Abstract
The utility model relates to the technical field of switches, and particularly relates to a pressure switch applied to a vehicle steering pump. The pressure switch comprises a shell which is provided with an installation through hole, a top rod whose one end is inserted into one end of the installation through hole and position-limited in the installation through hole and the other end is outside the shell, and a contact rod whose one end is inserted into the other end of the installation through hole and the other end is outside the shell. The contact rod is provided with a contact head. The installation through hole is internally provided with a metal film sheet which is arranged between the top rod and the contact head of the contact rod. The metal film sheet is pushed to contact the contact head by the top rod. The installation through hole is internally provided with a film sheet conductive seat which is position-limited in the installation through hole and contacts the metal film sheet. The contact rod penetrates through the film sheet conductive seat. An insulating ring is arranged between the film sheet conductive seat and the contact rod. The pressure switch is reasonable in structural design and convenient to install and connect. Installation is completed only by inserting the top rod into the installation position of the steering pump so that production and manufacturing are facilitated.
