Abstract
Abstract Briefly, according to the invention, a tilt switch 30 comprises a body 20 including a substantially conical cavity. The substantially conical cavity has at least a portion 24 which is electrically conductive. The tilt switch further has an electrical contact 32 spaced from the conductive portion 24 of the cavity. Finally, a conductive ball 34 located within the cavity selectively interconnects the electrical contact 32 and the conductive portion 24 of the cavity when the tilt switch 30 is tilted. In another aspect of the invention, a jitter switch 40 comprises a body 50 including a substantially concave shaped cavity. The substantially concave cavity has a curved bottom surface having a conductive portion (48) thereon and a sidewall having a separate conductive portion (44) thereon. A conductive ball 46 within the cavity intermittently interconnects the conductive portion of the bottom surface 48 with the conductive portion on the sidewall 44 when the jitter switch 40 is in motion.
