Abstract
A switch for closing a circuit comprising a first electrically conductive switch arm, the first switch arm comprising a first electrical connector; a second electrically conductive switch arm, the second switch arm comprising a second electrical connector and a receiving receptacle, the receiving receptacle comprising an electrically conductive side wall which extends around a displacement axis to define a receiving volume, the edge of the side wall proximate to the first switch arm defining a receiving mouth; at least one electrically conductive arcing rod adapted to be displaced along the displacement axis towards and away from the receiving mouth; at least one receiving receptacle magnet arranged to provide a magnetic field which extends along the displacement, axis within a portion of the receiving volume; the first switch arm being adapted to be displaced towards the second switch arm to switch the switch from an open configuration in which the first and second electrical connectors ere spaced apart from each other and a closed configuration In which the first and second electrical connectors are in electrical contact with each other; the first switch arm being arranged such that as it is displaced towards the second switch arm to switch the switch from the open configuration to the dosed configuration it abuts the arcing rod, urging the arcing rod along the displacement axis towards the receiving mouth.
Claims (19)
1. A switch for closing a circuit comprising a first electrically conductive switch arm, the first switch arm comprising a first electrical connector; a second electrically conductive switch arm, the second switch arm comprising a second electrical connector and a receiving receptacle, the receiving receptacle comprising an electrically conductive side wall which extends around a displacement axis to define a receiving volume, the edge of the side wall proximate to the first switch arm defining a receiving mouth; at least one electrically conductive arcing rod adapted to be displaced along the displacement axis towards and away from the receiving mouth; at least one receiving receptacle magnet arranged to provide a magnetic field which extends along the displacement axis within a portion of the receiving volume; the first switch arm being adapted to be displaced towards the second switch arm to switch the switch from an open configuration in which the first and second electrical connectors are spaced apart from each other and a closed configuration in which the first and second electrical connectors are in electrical contact with each other; the first switch arm being arranged such that as it is displaced towards the second switch arm to switch the switch from the open configuration to the closed configuration it abuts the arcing rod, urging the arcing rod along the displacement axis towards the receiving mouth.
2. A switch for dosing a circuit as claimed in claim 1, wherein as the arcing rod is displaced towards the receiving mouth the distance between the arcing rod and receiving mouth is reduced to less than a predetermined arcing distance before the distance between the first and second electrical connectors is reduced to less than the predetermined arcing distance.
3. A switch for closing a circuit as claimed in either of claims 1 or 2, further comprising a biasing mechanism adapted to bias the arcing rod in a direction away from the receiving mouth along the displacement axis.
4. A switch for closing a circuit as claimed in claim 3, wherein the biasing mechanism is a spring.
5. A switch for closing a circuit as claimed in any one of claims 1 to 4, wherein at least one receiving receptacle magnet is a permanent magnet.
6. A switch for closing a circuit as claimed in any one of claims 1 to 4, wherein at least one receiving receptacle magnet is an electromagnet.
7. A switch for closing a circuit as claimed in claim 6 wherein the electromagnet comprises at least one coil wrapped around the outside of the side wall.
8. A switch for closing a circuit as claimed in any one of claims 1 to 7, wherein the second switch arm is connected to a capacitive or inductive load.
9. A switch for closing a circuit as claimed in any one of daims 1 to 8 further comprising a displacement mechanism for displacing the first switch arm relative to the second switch arm to switch the switch between open and closed configurations.
10. A switch for closing a circuit as claimed in daim 9, wherein the displacement mechanism is adapted to pivot the first switch arm about a pivot to switch the switch from an open configuration to a closed configuration.
11. A switch for closing a circuit as claimed in claim 9, wherein the displacement mechanism is adapted to displace the first switch aim linearly to switch the switch from the open configuration to the closed configuration.
12. A switch for closing a circuit as claimed in any one of claims 1 to 11, wherein the arcing rod comprises an electrically conductive bulge at its tip.
13. A switch for closing a circuit as claimed in claim 12, wherein the bulge is spherical.
14, A switch for dosing a circuit as claimed in either of claims 12 or 13, further comprising a magnet at least partially arranged In the bulge, the magnet being arranged to provide a magnetic field which extends along the displacement axis.
15. A switch for dosing a circuit as claimed in any one of claims 12 to 14, further comprising an electrically insulating cap on the bulge, the cap extending away from the arcing rod.
16. A switch for closing a circuit as claimed in claim 15, when dependent on claim 14, wherein the magnet extends beyond the bulge into the cap.
17. A switch for dosing a circuit as claimed in either of claims 12 or 13, further comprising a ferromagnetic material at least partially arranged within the bulge.
18. A switch for dosing a circuit as claimed in any one of daims 1 to 17, wherein the side wall is circular in a plane normal to the displacement axis.
19. A switch for closing a circuit as claimed in any one of claims 1 to 18, further comprising a voltage source connected to the first switch arm.
