PROBLEM TO BE SOLVED: To provide a contact switching device capable of preventing flow out of a conductive fluid from an injection port. SOLUTION: The contact switching device is provided with the body 1d which has a housing chamber 1d, in which a conductive fluid L is stored and a pair of contacts 5a, 6a are installed and an injection port 2f for injecting the conductive fluid L into the housing chamber 1d; and a closing plate 4 for closing the injection port 2f, and an actuator 7 which is a drive means to move the conductive fluid L stored in the housing chamber 1d and switching conduction state between the pair of contacts 5a, 6a. A check valve 9 is formed integrally on the inner wall of a first groove 2e of a first channel 1b to become a passage for injecting the conductive fluid L, in a hollow part 1a which constitutes a part of the housing part 1d and in which the conductive fluid L is stored.
