Technical Field
The utility model relates to the technical field of switches, specifically be an aviation plug micro-gap switch.
Background
At present, the micro switch has wide application prospect in various industries such as mouse, automobile, airplane, control and detection. The micro-switch is used as a detection element, and certain functions are realized after the operation of the equipment triggers a button of the micro-switch on the detected equipment. However, the existing aviation plug micro switch is designed by adding a rubber dustproof cap on a contact. In the connection process of the plug and the socket, the rubber sheet at the top of the rubber dustproof cap is directly contacted with the copper insertion core of the socket, and the phenomenon of breakage can occur over time, so that the micro switch fails. In the event of such a fault, which would result in the aircraft ground power supply being in a self-protected state of shutdown, the interlock function may also fail for the associated equipment interlocked by the micro switch.
