MULTI-DIRECTIONAL INPUT SWITCH DEVICE, AND MOUSE WITH THE MULTI-DIRECTIONAL INPUT SWITCH DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a multi-directional input switch with simple structure and assured operation. SOLUTION: Four end part switches 100a to 100d and one center switch 100e are installed on a substrate 10, and the boss part 210 of an end part, switch pressing member 200 and four arms 220a to 220d are connected to each other through a semi-spherical member 230. A circular edge 422 in contact with the semi-spherical member is provided on the substrate side of a hole 421, which allows the stick part 320 of a center stick pressing member 300 to pass therethrough, formed in the upper surface member 420 of a holding member 400 so that the arms of the end part switch pressing member in neutral state slightly press the pressed surfaces 133 of the end part switch to receive the energizing force of a pressing spring 120. The contact part 310 of the center pressing member 300 is also formed so as to receive the energizing force of the spring of the center switch in neutral state.
