To provide a switch unit suitable for realizing functional control of a plurality of kinds, especially realizing a space saving.

The switch unit 1 is constituted such that (1) if a moving member 13 is moved to an end point in the X1 direction from a reference position by pressing a knob 23 in the X1 direction and stopped as it is, a switch 5 is set on once by being pressed with one projection 19 of the moving member 13, and such that (2) if the knob 23 is pushed to the final point in the X1 direction, immediately released, and the moving member 13 is returned to the reference position, the switch 5 is set on twice within the specified time Ts. The switch unit 1 is constituted such that (3) if the operation similar to (1) is conducted in the X2 direction, the switch 5 is pressed with three projections 21 of the moving member 13 and set on three times, and (4) if operation similar to (2) is conducted in the X2 direction, when the moving member 13 is returned to the reference position by the force of a spring 17, the switch 5 is set on three times, and total six times within the specified time Ts. Thereby, each operation can be discriminated by the frequency of on.
