Abstract:
1. A magnetically-sensitive switch comprising: a housing comprising a top wall, a bottom wall, two opposite sidewalls extending from the bottom wall and a pair of sliding grooves defined in the sidewalls, the housing defining a side opening between the sidewalls; a metal block placed on the bottom wall of the housing; a sliding block with opposite ends slidably engaged in the sliding grooves; a rigid link pivotally interconnected between the metal block and the sliding block; a first plate attached to the housing to cover the side opening; and an electrical switch fixed to the first plate and arranged at the side opening; wherein, when the metal block is attracted by a magnetic force generated by a magnet which is placed adjacent to the top wall, the metal block is movable from the bottom wall of the housing to a raised position adjacent to the top wall, thereby the upward movement of the metal block driving the rigid link to drive the sliding block to slide toward the side opening along the sliding grooves until the sliding block triggers the electrical switch to generate a switching signal.
