This invention relates to a surge protection device (10). More specifically, the invention relates to a surge protection device for protecting electronic equipment against damage from high voltage spikes induced in power, television/satellite and/or telecommunication lines arising mainly from localised lightning strikes. The surge protection device Includes a housing (12) with a plurality of input and output sockets(14, 16) for connecting to inputs (i.e. power, TV antenna, etc.) and outputs (i.e. electronic equipment): respectively. The device further includes a switch (18) for electrically connecting and disconnecting the input sockets (14) from the output sockets (16), the switch (18) comprising stationary contacts (20) and movable contacts (22) located on a movable switch arm (18A), the movable arm (18A) being movable between a connected state wherein the stationary (20) and movable contacts(22) are in electrical connection with one another, and a disconnected state, wherein the stationary (20) and movable contacts (22) are displaced from one another to form an air gap there between. The device (10) further includes a motor (26) for moving the movable switch arm (18A), a controller for actuating operation of the motor (26) and a detector for detecting; an event thereby to trigger operation of the controller. |
