Abstract

The invention relates to electrical engineering and can be used for panels mounted on control and signaling elements. The purpose of the invention is to reduce the size, weight and improve operating conditions. The light lines 3 and 4 of the switch are separated by an opaque sheath 5. The thin-walled cylinder 6 is made of an opaque material. In QiW7A, the linder has an opaque jumper 7. Through windows 10 are located opposite the lamp 8. The lamp 8 is connected to the switching node 13 and provides a glow to the ring 14. The lamp 9 is electrically connected to the lamp 8 and the control unit I5. Circle 16 illuminates lamp 9. Light guide 3 is the control button. The moving contacts 17 of the switching node are fixed on the control button. The fixed contacts of the switching node are connected to the control unit. When the control button is pressed, the switching node is activated. The lamp 8 lights up. The operation of the control unit 15 causes the lamp 9 to glow. Ring 14 signals the operator's influence on the control button. The luminous circle 16 signals a change in the state of the control unit. In order to increase the reflection coefficient, a specular one was applied to the end face 11 of the conical shape of the light guide 3. coating. 1 з.п, ф-л, 3 Il. yu (Oh yu NI od sp

Description

I1246 I SI

The invention relates to electrodischarge from the blink of a mirror on the connection of a cable to the blink of a cable on

mutation devices, and can be used for telemechanics panels saturated with control and signaling elements.

The aim of the invention is to reduce the size and weight, as well as to improve the operating conditions, by ensuring uniform illumination of the outer light guide.

1 schematically shows a switch; figure 2 - section aa in figure 1 on an enlarged scale; Fig. 3 shows possible variants of the light indication in different states of the control button.

The switch includes a housing 1, a button springed relative to the housing 1 by an elastic element 2, and made in the form of an external light guide 3 with an axial cavity in which the internal light guide 4 is located. The light pipes 3 and 4 are separated by an opaque sheath 5. The device also contains a thin-walled cylinder 6 , made of opaque material, fixed at one end, in the housing "and the other - placed in the axial cavity of the light guide 3. The cylinder 6 is provided with an opaque jumper 7, section conductive lamps 8 and 9, the illumination. Opposite of the illumination lamp 8 on the side surface of the cylinder 6 along the perimeter there are through windows 10 that allow the passage of light radiation to the external light guide 3, the lower end 11 of which is made conical to ensure that the light radiation is directed upwards along the light guide axis (shown by arrows Fig. 1). In order to increase the reflection coefficient, a mirror coating may be applied to the end face 11, and to prevent its violation, a washer 12 is installed under the supporting surface of the elastic element 2, the lamp 8 is connected with a comma the mutation node 13 and provides the illumination of the ring 14, and the lamp 9 is electrically connected to the lamp 8 and to the control unit 15 and provides the illumination of the circle 16. On the control button the moving contacts 17 of the switching node are fixed, and the fixed contacts of the switching node are connected to the unit 15 controls

When the control button is pressed, the switching node is triggered, causing the lamp B to glow and the state of the block 15 to change. The control of the control block 15 causes the lamp 9 to illuminate. The light of the ring 14 indicates the operator’s influence on the control button, the glowing circle 16 indicates a change in state control unit 15 acting on the control object. In the switch, light induction is provided as follows (Fig. 3). A - the initial state of the device, the absence of a signaling about the impact on the button, the absence of a signaling about the change in the state of the control unit, B - the control signal is given, but the state of the control unit has not changed, the presence of the signaling only about the operator's influence on the button, C - the control signal filed, the state of the control unit has changed, the presence of the signaling of the operator’s impact on the button, the presence of the signaling that the state of the control unit of the operator has changed, D - the operator has not given a control signal, but the state block change, the presence of a signal about a spontaneous change in the state of the control unit.

When using the self-return button and the trigger in the switching node 13 in the switch, to return the device to its original state, simply press the control button again.
