AI Technical Summary
Technical Problem
The existing normally open reverse pressure switch is prone to stagnation or contacts with different centers during use, which affects the normal operation of the gearbox.
Method used
A normally open reverse pressure switch is designed, using a contact piece to move up and down within the plug assembly through the rail, combining the limit position of the sealing ring and the buffer groove to reduce the possibility of stagnation and contact between different centers.
Benefits of technology
Through the orbital movement of the contact piece and the limit design of the sealing ring, the problems of stagnation and different center contact are effectively reduced, and the reliability and stability of the pressure switch are improved.

Abstract
A normally open reverse gear pressure switch, a push rod is installed in the inner cavity, the push rod is divided into a push rod body, a push rod lower end and a push rod upper end, the push rod lower end is a first reduction portion passing through the plug cover, the push rod upper end is a second reduction portion, a contact piece covers the push rod and the middle through hole passes through the push rod upper end, a contact point is provided at the contact piece corresponding to the pin, a contact piece spring is provided between the upper end of the contact piece and the upper wall of the inner cavity, and a sealing ring is provided in the housing between the push rod assembly and the push rod lower end. Its advantages are: the limit of the sealing ring and the compression amount are controllable; the sealing ring has a buffer groove to reduce the excessive assembly force caused by rubber interference; the contact piece moves up and down in the plug assembly through the track to reduce the problems of stagnation and eccentric contact.
