Description

(54) SWITCH

one

The invention relates to electrical engineering, in particular, to switching devices that can be used in information input control devices;

A switch is known, comprising a housing, contact elements, a control element and a reciprocating spring mechanism 1.

However, the switch has limited switching capabilities.

Also known switch, comprising a housing, contact groups with pressure springs and key (2.

Disadvantages switch - limit. , t5. Low functionality, design complexity and inconvenience in operation.

The purpose of the invention is to expand the functionality, design 20 and improve convenience. in operation.

The goal is achieved by the fact that in a switch containing jcopnyc, contact groups with two spring springs and a key, the body is made with a protrusion on which the key is pivotally mounted, contact groups with pressure springs are fixed around the body's perimeter

Yes, the pressure spring presses the key in such a way that the key has the ability to interact with one or two contact groups through the corresponding pressure springs.

The key is square-shaped, its front surface has separate sections according to the number of switching inclusions, the middle section is made flat and is parallel to the landing plane of the switch, and the remaining sections are made with a slope, while the sections of the key that are affected by two contact groups are made with an incline from the inclination of areas of the key acting on one contact group.

and figure 1 shows the front surface of the key; 2 is a section A-A in FIG. one; in fig. 3 - section bb in Fig.2; FIG. 4 is a diagram of the movement of the marker on the ID of the formational field of the video control CMogram.

The switch includes a housing 1 with a protrusion 2; along the perimeter of the protrusion, contact groups 3-6 are installed in the form of microswitches. On the ledge 2 corps. 1, the key is mounted 7, pressed against

each contact group 3-6 is pressed by springs 8. The key 7 is square shaped, on the front surface of which plots are marked. The middle section 9 is made flat and parallel to the crawler plane of the switch, and the remaining sections are made with a slope. The inclination of the sections 10-13 of the key affecting one contact group is different from the inclination of the sections 14-17 of the key acting on two contact groups.

On the information field 18, the position of the marker is designated by numbers 19-21.

The device works as follows.

When an external force P is applied to the key, for example, section 10, the key 7 is rotated on the hinge and, compressing the pressure spring B, switches the contacts of the contact group 3. After the external force stops, the key returns to its original position under the action of the named spring 8. When an external force is applied successively to the sections 1113, the contacts of the contact groups 4-6 are switched, respectively. When an external force P is applied to the sections 14-17 in succession, the contacts of the contact groups Zi4, 4 and 5, 5 and 6, and BiZ will switch, respectively.

A switch control for moving the marker from the 19-slot cell to the cell 20 in the information field 18 of the video monitor device can be carried out in the following directions.

When an external force is applied to section 10, the marker is vertically mixed upward to position 21. Then, applying force to section 13, the marker moves to the right in memory cell 20. When force is applied

The marker section 17 moves along the shortest route from the memory cell 19 to the cell 20.

Claims (2)

1. A switch comprising a housing, contact groups with pressure springs and a key, characterized in that, in order to expand the functionality and simplify the construction, the housing is made with a protrusion on which a key is pivotally mounted, contact groups with pressure (and springs are fixed along the perimeter the body protrusion, and each compression spring presses the key so that the said key has the ability to interact with one or two contact groups through the corresponding pressure spring. 2. The switch according to claim 1, characterized in that, in order to improve ease of operation, the key is square in shape, its front surface has separate sections according to the number of switching inclusions, the middle section is flat and parallel to the landing plane of the switch, and the remaining sections are made with an inclination, while the key sections, acting on two contact groups, are made with an inclination different from the inclination of the key areas acting on one contact group.
