Abstract

SWITCHING DEVICE OF A SLIDER TYPE, comprising a housing, a slider with grooves and a protrusion and L-shaped terminals, each of which has a rounded protrusion at the free end, a rounded protrusion of one of the conclusions, and a rounded protrusion of another output has the possibility of interacting with the first output, wherein the slider block protrudes against another conclusion, characterized in that. in order to expand its functionality, it is provided with a third L-shaped output, and the rounded protrusion of the second output has a shape that also allows the third output to interact.

Description

Inoculation refers to electrical engineering and is intended for use in a computer as coding devices, regulators: .para.1etrov in memory devices, in ACS, measuring and testing aini ;;) a: -rs, 15 communication systems, c) in { ) medical equipment for domestic use, and so-called.

A slider switch is known, comprising a housing with grooves, a slider with a rod, a contact and a spring mounted on the rod, and non-moving contacts fixed on the housing, with the ends of the contact spring inserted into the slots of the housing 1.

This device has a complex structure.

The most technical to the invention in terms of technical support is the switching device of the THiia slide, containing the body, the slider with the slots and the protrusion: CONCLUSIONS are L-shaped, each of them has a rounded n on the free end; ledge The rounded protrusion of one iLi 1,1vod is designed to be fixed into a paspl julzuna, and the rounded protrusion of a druio 1i.:; The ode has the ability to interact: 5 1 with the first pin, if this is the protrusion iio.iiiyHa 11 is matched into another pin 2.

This design has limited functionality, as it is; -.-: it cannot be used when the installation is disabled.

The purpose of the invention is the expansion of the 11k Fupk 11a, 1y1th capabilities.

For this purpose, the switching device, of a zono type, contains a corpus, a; 1zun with grooves and a protrusion, and draws a G-mode;: a second form, each of which has a rounded height of 1, .1eNNNP the protrusion of one of the;

Nedpaziachen length of fixation in the grooves of the Iolsu-1. the other one has the ability to interact with the first iibiiio.iOM, the protrusion no; i3yna abuts against:, the output, supplies a third BbHw.ioM L-shaped, and the round protrusion liToporo of the output has () the form, ensuring the possibility of interaction also by the third output.

Mafi1 1 shows the device in the initial position; pa fi1. 2 - the device in the unsupported p.yuzhenin.

A half-type switching device contains a corus, which includes oboy.mu 1, is a junction1, it has a box-shaped structure made of an electrically insulating material, and a base 2 fixed in it and having a T-shaped symmetrical design, a turntable.the wall 3 of which is. d, 1I of lcpi of one contact rpyiHibi from another (fie is shown) with a flat part, the grooves with prismatic yi-jiy6,: ienH / M 4,

a contact group consisting of 5-7 L-shaped pins made of spring-loaded current-carrying material.

E5 pin 5 and. Has a rounded protrusion 8, pin 6 ends with a rounded BE with mortar 9, with its upper part under the action of elastic forces tightly pressed to pin 5, and the lower part is directed in the opposite direction.

Pin 7 is located under pin 6, with a gap between their working surfaces. In the vertical part, pins 5-7 have corrugations 10 located in grooves with a prismatic recess 4 so that they, with their rounded part, fit snugly to the side walls of the recess, prevent flux from flowing into the switch body and at the same time firmly fix pins 5-7 in the required direction. mom position.

There are also sliders 11, each of which has its protrusions 12. serving for controlling the device, are located in the grooves of the base 2. The slider is in its lower part and has a shaped surface in the form of two grooves 13 and 14 and a protrusion 15 of a rounded shape.

The rounded protrusion 8 of the pin 5 in its original position is in the groove 13, and the protrusion 15 is in contact with the top inclined plane 6 of the pin.

The switch works as follows.

In the initial position, the rounded protrusion 8 c) of the water supply 6 is located in the prize of a mathematical groove 13 of the slider 11 and, under the action of elastic forces, tightly presses the latter to the upper horizontal wall of the base.

The rounded protrusion of the second terminal 6 of the node by the action of elastic forces is tightly pressed to the terminal 5, providing a reliable electrical contact between the contacting surfaces of the terminals 5 and 6.

When translating the slider 11 from the floor1 (; |; and) U of the protrusion 12 to the leftmost position (Fig. 2), its rounded off protrusion 15 slides along the inclined surface of output 6, the upper part of which is iodine to the top of output 5, removes it from the latter, with the rounded pin 8 output 5 times. placed in the prismatic groove 14 of the slide 11, fixing it securely in this position, with this lower round rounded part 9 of the terminal 6 and tightly pressing the horizontal output surface 7 on the working copacter, secured Reliable electrical contact between in Output 6 and output 7.

We offer my switch. It can be made multi-pole depending on the number of sockets in the holder.

In addition, when moving the working part of output 5 from the prismatic groove 13 into

groove 14 causes the contacting part to slip along the working surface of the output 7, and when the slider 11 moves to its original position, slippage occurs at the point of contact of the working surfaces of the lower part of the output 6 and output 7, resulting in a self-cleaning of the contacting surfaces, increasing the reliability of the contact.
