Description

II

Изобретение относитс к электро1технике и может быть использовано в коммутаторах цепей управлени в печатном исполнении.The invention relates to electrical engineering and can be used in printed circuit control switches.

Один из известных кнопочных выключателей содержит корпус, неподвижные контакты, дy ooбpaзнyю контактную пластину и приводной элемент в виде вилки, установленный с возможностью взаимодействи с упом нутой пластиной D3. Выключатель имеет ограниченные коммутационные возможности .One of the known pushbutton switches comprises a housing, fixed contacts, a dividing contact plate and a drive element in the form of a plug, installed with the possibility of interaction with said plate D3. The switch has limited switching capabilities.

Наиболее близким по технической сущности к за вленному вл етс кнопочный выключатель, содержащий неподвижные контакты, дугообразную упругую контактную пластину, закрепленную в середине, и взаимодействующую с ней по образующей цилиндра, проход щей через точку закреплени , приводной элемент в виде -вилки. Однако и этот выключатель сложен, нет возможности выполнить его непосредственно на печатной плате, а провода присоедин ютс к нему навесным монтажом 2 .The closest to the claimed by technical essence is a push-button switch containing fixed contacts, an arcuate elastic contact plate fixed in the middle and interacting with it along a generator cylinder passing through the anchor point, a drive element in the form of a fork. However, this switch is also complex, it is not possible to execute it directly on the printed circuit board, and the wires are attached to it by means of a mounted installation 2.

Целью изобретени вл етс упрощение конструкции.The aim of the invention is to simplify the design.

Цель достигаетс за счет того, что в кнопочном выключателе, .содержащем неподвижные контакты, дугообразную упругую контактную пластину, закрепленную в середине, приводной элемент в виде вилки, имеющей возможность взаимодействи с упом нутой дугообразной упругой контактной пластиной, при котором она измен ет свое положение так, что ее образующа занимает положение перпендикул рное ее первоначальному положению , и при этом замыкаютс соответ/ствующие пары неподвижных контактов.The goal is achieved due to the fact that in a pushbutton switch, containing fixed contacts, an arcuate elastic contact plate fixed in the middle, a drive element in the form of a plug, having the ability to interact with the arcuate elastic contact plate, in which it changes its position as that its forming occupies a position perpendicular to its original position, and at the same time the corresponding / fixed pairs of fixed contacts are closed.

Claims

Moreover, the conductors of the printed circuit board, which is made with holes for insertion of the plug, are used as fixed contacts, and the arcuate elastic contact plate is fixed to the specified printed circuit board. FIG. 1 shows an axonometric image of a board with pushbutton switches, where the leftmost switch is pressed; in fig. 2 - PCB, bottom view in FIG. 3 - OTHER version of the PCB under the switch. A pushbutton switch (Fig. 1) is located on a section of the printed circuit board 1 (in Fig. 2 and Fig. 3 is circled in dashed lines), which has a mounting hole 2, two guide holes 3 and four fixed contacts C in the form of printed tracks, lying on the sides of the square K of the board 1 on the side of the fixed contacts i is attached to an elastic arcuate contact plate 5 so that it contacts with the fixed contacts of the tracks lying on opposite sides of the square. The plate -5 to the board 1 is attached with a rivet 6 passing through the holes In its middle and in the board 2, on the other side of the board, a drive element 7 is inserted into the guide holes 3, made in the form of a plug, the ends of which rest against the arcuate plate 5 at the points lying on the ends of the generatrix passing through the middle plate 5 The switch operates as follows: by moving the pre-electrode element 7, it overcomes the rigidity of the arcuate contact plate 5. which is sharply bent to form an arc-shaped surface rotated 90, and short-circuits another pair of fixed contacts k. When external forces are removed, the contact plate 34 also abruptly returns to its original position. The push-button switch assembled on the board (Fig. 3) has two working positions (one fixed), and the signal from contact 1 of plate 5 is picked up in two directions from the moving contacts A lying on opposite sides of the square. Claims: Pushbutton switch comprising fixed contacts, an arcuate elastic contact plate fixed in the middle, an actuating element in the form of a plug, capable of interacting with the said arcuate elastic contact plate at which it changes its position so that its forming position perpendicular to its original position, with the corresponding pairs of fixed contacts being closed, characterized in that, in order to simplify its construction, 8 Visible contacts: used are conductors of a printed circuit board, which is made with holes for insertion of the plug, and an arcuate elastic contact plate is attached to the specified printed circuit board.
