Problems solved by technology

Although this solution solves the problem of status information feedback, it will increase the space occupied by the control panel or the installation disk due to the need to occupy additional space on the control panel, which will inevitably lead to the expansion of the installation disk and heavy waste of materials.
[0004] Now, in order to reduce the space occupied by the control panel, the indicator light device is often integrated with the switch body in the prior art. When there are multiple display gears, such an arrangement will occupy most of the space on the panel and cannot be installed. Indicator light showing current status

Embodiment 1

[0023] figure 1 It is a structural schematic diagram of a changeover switch with an indicator light in Embodiment 1 of the present invention.

[0024] Such as figure 1 As shown, in this embodiment, the changeover switch 100 with an indicator light is installed on a control panel not shown in the figure, and is used for gear control of corresponding equipment (not shown in the figure). The changeover switch with indicator light 100 includes a switch body 10 , an indicator light device 20 , a gear adjustment device 20 and a power supply device not shown in the figure.

[0025] figure 2 It is an exploded view of the indicator light type transfer switch in Embodiment 1 of the present invention.

[0026] Such as figure 2 As shown, the switch body 10 includes: four coaxially stacked contact layers 11 and a rotatable switching shaft 12 .

[0027] The four contact layers 11 are used to connect multiple devices (not shown in the figure) according to a predetermined combined conn...

Embodiment 2

[0051] In the second embodiment, the same structures as those in the first embodiment are given the same symbols, and the same descriptions are omitted.

[0052] Figure 4 It is an exploded view of the indicator light type transfer switch in the second embodiment of the present invention; Figure 5 It is an exploded view of the indicator light device in the second embodiment of the present invention.

Abstract

The invention aims at providing an indicator lamp holder, an indicator lamp device including the same and a change-over switch with an indicator lamp. The indicator lamp holder installed at an indicator lamp device comprises a housing, at least one lamp holder circuit board, an indicator lamp unit, a voltage-limiting element, and a cover plate. A penetrating hole is formed in the middle part of the housing; and at least one through hole is formed near the penetrating hole. The at least lamp holder circuit board is installed in the through hole; and a lamp holder pin for conduction of the lamp holder circuit board and an indicator lamp device is arranged at the back of the at least lamp holder circuit board. The indicator lamp unit arranged on the lamp holder circuit board is used for indicating a current control state. The voltage-limiting element is arranged on the lamp holder circuit board; and when a voltage is larger than a preset reference voltage, the indicator lamp unit is in conduction. The cover plat arranged at the housing cooperates with the housing and is used for accommodating the circuit board, the indicator lamp unit, and the voltage-limiting element.

Description

technical field [0001] The invention relates to an indicator light base, an indicator light device comprising the indicator light base and a changeover switch with an indicator light. Background technique [0002] The multi-position transfer switch with indicator light is a switch that can be used for two or more power sources or load conversion connections and controls the operation of various devices. It has been widely used in daily life and industrial production. Such as: power station, track change station, high-speed rail locomotive, subway locomotive, ship. The multi-position switch with indicator lights includes a plurality of contact layers and a rotatable switching shaft connecting each contact layer. The rotatable switching shaft is driven to rotate by rotating the handle, thereby realizing the opening and closing of the corresponding equipment. When installing a multi-position switch with indicator lights, the handle is installed on the outside of the control pa...
