To obtain a simple slidable switch structure of click operation type for changing over conductive patterns on a printed circuit board fixed in a card housing of a card module, the switch comprises three fixed through hole contacts formed in the board, and a movable contact formed with two convex contact portions. The movable contact is preferably coated with an insulating material except for the two convex portions and is directly disposed within the housing. When the movable contact is moved to and fro, the movable contact member deformably assembled within the insulation member is selectively and slidably brought into contact with two of the three fixed through hole contacts for changing-over operation.
