Problems solved by technology
[0002] The micro switch is a common structure, which is mainly composed of a shell, a cover, a button, an incoming terminal and an outgoing terminal. When the button is pressed during use, the circuit is connected, otherwise the circuit is disconnected. Although it can meet The use requirements of general conditions, but the sealing of the connection between the micro switch housing and the cover of the traditional technology is not strong. There are also non-conductive) water mist will enter the switch cavity, resulting in the failure of this type of switch, and seriously burning key components, resulting in paralysis of the entire device

The sealed DC microswitch provided by the present invention relates to the field of switches, and includes a hollow switch housing and a switch body arranged in the switch housing; the switch body includes a push rod for controlling the switch body; The switch housing is provided with a lever hole; the lever extends out of the lever hole; a sealing ring is sleeved and fixed on the lever hole; the sealing ring seals the lever and the lever hole gap. The sealed DC micro switch provided by the present invention has good sealing performance and mute effect, can effectively prevent particles, water mist, etc. from entering the micro switch, damage the switch, and prolong the service life of the switch.
Description
technical field [0001] The invention relates to a switch, in particular to a sealed DC micro switch. Background technique [0002] The micro switch is a common structure, which is mainly composed of a shell, a cover, a button, an incoming terminal and an outgoing terminal. When the button is pressed during use, the circuit is connected, otherwise the circuit is disconnected. Although it can meet The use requirements of general conditions, but the sealing of the connection between the micro switch housing and the cover of the traditional technology is not strong. There are also non-conductive) water mist will enter the switch cavity, resulting in the failure of this type of switch, and seriously burning key components, resulting in paralysis of the entire device. Contents of the invention [0003] Therefore, in order to solve the above technical problems, the present invention provides a sealed DC micro switch, which has better sealing performance and can effectively preve...
