Abstract
A vacuum activated switch for use in or with a drinking container and straw. The switch includes a flexible membrane, a traveling contact which rests on the flexible membrane, and a fixed contact which is mounted on an integrated circuit board. Suction upon the straw creates a partial vacuum, causing the membrane to deflect, thereby carrying with it the traveling contact. This motion will cause the traveling contact to come into electrical contact with the fixed contact, thereby completing a circuit. The integrated circuit board is programmed to initiate an action upon completion of the circuit, such as, preferably, the production of a preselected melody or other sound.
