Toggle switch

Summary of the invention

The subject of the invention is a toggle switch in which to close and break contacts
a contact rocker by an actuation device
a pin serving as a pivot bearing. is tilted, wherein the rocker performs a lateral sliding movement along the contact surface of the fixed terminal pin touched by it.

The invention relates to a toggle switch with a housing provided with a recess on which a Actuating quality is mounted tiltable.

The object on which the invention is based exists

in designing such a toggle switch so that generated during the switching process a sliding movement between the contacts to be brought into and out of engagement will.

This is achieved according to the invention in that a number of arranged in a certain orientation in the housing Contacts and at least one contact rocker with one resting on at least one contact elongated part and another part abutting the actuating member are provided; that one the contacts is provided with a pivot bearing which has a predetermined triangular cross-section has and on which the rocker by the actuator is held in a pivoting system; that the rocker is angled in a certain way with such Play on the swivel bearing resting ■ bearing section has that it in the initial tilting movement lifted from one of the aforementioned contacts and attached to another contact can be brought and that the storage section is moved away from the apex of the pivot bearing when the tilting movement continues and the rocker a movement transverse to the other contact in the plane of those in contact Contacts.

The toggle switch designated as a whole by 10 has a lower housing part provided with a recess 19 11, which is partially covered by a protective cap 12. On a pen-shaped pouch 14 is a tiltable actuator 13 between the triangular side walls 15 at the top,

of the lower housing part 11 is mounted. The recess 19 is delimited by these two side walls 15i 16 and the two end walls 17, 18.

Several connecting pins 21, 21 'and 21' 'aligned with one another and arranged parallel to them Terminal pins 22, 22 'and 22' extend through the bottom wall 20 of the housing part 11.

The connecting pins 21 'and 22' are as in Tig. shown with a knife-edge pivot bearing 23 is provided, the apex angle of which is preferably substantially 90 °.

The switch shown has two contact rockers 24- and 25 · Both contact rockers, one of which is in 9 are formed similarly. The rocker 24 shown in this figure has a with a Contact 26 provided end and is bent back at its other end at 27. The bent back yielding one Section 28 has an angled nose 29 at its free end. The middle part of the contact rocker has a V-shaped bearing section 30, the apex angle of which is greater than that of the Pivot bearing 23 and preferably 125 is. Of the V-shaped bearing section 30 rests on the pivot bearing 23 of the pin 21 'or the pin 22' in the manner shown in FIG.

As shown in Fig. 9, the bearing portion 30 extends laterally beyond the edges of the rocker so that it is on the protruding part of one of the side

walls 15 ″ or 16 and a middle partition 30 ′ (see FIG. 6). As can be seen from FIG The actuating member 13 is provided on its underside 31 with a central block-shaped extension 32, which has side edges 33 and triangular ^{blade-shaped bearing parts 3 2} I-, 35, the apex lines of which are offset from one another in the horizontal direction (Fig. 7) The central lug 32 also has a central support portion with a substantially flat lower surface which lies below the plane of the side edges 33 (Fig. 7).

The end walls 17 and 18 of the housing part 11 have Projections 37 and 38, which are provided with recesses 39 for receiving the two ends of a leaf spring 40 are provided. When the actuator 13 is between the side walls 15 and 16 is used, is the flat lower surface of the central support section 36 on the spring 40 (Fig. 2) and holds the switching element in its neutral, inoperative position. When you press the switch to close a Circuit via individual connection pins and one of the rockers, the actuator 13 can either (seen in Fig. 2 and 3) clockwise or counterclockwise about the shaft 14 tilted will.

In Fig. 3, the actuator 13 is clockwise tilted and with this movement has the jirei-

angular bearing part 34 to the flexible section 28 of the seesaw 24 in such a way that the Line of the force acting on section 28 extends to the opposite side of pivot bearing 23 extends and the rocker 24 · tilts about this bearing into the position shown. At the same time, the Bearing part 35 moves further along the bent-back section of the rocker 25 and holds it in its not actuated position. When the rocker 24 is in the tilted position (FIG. 3), its contact 26 rests on the contact 4-1 of the pin 22, while the other end of the rocker out of contact with the contact 4-2 of pin 22 ".

A through, the design of the V / ippe 24 · and des Pivot bearing 23 of the pin 22 'achieved additional advantage consists in the basis of FIG. 3 and 4- explained mode of operation, in which a sliding movement between the rocker contact 26 and the contact 4-1 of the pin 22 takes place.

When tilting the actuator 13 in the sense of Clockwise, the triangular bearing part 34 becomes full Surface contact with the nose 29 located at the end of the flexible section 28 of the rocker 24 come and move the rocker on the pivot bearing 23 to the side. This is achieved by the Pivot bearing 23, as already mentioned ;, an apex angle of about 90 ° and the bearing section 30 of the rocker has an angle of 125. This angular The difference between these two components allows the aforementioned lateral sliding movement

movement of the seesaw. This sliding movement has an effect
very inexpensive because they cause the accumulation of. Sparks and the like caused contamination between the contacts is prevented. .

If the actuating member is tilted in the opposite direction, the other rocker 25 will tilt about its pivot bearing 23 when the bearing part 35 rests against the flexible section of the rocker 25.

The switch described is a preferred one
Exemplary embodiment of the invention. However, it is apparent to the person skilled in the art that modifications of this embodiment are possible within the scope of the inventive concept. ·
