| 1. A switch unit, comprising:
a switching control element that is provided so as to be operated to rock, and includes a stepped portion;
a movable contact that moves in response to a rocking operation of the switching control element and includes an abutting
portion to be brought into contact with the stepped portion;
a stationary contact to and from which the movable contact is connected and disconnected in response to the rocking operation,
wherein the movable contact includes a contact piece portion whose distal end portion is slidable over an insulator and the
stationary contact; and
an intermediate portion between the distal end portion and a base portion of the contact piece portion is brought into contact
with the switching control element,
wherein when the switching control element is operated to rock, the abutting portion elastically rides on the stepped portion
to give a click to the rocking operation.
