Abstract

A push-button switch comprising a button, a housing within which a pusher with protrusions on the side walls is located, a spring, one end of which abuts against the housing and the other end into the pusher, two pairs of switching contacts, each of which includes one movable spring and one fixed contacts, located on the side of the protrusions, which act on the movable spring contacts, characterized in that along the body are made ribs for securing these contacts, and the button and pusher are made at the same time.

Description

The utility model relates to electrical engineering and can be used for switching nodes of various electrical products, for example, lighting and ventilation in X (two devices). A switch is known, which contains at least one button module with a protrusion designed to influence a contact spring plate, one end of which is secured in the housing, and the other is in contact with a fixed contact, and a spring, one end of which abuts the housing and the other is the stem housing l. m of such a switch is the presence of two buttons, two switching modules and accessories for them, which complicates the switch.The closest in technical essence to the proposed push button switch is a switching element, C1 containing control BUTTON, housing, a pusher located in it with protrusions for switching movable spring contacts , a spring, one end of which abuts against the housing, and the other end into the pusher 2. The disadvantage of such a switching element is the technological complexity I have contacts in the housing coma utatsionnogo element, the presence of additional components, utsravlyayuschaya button and the pusher are designed as two separate parts - all this complicates the design of the switching element in its assembly and increases the complexity of the proposed purpose of the pushbutton is to simplify the design-time reduction in its manufacturing and assembly

contains a button, a housing, inside which a pusher with protrusions on the side walls is dispersed, a spring, 01 the end of which rests on the 4 housing, and the second - on the pusher, two pairs of switching contacts, each of which includes one movable spring and one fixed contacts, which are located on the side protrusions that act on the moving contacts, the contiguous contacts, ribs are made into the distance of the body to secure the specified contacts, and the button and pusher are made at the same time.

The push button switch is shown in FIGSF: general view and side view The push button switch contains a housing I with a cover 2 At the corners of the housing I there is an appendix with pins 3, and on the cover 2 there are holes 4, which include pins 3 and fasten the cover 2 to the housing I. Inside the housing I there are pusher 5 with projections 6.7 on the side walls, two pairs of switching contacts 8.9 and 10.11 located on the side of projections 6.7. Each pair of spring contacts includes one fixed contact 8.10 and one movable spring contact 8.11 Spring contacts 9.11 located with one hundred the protrusion of the protrusion, the pusher 5 "Contacts 8,9,10,11 are fixed between the ribs 12,13,14,15 and the walls of the housing I There is also a khfuzhina 16 in the housing, one end of which abuts against the housing I, and the second end - into the pusher housing 5 The pusher 5 is made integral with the 17 "button

The push-button switch operates as follows In the initial state, as shown in the figure, one pair of contacts 8.9 is in the open state, the second pair of contacts 10.11 is in the closed state U) And this movable spring contact II is pressed by the protrusion 7 of the pusher 5 to the contact 10, by pressing the button 17, the protrusion 7 pushes 5 releases (the movable contact II is released and it moves away from the contact 10, - the contacts 10.11 open, and the protrusion 6 of the pusher 5 makes the movable contact 9 to the fixed contact 8, the contacts 8.9 are closed releasing pr Folders 17 the spring 16 returns the plunger 5c button 17 to the initial position IP original position and spring contacts are 9.11 "

To obtain other options for contact pairs, for example, two normally closed or two normally open pairs, it is necessary to change the position of the protrusions on the pusher 5 without changing the design of the push button switch.

Thus, the use of ribs in the push-button switch, between which the switching contacts are installed and fastened, as well as the construction of the pusher along with the button, made it possible to reduce the number of parts, shorten the manufacturing time and speed up the assembly of the push-button (xgo of the switch, even if the switch contacts fail) the design allows u) to protect and replace the main parts of the push button switch

At present, 10 samples of push-button switches of the proposed design have been manufactured and tested, which have confirmed the reliability of the work. Currently, preparations are underway for serial production of push-button switches of the proposed design
