Responsive mouse click mechanism
A responsive mouse click mechanism includes a body ( 100 ), a key ( 200 ), and an elastic member ( 300 ). A switch ( 110 ) is arranged in the body ( 100 ). The key ( 200 ) includes an extension arm ( 210 ), one end of the extension arm ( 210 ) is pivotally connected to the body ( 100 ), and the other end of the extension arm ( 210 ) is in contact with the switch ( 110 ). The elastic member ( 300 ) is connected between the body ( 100 ) and the extension arm ( 210 ). The elastic member ( 300 ) pushes the extension arm ( 210 ) and a moment is thereby loaded on the extension arm ( 210 ) to preload pressure on the switch ( 110 ) without triggering the switch ( 110 ).
