Abstract
A magnetically operated switch wired in series between a source of electrical current and an electrical appliance. In one embodiment the switch is used in conjunction with a convenience wall outlet and is activated to supply power to the outlet by means of a cylindrical magnet carried by the mechanical ground pin of a conventional wall plug. Another embodiment utilizes a cylindrical magnetic in the form of a key for insertion into a receptacle for operating the magnetic switch. Another embodiment employs a magnetic switch and a magnetic type key for operating a relay having a switch capable of carrying large current loads.
Claims14
A safety switch comprising:
- an electrical power circuit, said power circuit having at least one electrical connection extending between a power source and said safety switch remotely positioned from said power source;
- a first magnetically activated switch means connected in series between said source and termination means;
- a magnet;
- and
- a magnet positioning means located adjacent to said first magnetically activated switch means for receiving said magnet therein whereby the magnetic influence of said magnet changes the state of said first magnetically operated switch means and opens said electrical power circuit.
A safety switch comprising an electrical power circuit having at least two electrical connections between a source and a remote location, said safety switch comprising:
- a normally open first magnetically operated switch means having an input and output;
- a magnet;
- a magnet positioning means located adjacent said first magnetically operated switch means;
- and
- a relay means having an activating coil with input and output connection and a normally open switch having input and output connections associated therewith, said first magnetically activated switch means is series connected between one of said at least two electrical connections and one of said coil connections, said normally open switch being in series with the other of said at least two electrical connections whereby when said magnet is inserted into said magnetic positioning means said first magnetically activated switch means is closed, current flows through said related coil causing said switch associated with said coil to close.
A safety switch comprising an electrical power circuit having two electrical connections between a source and a remote location said safety switch comprising:
- a normally open first magnetically operated switch means having an input and output;
- a magnet;
- a magnet positioning means for receiving said magnet located adjacent said first magnetically operated switch means;
- and
- a control means having an input, output and control connection, said input and output connections connected in series with one of said two electrical connections, said first magnetically activated switch means in series connected between one of said two electrical connections and said control connection whereby when said magnet is inserted into said magnetic positioning means said first magnetically activated switch means is closed and voltage is applied to said control connection causing current to flow through said control means.
