Abstract
Abstract A wireless multiple position switching system is disclosed for controlling the application of power to a load device from a plurality of remote locations. The switching system includes a power source, a load device, a master toggle switch and one or more slave toggle switches. A slave toggle switch generates an electromagnetic switching signal which changes the state of the master switch. The master switch is connected in series with the power source and the load device and controls the application of power to the load device in response to the switching signal from the slave switch or actuation of its own toggle.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
152 words
A two-position switch comprising: a ball bearing having an electrically conductive surface; a compression spring; a set of electrical contacts; and activation means including a toggle lever for activating said switch; said toggle lever having a first stable non-conductive resting position and a second stable non-conductive resting position, said activation means activated by moving said toggle lever from said first stable non-conductive resting position to said second stable non-conductive resting position, said activation means activated by moving said toggle lever from said second stable non-conductive resting position to said first stable non-conductive resting position; said toggle lever further including a compression spring aperture for accommodating said compression spring, said compression spring situated within said compression spring aperture and applying a force to said ball bearing such that said ball bearing momentarily rests across said set of contacts when said activation means is activated, to momentarily complete an electrical circuit across said contacts.
Claim 2
Dependent Claim
152 words
A two-position switch comprising: a ball bearing having an electrically conductive surface; a compression spring; a set of electrical contacts; and activation means including a toggle lever for activating said switch; said toggle lever having a first stable non-conductive resting position and a second stable non-conductive resting position, said activation means activated by moving said toggle lever from said first stable non-conductive resting position to said second stable non-conductive resting position, said activation means activated by moving said toggle lever from said second stable non-conductive resting position to said first stable non-conductive resting position; said toggle lever further including a compression spring aperture for accommodating said compression spring, said compression spring situated within said compression spring aperture and applying a force to said ball bearing such that said ball bearing momentarily rests across said set of contacts when said activation means is activated, to momentarily complete an electrical circuit across said contacts.
Claim 3
Dependent Claim
33 words
A two-position switch as set forth in claim 1 wherein said ball bearing, said compression spring, and said set of contacts are fabricated of metal, and all remaining components are fabricated from plastic.
Claim 4
Dependent Claim
38 words
A two-position switch as set forth in claim 1 further including current source means for applying a low-voltage direct current across said contacts, and current sensing means for sensing whether or not said contacts have been momentarily closed.
Claim 5
Dependent Claim
33 words
A two-position switch as set forth in claim 1 wherein said activation means requires the application of a force similar in magnitude to the force required to activate a standard household light switch.
Claim 6
Dependent Claim
46 words
A two-position switch as set forth in claim 2 wherein said movement of said toggle lever from said first position to said second stable resting position requires the application of a force similar in magnitude to the force required to activate a standard household light switch.
Claim 7
Dependent Claim
17 words
A two-position switch as set forth in claim 1 wherein said toggle lever is fabricated of plastic.
Claim 8
Dependent Claim
28 words
A two-position switch as set forth in claim 1 wherein the color of said toggle 1ever is selected from the group consisting of white, ivory, black and brown.
