Abstract
A button switch connected to a cap and includes a base having a pillar, a flexible acoustic member having fixing and flexible rods, a sleeve, an upward-force-applying member abutting against the sleeve and the base, a resilient arm, and a cover disposed on the base. The sleeve rotatably jackets the pillar, passes through the cover to be connected to the cap, and has first and second convex portions, first and second concave portions, and a protruding edge located between the second convex portion and the second concave portion. The resilient arm selectively abuts against a first or second position on the first convex portion. When the resilient arm abuts against the first position and the protruding edge is located above the flexible rod, the flexible rod crosses the protruding edge and then collides with the cover to make a sound when the sleeve receives an external force to move downward.
