Abstract:
A capacitance switch includes an electrode portion having a first electrode and a second electrode, a moving member, and a pressing member having a projecting portion. A distance between the moving member and the electrode portion is changed by displacing the projecting portion. The moving member has a first moving surface and a second moving surface. The projecting portion includes a first projecting portion and a second projecting portion. The first projecting portion is to be displaced by first pressing of the pressing member and brings the first moving surface close to the electrode portion. The second projecting portion is to be displaced by second pressing larger than the first pressing and brings the second moving surface close to the electrode portion.
