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 drive means for moving the conductive fluid L stored in the housing chamber 1d and switches the conduction status between the pair of contacts 5a, 6a. A projected wall part 21, which protrudes inside and has a projection face 21a substantially in parallel to the injection port 2f opposed to it is formed with a prescribed spacing from the injection port 2f in the thickness direction of the body part 1, on the inner wall of the injection groove part 20.
