Изобретение относитс к электро- технике и предназначено дл коммутации посто нного и переменного токов.The invention relates to electrical engineering and is intended for switching DC and AC currents.

Цель изобретени - повышение надежности работы переключател .The purpose of the invention is to increase the reliability of the switch.

На фиг.1 схематически изображен кнопочный переключатель, продольный разрез; на фиг.2 - разрез Ае-А на фиг. 1 .1 shows a schematic of a push button switch, a longitudinal section; FIG. 2 shows a section Ae-A in FIG. one .

Переключатель содержит корпус 1, расположенные в нем.герконы 2, два идентичных посто нных магн ита 3, установленных вплотную друг к другу на штоках 4 таким образом, что оси их намагниченности параллельны друг другу , причем посто нные магниты 3 ориентированы полюсами в одну сторону.The switch comprises a housing 1 located in the reed switches 2, two identical constant magnets 3, mounted close to each other on the rods 4 in such a way that the axes of their magnetization are parallel to each other, with the permanent magnets 3 oriented by poles in one direction.

Under the influence of the rocker arm b with the tip 9 and the ejection force created by my mutual magnetic field by the magnet 3, the lower magnet 3 moves upwards, while the right part of the tip 9 pulls up to it and goes switch reed switches.

Claims

Invention Formula

A pushbutton switch, comprising a housing, reed switches located in it, are two parallel parallel to each other on the rods of identical permanent magnets oriented with the same poles in the same direction, and these rods are installed inside the housing from one of its ends, ferromagnetic plates, each of which is bonded to one 25 53 rods and a corresponding magnet, distinguished by the fact that, in order to ensure reliable operation, it

The tips 8 and 9 are placed on the yoke 6 with the ability to interact with the poles of the permanent magnets 3. The yoke 6 is located relative to the permanent magnets 3 on the side of the body opposite to the end in which the rods 4 are mounted, and the indicated axis 7 of rotation of the rocker arm 6 is set perpendicularly longitudinal axis of the hull.

The device works as follows.

In the initial state due to

fixing the extreme positions of the magnets.

Invention Formula

fixing the extreme positions of the magnets.

A pushbutton switch, comprising a housing, reed switches located therein, two parallel permanently mounted to each other on the rods of identical permanent magnets oriented by the same poles to one side, and these rods are installed inside the housing from one of its ends, two ferromagnetic plates, each of which is bonded with one 53 rods and a corresponding magnet, characterized in that, in order to improve reliability of operation, it

equipped with mounted on the axis of the yoke 1

scrap with two installed on it

the repulsive force, the firing of 40 triangular ferrules from the ferrules when the like poles of the permanent magnets 3 interact and the forces of the magnets interacting with the tips 8 and 9, one of the magnets 3 is in the upper position, and the rods are different, the axis of the rotationally magnetic material is different the rocker is located relative to the permanent magnets from the end of Kopiryca opposite to the end, in which there is a mouthpiece in the lower one. In this case there will be a replacement - you are the reed switches 2, located opposite the lower magnet 3.

When pressing the rod 4 of the magnet 3, which is in the upper position, the latter moves downwards and, by triangular ferro-tips, rods, the indicated axis of the rotating-magnetic material of the rocker is located relative to the permanent magnets from the end of the Kopiryca opposite to the end face, in which

Neither the rocker arm is installed perpendicular to the longitudinal axis of the switch body, and each short-circuit triangular handpieces are installed with the possibility of interaction with the respective policies of permanent magnets.
