HYDRAULIC SWITCH MODULE

PROBLEM TO BE SOLVED: To provide a hydraulic switch module that can suppress a position shift between members, and reduces physical constitution in a plate thickness direction and decrease the number of components.SOLUTION: A hydraulic switch module 11 includes a first electrode 111, a second electrode 112 capable of electrically contacting the first electrode 111, a first hole portion 113 formed in the first electrode 111, and a second hole portion 114 formed in the second electrode 112. A housing 12 has a housing hole portion 121 housing the hydraulic switch 11. A connection circuit 13 is provided to the housing 11, and has one end capable of being connected electrically to the first hole portion 113 and the other end capable of being electrically connected to an electronic control device. A plate member 14 is fixed to the housing 12, and has a projection part 15 to support the hydraulic switch 11. The projection portion 15 is hit and crushed while being inserted into the second hole portion 114 to electrically connect to the second electrode 112.
