PROBLEM TO BE SOLVED: To provide a contact switching device capable of preventing adhesion of a surplus conductive fluid, in the surrounding of an injection port. SOLUTION: The contact switching device is provided with the body part 1 which has a housing chamber 1d in which a conductive fluid L is stored and a pair of contacts are installed and an injection groove part 20 which is connected to the housing chamber 1d on one-end side and has an injection port 2f for injecting the conductive fluid L into the housing chamber 1d on the other-end side; a closing plate 4 for closing the injection port 2f, and an actuator 7 which is a driving means for moving the conductive fluid L stored in the housing chamber 1d and switches the conduction state between the pair of contacts 5a, 6a. A depression part 9 depressed in thickness direction of the substrate 2 is formed so as to surround the surrounding of the injection port 2f and a prescribed spacing is provided between the injection port 2f and the depression part 9.
