Electrical pushbutton snap switch

An electrical snap switch comprising:

• a housing having a receiving portion;
• a pushbutton having a lower portion disposed in the housing and an upper portion extending out of the housing, wherein the pushbutton comprises an actuating portion laterally extending from the lower portion of the pushbutton, and wherein the pushbutton is configured to move vertically relative to the housing between a pushbutton upper active position and a pushbutton lower active position when an external force is applied to the pushbutton;
• at least a first pair of associated contact elements disposed in the receiving portion, the at least a first pair of associated contact elements comprising:
• a first fixed contact element disposed in the receiving portion, and
• a first movable contact element facing the first fixed contact element and configured to come into contact with the first fixed contact element for establishing a first conductive path between the first movable contact element and the first fixed contact element;
• and
• a snap-action switching device disposed in the receiving portion, the snap-action switching device comprising:
• a tilting driving member pivotally mounted at a pivotal end to the housing around an horizontal axis, the tilting driving member having a distal end distal to the pivotal end, and
• a traction spring extending longitudinally and having a first longitudinal end hooking to the distal end of the driving member, a second longitudinal end hooking to an interior side of the housing, and configured to pivot the driving member between an upper position and a lower position by the actuating portion of the pushbutton when the pushbuttons moves vertically relative to the housing;
• wherein the first movable contact element is a movable portion of a first elastically deformable conductive blade supported by the housing, and wherein the driving member comprises a first cam configured to cooperate with a cam follower portion of the first blade to deform or relax the first blade transversely to move the first movable contact element to come into contact or release from contact with the first fixed contact element.
