Description

The invention relates to electrical engineering, in particular, to remote monitoring and control, intended for remote signaling of changes in the state of an object and can be used, for example, in small-sized mnemonic schemes of production processors as a symbol of switching equipment.

The purpose of the invention is to reduce the size of the device.

The fixed contacts of the 2 contacts of the switch indicator, the conductive axis 4, the angle 13, the LED 15, the angle 14, the conductive sleeve 9 and the housing 1 are fixed. The LED 15 lights up, symbolizing the discrepancy between the state of the still non-working object and the position of the handle indicator switch, symbolizing the operation of the pump on the mimic. When executing a command, i.e. switching on the pump, the contact of the object breaks the alarm circuit. The LED goes out. The state of the pump now corresponds to the position of the handle on the mimic diagram. I

You are 2 and 3, pressed against the conductive axis 4 of the switching and latching mechanism. On the conductive axis there are segments 5 of insulating material and segments 6 of conductive material that are movable contacts. The moving contacts, which are closed with fixed contacts 2, are electrically connected to the conductive axis 4, and the remaining moving contacts, which are closed to the stationary KOHTaKTaMJi 3, are electrically isolated from the conducting axis 4, which is at one end installed in the holder 7 and the other in the hole 8 of the housing 1 by means of a conductive sleeve 9, insulated with a gasket 10 from the conductive axis 4. The conductive sleeve 9 is wrapped around the housing 1 by a leaf spring 11 with a spring clip 12. The handle is designed to be insulated from each other. each other and rigidly connected respectively with the ends of the conductive axis 4 and the conductive sleeve 9 angles 13 and 14, encircling the light indication element — an LED 15 electrically connected with the latter. The number of fixed contacts 3 is set depending on the control circuit in which the indicator switch is used.

The device works as follows.

 When a control signal is applied to turn on the object, i.e. when the indicator knob is rotated across the line of the mimic diagram, the control current flows independently of the external control circuit, for example, through the circuit through one of the two axis-following switch indicators, which are not involved in the switching circuit of the fixed contacts pump 3, through the movable contact 6 and another fixed contact 3. The signaling current passes through the contact of the object, closed when the object is turned on, through the second of the two fixed contacts 2 of the switch indicator, the conductive axis 4, Corner 13, LED 15, Corner 14, conductive sleeve 9 and housing 1.

to the external control circuit and alarm. To control an object, such as a pump, the operator manually turns the switch indicator knob. In this case, the command receives an on / off command to the object, and a signal to change the state of the object from the object to the indicator. When a control signal is applied to turn on the pump, i.e. when you turn the knob of the switch indicator, for example, along the line of the mimic circuit, the control current passes through one of the two fixed contacts 5 3, the SUPPORT contact 6, and the other fixed contact 3. The signal current passes through the contact of the object, closed when the object is turned on, through one of the fixed

contacts 2 of the switch-indicator, conductive axis 4, corner 13, LED 15, corner 14, conductive sleeve 9 and housing 1. LED 15 illuminates, symbolizing the discrepancy between the state of the still non-working object and the position of the switch indicator that symbolizes operation pump on the mnemonic. When executing a command, i.e. switching on the pump, the contact of the object breaks the alarm circuit. The LED goes out.

those. switching off the pump, the contact of the object breaks the alarm circuit. The LED goes out. Now the off state of the pump corresponds to the position of the handle on the mimic diagram.

If a spontaneous shutdown occurs during pump operation, for example, when power is lost, the circuit through the object's contact, closed when the state is on, pump through the fixed contact 2 of the switch indicator, corresponding to the position of the handle of the pump being turned on, and then through the conductive axis 4, angle 13, light-emitting diode 15, angle 14, the conductive sleeve 9, and the housing 1 passing current. The LED illuminates, symbolizing this change in pump state. By turning the handle, the fixed contact 2 of the switch indicator breaks the alarm circuit. The LED goes out. The position of the handle is adapted to the state of the pump.
