Abstract
The invention discloses a locking indicating device of a changeover switch. The locking indicating device comprises a bracket, a microswitch base which is arranged on the bracket, a microswitch which is arranged below the microswitch base, a cover plate, a handle locking component, a changeover transmission component and a display component. The changeover transmission component is mounted on the bracket. The cover plate is fixed on the bracket through a vertical column and is located above the changeover transmission component. The handle locking component is mounted above the cover plate. Three gears of the changeover transmission component cooperate with one another for finishing changeover between a main power supply and an auxiliary power supply. Furthermore a straight rack of the display component engages with the gear and is used for displaying the state of the switch. Furthermore a handle can touch the microswitch through operation, thereby representing a manual state; simultaneously a locking board is extracted from the handle, and locking can be performed. The locking board of the locking indicating device of the changeover switch cannot be opened on the condition that the changeover switch is not totally in a double-separation position, and a locking action cannot be finished, thereby improving safety of the device.
