Abstract
Abstract An electrical power system for a house or the like, where there is a master switch by which outlets throughout the house may be turned off, without interfering with the subsequent activation of the outlets through individual local switch assemblies for the various outlets. Operation of the master switch causes a momentary interruption of current in the electrical distribution lines in the house. Each of the outlets or groups of outlets is provided with a respective switch assembly comprising a relay switch that is held in a closed position by activation of a holding circuit, which in turn is supplied with power through the relay switch. Thus the momentary interruption of current by the master switch causes momentary deactivation of the holding circuits of the switch assemblies of these various outlets to cause them to move to their off position and thus de-energize these outlets throughout the house. The various outlets can be later individually turned on and off by means of an on-off switch means in the individual switch assemblies.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
303 words
In an electrical power system for a house or the like, where there are a plurality of power outlets at various locations, a system which provides for individual operation of said outlets at their related locations for both activation and deactivation of related outlets, and also for deactivation of said outlets from a master location without interference with subsequent individual activation and deactivation of said outlets, said system comprising: a. a plurality of switch assemblies, each of which is operatively connected to at least a related one of said outlets for individual operation thereof, each switch assembly comprising: 1. a first normally open switch connected to its related outlet and having a closed position where it delivers power to said outlet and an open position where power is not delivered to said outlet, 2. holding circuit means to hold said first switch in its closed position to transmit power to its related outlet, 3. said holding circuit means being connected to said first switch to be energized by said first switch in its closed position, in a manner that closure of said first switch causes activation of said holding circuit to maintain said first switch in its closed position, and 4. other on-off means proximate the location of its related outlet and operatively connected to said first switch to move said first switch between its open and closed positions, b. master switch means having an operating position to momentarily interrupt power to said switch assemblies whereby when said master switch means is moved to its operating position, each switch assembly has its holding circuit deactivated to cause its related first switch to return to its normally open position, whereupon operation of master switch causes deactivation of all of said switch assemblies, which remain deactivated until subsequent activation, as by its related on-off means.

In an electrical power system for a house or the like, where there are a plurality of power outlets at various locations, a system which provides for individual operation of said outlets at their related locations for both activation and deactivation of related outlets, and also for deactivation of said outlets from a master location without interference with subsequent individual activation and deactivation of said outlets, said system comprising: a. a plurality of switch assemblies, each of which is operatively connected to at least a related one of said outlets for individual operation thereof, each switch assembly comprising: 1. a first normally open switch connected to its related outlet and having a closed position where it delivers power to said outlet and an open position where power is not delivered to said outlet, 2. holding circuit means to hold said first switch in its closed position to transmit power to its related outlet, 3. said holding circuit means being connected to said first switch to be energized by said first switch in its closed position, in a manner that closure of said first switch causes activation of said holding circuit to maintain said first switch in its closed position, and 4. other on-off means proximate the location of its related outlet and operatively connected to said first switch to move said first switch between its open and closed positions, b. master switch means having an operating position to momentarily interrupt power to said switch assemblies whereby when said master switch means is moved to its operating position, each switch assembly has its holding circuit deactivated to cause its related first switch to return to its normally open position, whereupon operation of master switch causes deactivation of all of said switch assemblies, which remain deactivated until subsequent activation, as by its related on-off means.
Claim 3
Dependent Claim
19 words
holding circuit means to hold said first switch in its closed position to transmit power to its related outlet,
Claim 4
Dependent Claim
19 words
holding circuit means to hold said first switch in its closed position to transmit power to its related outlet,
Claim 5
Dependent Claim
45 words
The system as recited in claim 1, wherein said master switch means comprises relay means having a normally closed relay switch, and a master control switch having an operative position to momentarily activate said relay means to move the relay switch to its open position.
Claim 6
Dependent Claim
44 words
The system as recited in claim 1, wherein said on-off means comprises an on switch connected in parallel with said first switch means, whereby closure of said on switch causes activation of said holding circuit to move said first switch to its closed position.
Claim 7
Dependent Claim
46 words
said holding circuit means being connected to said first switch to be energized by said first switch in its closed position, in a manner that closure of said first switch causes activation of said holding circuit to maintain said first switch in its closed position, and
Claim 8
Dependent Claim
