SU756506A1 - Push-button switch - Google Patents

Description

The invention relates to electrical engineering and can be used in various radio devices, mainly in telephone switches of small capacity for 5 switching electrical circuits and providing connections between subscribers.

Known pushbuttons are known that contain spring-loaded buttons arranged in a row on 10 common bases, one of which is a reset button, the rods of all buttons are made with pins and are connected to each other by a fixing ruler with grooves, 5 made perpendicular to its long sides and intended to be inserted into them button pins in the working position, contact elements and blocking unit £ 1], M. . 20

However, these switches have limited functionality.

The purpose of the invention is to expand the functionality due to the inclusion of any two buttons with a lock from accidentally pressing the third, as well as, if necessary, the inclusion of any number of buttons. thirty

This goal is achieved by the fact that in the push-button switch in the fixing ruler there are three other buttons also designed for inserting — in them, pins of buttons in the working position, a groove, two of these grooves angled to the long sides of the fixing ruler, and the third one interconnects all the grooves, while the rods of each button are set so that their pins are located opposite the extreme groove located at an angle to the long sides of the fixing ruler.

FIG. 1 shows a button switch assembly) in FIG. 2 - the same, side view; in fig. 3 is a view A of FIG. 2; in fig. 4 - various positions of the fixing ruler.

The pushbutton switch contains a base .1, on which are placed contact groups 2, fixing a ruler 3, rods 4 pushbutton switches, buttons 5 switches, reset buttons 6, buttons, 7 blocking exceptions, screws 8, spring 9 for removing the locking ruler with grooves into the original position, lever 10, spring-loaded stops 11 for fixing push-button switches, plate

12 reset switches. On the rods of the push-button switches are springs 13 to return the switch buttons to their original position. On the stock of the reset button is the tooth 14 fixing the slats. The locking bar 3 has grooves 15, perpendicular to its long sides, grooves 16 and 17 angled to its long sides, and groove 18 connecting grooves 15, 16 and 17.

Push button switch works as follows.

When you press the button 5, the protrusion on the rod 4 enters the inclined groove 17 of the fixing ruler 3 and retracts it to the second position, combining the other grooves 16 with the pins on the rods of the buttons 5 of the other switches. The tooth 14 fixes the fixing ruler in position II. Buttons 5 are held in the pressed position by spring-loaded lugs 11.

When any second button is pressed, the rake, with grooves, is again moved and fixed by the tooth 14 in the Sh position. When you try to press any third button, the pin on the button stem rests against the fixing ruler, thereby excluding the possibility of activating the third button.

When you press the button 7 to exclude blocking using the lever 10, the locking bar 3 moves to the fourth position, while aligning the groove 15 with the pins on the stem of the button 5, which makes it possible to turn on any number of buttons. In this case, tooth 14 locks the rail into position. IV.

When the reset button 6 is pressed, the tooth 14 releases the rail, the pin on the stem of the button 6 lifts the reset plate of the switches, which in turn releases the rods of the buttons 5 and 7 from fixing them with the stops 11. Next, the locking bar 3 and the buttons 5, 6 and 7 under the action of springs 9 and 13 return to the starting position.

Claims (1)

Claim A push button switch containing spring-loaded buttons located on the common base, one of which is a reset button, the rods of all buttons are made with pins and are interconnected by a fixing ruler With grooves made perpendicular to its long sides and intended for inserting the pins of buttons into them position, contact elements and blocking node, characterized in that, in order to extend the functionality, three others are also made in the fixing ruler, also intended for within them of the buttons in the operating position the pins of the slot, wherein two of the grooves are arranged at an angle to the long sides of the fixing line, and the third of which connects all the slots, the rods of each button are set so that their pins are different. meshes opposite to the extreme groove located at an angle to the long sides of the fixing ruler.
