The utility model discloses an isolating switch with a moving contact position detection function, and aims to provide an isolating switch with a moving contact position detection function, which is good in reliability. The static contact comprises a static contact outer frame, a moving contact which is rotatably arranged in the static contact outer frame and is provided with two contact strips, two contact fingers which are symmetrically arranged on the static contact outer frame and are matched with the contact strips, a buffer pad which is arranged on the static contact outer frame and is in contact with the moving contact, a spring and an intelligent pressure sensor, the intelligent pressure sensor is installed on the static contact outer frame, and the measuring end of the intelligentpressure sensor corresponds to the action end of one contact finger and is close to the action end of the contact finger. One end of the spring is connected with the measuring end of the intelligentpressure sensor, and the other end of the spring is connected with the action end of the contact finger adjacent to the intelligent pressure sensor. The utility model can effectively satisfy the use of high-voltage direct-current power transmission engineering.
