Switch structure, and chronograph mechanism and electronic timepiece using the same

A switch structure comprising:

• a terminal plate equipped with a plate-like main body portion and a plurality of elastic switch lever portions, each switch lever portion being equipped with an arm, portion which is connected to an outer peripheral edge portion of the plate-like main body portion at one side of a proximal end portion thereof and bent with respect to the outer peripheral edge portion of the plate-like main body portion at the one side of the proximal end portion thereof, which extends from the proximal end portion along an extension surface of the main body portion in a direction along the outer peripheral edge portion of the plate-like main body portion, and which is equipped with a pressing force receiving portion at a distal end thereof, and with an elastic contact portion further extending from the pressing force receiving portion of the arm portion;
• and
• an elastic switch lever supporting rigid support lever which is movably provided behind the pressing force receiving portion of each elastic switch lever portion in order to receive a pressing force behind the pressing force receiving portion of each switch lever portion and to guide displacement of the pressing force receiving portion when a pressing force is applied to the pressing force receiving portion of the arm portion of each elastic switch lever portion.
