A personal security communication system is disclosed. It is comprised of a motion and position sensor adapted to detect motion and lack of motion. The sensor has a motion and position sensing switch having means indicative of the motion of a contact making element in the switch and is adapted to provide at least a first and second electrical state according to the motion and lack of motion of the contact making element. Means is provided for detecting the first and second electrical state. The detecting means being adapted to provide a signal indicative of the electrical state of said switch. The system also includes user input means, processor means for receiving information from said motion sensing means and said user input means and adapted to format a digital data message indicative of said information, a transmitter means for transmitting said message, an alarm means activatable by said processor means and a power supply means for powering said processor means, transmitter and alarm means.

A motion and position sensing switch comprising: an enclosure having a cavity; a contact-making element resting in said cavity; a plate having a conductive circuit thereon that caps said cavity; said cavity having a conductive region near said plate, said plate and said conductive circuit being electrically isolated from said conductive region, wherein, when said enclosure pivots to a predetermined position about a horizontal axis, said contact-making element resting in said cavity moves to make contact between said conductive region and said conductive circuit; and, said conductive circuit comprising first and second conductive areas separated by a nonconductive region such that when said contact-making element makes contact between said first conductive area and said conductive region of said cavity, said switch is in a first state and when said contact-making element makes contact between said second conductive area and said conductive region of said cavity, said switch is in a second state.
