Abstract:
A push button type switch comprising:a body having a hollow interior portion which is divided into two operation spaces by a spacer having a through hole therein; a pressing element situated in a first of said operation spaces, said pressing element having protrusions extending from an operation section of the pressing element; a switching element situated in a second of said operation spaces; a plurality of conductive elements having first ends arranged to respectively engage the switching element and thereby establish an electrical connection between said conductive elements; and driving means including a depressing element positioned between said protrusions and connected to the operation section, said depressing element having an end passing through the through hole of the spacer; an elastic element surrounding the pressing element and having an end connected to the spacer; and a rotary seat pivotally installed on the body and having a guide groove for supporting the depressing element; one end of the rotary seat having a positioning portion connected to the switching element, wherein as a force is applied to the pressing element, the depressing element is pressed to compress the elastic element, wherein another end of the depressing element engages the guide groove so that the rotary seat shifts to drive the switching element to electrically connect the conductive elements, wherein by the restoring elastic force of the elastic element, the pressing element and the depressing element are restored to the original condition, and wherein the switching element has a contact piece having an end connected to the conductive elements; another end of the contact piece is connected to an elastic body firmly secured to the body, and a swingable piece is connected between the contact piece and the rotary seat.
