this vertical position (FIG. 1), the buddy 13, 14, 15 comes into conductive contact with the notches 3, and one switching task is carried out. On the other hand, if the handle 10 is pivoted to the left from this central position 4 », the contact dome 13, 14, 15 comes into conductive contact with the notches 4 for the other switching task, in which there is either a change in the light intensity of a dashboard or car lighting or but the change in the speed of a windshield wiper matters. In this case, the rocker arm can be moved continuously, with the two resistors 7, 8 being switched on. On the switch base 1, an upper part 16, open at the top, is placed with a cap 17 and ^{shares with the base ^ '1} ' in a known manner by hollow rivets 18 or the like.

It is readily apparent that in such a configuration of the toggle switch, the Al · "deviations from the vertical electroless central position towards one or the other direction: blind switch position can be felt by the driver.
