Snap action switch for generating feedbacks

A snap action switch for generating a feedback when being pressed, comprising:

• a housing with a plurality of protruding blocks extending inwardly;
• a plunger disposed on the housing;
• a first elastic component coupled between the housing and the plunger for providing a first force against the plunger;
• a first electrical contact component and a second electrical contact component;
• a cam located within the housing and being movable by the plunger, wherein the first electrical contact component is disposed on the cam, and the second electrical contact component is coupled to the housing;
• a rotor disposed in the housing and associated with the cam;
• and
• a second elastic component coupled to the rotor for providing a second force against the rotor;
• wherein when the cam moves from an unpressed position to a partially pressed position, the rotor rotates such that a lower surface of the cam engages with an upper surface of the rotor, and when the cam moves from the partially pressed position to a fully pressed position, the rotor continues to rotate such that the upper surface of the rotor engages with a lower surface of at least one of the plurality of protruding blocks of the housing;
• and
• wherein the first electrical contact component is spaced from the second electrical contact component at all times when the cam is in the unpressed position, and the first electrical contact component contacts the second electrical contact component in at least one of the partially pressed position and the fully pressed position.
