Abstract
A thin push switch used in a portable electronic apparatus includes a less number of components jointed together without any adhesive controlled hardly, and can thus be favored with mass production. The push switch includes an insulating spacer having first cramp-locked tabs cramp-locked with the first terminals of a fixed plate and second cramp-locked tabs cramp-locked with the second terminals of a contact plate. The fixed plate includes a fixed contact, and the contact plate includes a movable contact. Accordingly, the contact plate, the insulating spacer, and the fixed plate can be joined together without an adhesive.
