Quiet snap action switch

A microswitch comprising:

• a switch casing in which a first common terminal member, and a second terminal member are fixed to a base portion, said second terminal member having a first fixed contact attached thereto;
• a hole formed in an upper cover of said switch casing;
• a push button which is vertically movably inserted into said hole;
• a movable member provided with a first movable contact, said movable member having a first end extending to a second end, said first end attached to said first common terminal member, said first movable contact adjacent said first end, wherein said movable member has a top side surface and a bottom side surface, wherein said bottom side surface comprises said first movable contact region;
• a fulcrum portion for serving as a fulcrum on which the movable member is leveraged through use of said push button;
• and
• a compression spring for biasing said movable member away from said first fixed contact;
• wherein said push button is configured for controlling the movement of the movable member and its attached movable contact, wherein depression of said push button brings said movable contact into contact with said first fixed contact, wherein release of said push button removes said movable contact from contact with said first fixed contact.

A microswitch comprising:

• a switch casing in which a first common terminal member, a second terminal member, and a third terminal member are fixed to a base portion;
• a hole formed in an upper cover of the switch casing;
• a push button which is vertically movably inserted into said hole;
• a movable member provided with a first movable contact region and a second movable contact region, said movable member having a first end extending to a second end, said first end defining a fixed end portion, said second end defining a free end portion, said ends defining there-between a central portion, said first end pivotally supported at the inner end portion of the first common terminal member at a base end portion thereof, said movable member having a top side surface and a bottom side surface, said first movable contact region adjacent said first end on said bottom side surface and facing a first fixed contact fixed to the inner end portion of the second terminal member, said second movable contact region adjacent said first end on said top side surface and facing a second fixed contact fixed to the inner end portion of the third terminal member;
• a fulcrum portion for serving as a fulcrum on which the movable member is leveraged through use of said push button, said fulcrum portion configured for contacting said bottom side at said central portion;
• and
• a compression spring, one end of which is pivotally engaged with a central portion of said movable member and said fulcrum portion;
• wherein said push button is configured for controlling the movement of the movable member and its attached movable contact regions, specifically when the push button is depressed, the first movable contact region is brought into contact with the first fixed contact and when the push button is released, the second movable contact region is brought back into contact with the first fixed contact.
