Abstract
This is an electrical switching method and apparatus wherein a magnetic reed switch is activated by means of a disc magnet moving into and out of the magnetic field of the magnetic reed switch. The motion of the disc magnet is caused by gravity, a change in the orientation of a device supporting the disc magnet, a flow of fluid against the disc magnet, an impact affecting the disc magnet, vibration, fluid level changes, or other forces causing the disc magnet to roll or otherwise change its position with respect to the magnetic reed switch. Variations include means by which paraplegics and other invalids can signal for assistance or communicate by blowing breath against disc magnets and where a bank of disc magnet devices can control a diversity of devices such as bed controls, televisions, telephones, etc.
Claims16
A method for electrical switching comprising:
- placing a magnetic reed switch having at least two electrical contacts adjacent support means for a disc magnet in such manner that a portion of the support means will be within and a portion of the support means will be without the magnetic field of the reed switch;
- placing a disc magnet on the support means at a location without the magnetic field of the magnetic reed switch;
- and causing the disc magnet to move to a position within the magnetic field of the magnetic reed switch thus activating the magnetic reed switch.
An electrical switching device comprising:
- a magnetic reed switch;
- magnetic reed switch holding means;
- a disc magnet supported by disc magnet support means;
- and means to move the disc magnet into and out of the magnetic field of the reed switch.
A method for a disabled person to communicate which includes:
- causing a disc magnet upon a disc magnet support surface to roll from a position exterior the magnetic field of a magnetic reed switch associated with the disc magnet support surface to a position interior said magnetic field.
An electrical switching apparatus comprising:
- a magnetic reed switch;
- magnetic reed switch holding means;
- a disc magnet supported by disc magnet support means;
- a magnetic disc magnetic restraining means normally restraining the magnetic disc from entering the magnetic field of the magnetic reed switch;
- and means to overcome the magnetic restraining means so as to allow movement of the disc magnet into and out of the magnetic field of the reed switch.
Apparatus for disabled, handicapped, invalid, and other persons and the like to control a variety of devices comprising:
- a plurality of magnetic disc/magnetic reed switch wireless transmitter devices each of which is on a specific wireless frequency different from each of the others and each of which is accessible to, and capable of being activated by a person;
- a plurality of wireless receiver devices each of which is on a specific wireless frequency which matches the frequency of one of the transmitter devices and is connected to a device which may be activated by receipt of a signal by the receiver device from the frequency matching transmitter device.
