Brief Description of the Drawings

In FIG. 1 shows the design of the remote control - view from the side opposite the panel.

In FIG. 2 shows a section aa in FIG. 1 (increased).

Utility Model Implementation

The utility model can be implemented in the following design.

The control panel includes a housing 1 made of an insulating material, consisting of two parts 2 and 3, interconnected by screws or screws 4. Part 3 contains a panel with control elements in the form of buttons 5 of switches made of insulating material, the number of which is determined, based on the necessary functionality. The control elements can be made in the form of keys, a joystick handle, etc., or as a combination of these elements. Buttons for convenience are separated from each other by transverse ribs 6.

The control panel also contains a control unit, which in the push-button control panel contains switches with movable electrical contacts 7 and fixed electrical contacts 8.

The movable electrical contacts 7 are flat conductive plates with electric contact elements fixed at the ends, oriented across the housing and mounted together with contact springs 9 in transverse rectangular openings 10 made in a central cross section of a central part of each of the buttons 5.

Fixed electrical contacts 8 are fixed on one side to tires 11 attached to insets 12 made of electrical insulation material, mounted on metal plates 13.

On the other hand, each fixed electrical contact 8 is made in the form of a metal bracket with a threaded hole on one bent end and an electrical contact element 14 on the other. At the bent end of each bracket, a metal plate 15 is installed with an opening in which a clamping screw 16 is located, screwed into the threaded hole at one bent end of the bracket. Moreover, each bracket is installed at its ends in the grooves of the insert 12, and in each insert two brackets are installed.

In each insert 12, a narrow longitudinal groove 17 is made, in which a beam 19 is mounted on the axis 18. The ends of the axis 18 protruding beyond the side surfaces of the beam 19 are located in the transverse grooves of the insert, the walls of which prevent the beam from moving in the longitudinal direction. The movement of the beam in the transverse direction is prevented by the bottom surface of the groove 17 and the surface of the metal plate 13.

Thus, the insert 12, the plate 13, the beam 19, the tire 11 and two pairs of fixed electrical contacts 8, mounted on the bus 11 and the insert 12, form a separate module.

There can be several such modules in the case.

Each button 5 has an internal cavity in which a return spring 20 is partially placed.

The control circuit breaker is located in the lower part of the housing and is made in the form of a conventional push-button switch, in which the button 21 has a rectangular cross-sectional shape and a protrusion 22. The button 21 has a rectangular groove in which the contact spring 23 is arranged and made in the form of an elongated metal plate movable electrical contact 24, installed with the possibility of coming into contact with electrical contact elements 26 of fixed electrical contacts 27, mounted on the housing 28 of the circuit breaker management.

A rectangular hole is made in the housing 28 of the control circuit breaker, in which a return spring 29 and button 21 are located. The housing 28 of the control circuit breaker is fixed in the housing 1 of the control panel.

The key brand 30 has a working surface, a supporting surface 31 and a guide surface 32. The corresponding supporting and guide surfaces are made in the housing 1 of the control panel.

The working surface of the key mark contains an inclined surface 33, designed to interact with the surface of the protrusion 22 of the button of the control circuit breaker, and the protrusion 34, designed to fix the key mark from spontaneous loss.

The electrical control circuit is a conductor 35, through which an electric current from an external source is supplied to one of the stationary electrical contacts 27 of the control circuit breaker, a conductor 9, by which an electric current is drawn from another stationary electrical contact 27 of the control circuit breaker to the buses 11, on which on the lower side (Fig. 1) fixed and fixed electrical contact elements 14, and conductors 36, through which electric current is removed from the fixed electric pins 8.

The supply of conductors to the control panel is carried out through the input 37 fixed in the housing 1, having a tubular shape.

The control panel operates as follows.

In the initial position in all switches, the contacts are in the open state. In this case, the brand key is removed from the housing 1 of the control panel and when pressing any buttons 5 of the switches in their electrical circuit there is no current.

The entry of the key-mark into contact with the housing 1 of the control panel is accompanied by its movement along the supporting and guide surfaces, during the translational movement of the key-mark its inclined surface 33 comes into contact with the surface of the protrusion 22 of the button 21 of the control circuit breaker, and upon further movement transfers moving the button 21 in the perpendicular direction. In this case, along with the button 21, the contact spring 23 and the movable electrical contact 25 move to contact with the stationary electrical contacts 27 and the contact spring 29 is compressed. With further movement of the key-mark, the button moves, deforming the contact spring 23. Then, after passing the top 34 of the working surface of the key mark past the apex 22 of the button 21 of the control circuit breaker button 21 moves in the opposite direction until the stop of the protrusion 22 into the surface of the key mark located behind the protrusion 34 A spring 23 holds the movable electrical contact 25 in contact with the stationary electrical contact 27. In this position, the key mark is securely fixed by the protrusion 22 of the button 21 and prevents the remote control from falling out of the housing 1.

When the button 5 of the control circuit switch is pressed through the electric control circuit, the current is transmitted to the conductor 36 connected to the fixed electrical contact of the corresponding external electrical device, while under the action of button 5, the rocker 19 rotates, blocking the movement of the adjacent button 5 located at the other end module.

In this regard, in one module there are two control circuit breakers that provide opposite movements of the executive link of the external device mechanism.
