Abstract: A position detection device detects a current positon of a operation member among positions including a predetermined position and includes a detection system that includes a part to be detected and 3N magnetic sensors S. The operation member can move to the positions in N (≥3) different directions from the predetermined position. Movement of the operation member between the predetermined position and another position cause outputs from three of the magnetic sensors to be switched. The magnetic sensors of which outputs are switched by a movement of the operation member between the predetermined position and a first position are all different from the magnetic sensors of which outputs are switched by a movement of the operation member between the predetermined position and a second position.
