Description

Technical Field

[0002] A switch status indicator is an electrical measuring instrument that is mainly used to display the switch status in a circuit. When using circuits or other complex electrical equipment, a switch status indicator allows users to easily and quickly determine the status of switches (such as circuit breakers, contactors, etc.) to ensure that the circuit is in a normal and safe working state. Therefore, a switch status indicator is an indispensable part of the circuit system.

[0003] For example, the patent with application number 202223469487.7 discloses a switch status display with a protective structure, including a fixing mechanism, the fixing mechanism includes an upper frame, a wiring port is provided in the middle of the upper end of the upper frame, a wire clamping plate is hingedly provided inside the wiring port near the upper end, a control mechanism is slidably provided inside the fixing mechanism near the rear side, the control mechanism includes a lower frame, a display panel is provided through the middle of the front end of the lower frame, and a control panel is embedded at the bottom of the front end of the lower frame. In the utility model, the internally arranged control mechanism can slide to the inside of the fixing mechanism through the sliding groove and the sliding bar, which facilitates the installation of the control mechanism, and a cooling fan and dustproof nets are provided inside, which improve the internal air flow rate, thereby increasing the heat dissipation efficiency inside the display, and improving the service life of the internal circuit board, and finally realizing the protection function of the display.

[0004] In the above patent, the display dissipates heat through the internal cooling fan and the dustproof nets on both sides. Although the internal air flow rate is increased, thereby increasing the heat dissipation efficiency inside the display, when the switch state display is used in a relatively humid environment, untreated humid gas directly enters the interior of the display, causing damage and rust to the electronic components inside the display, and in severe cases, it may cause short circuit and fire.
