Claim:
1. A switch device, comprising: a one-piece housing wall defining a first opening into a first cavity portion, and defining a necked-down entrance from said first cavity portion to a second cavity portion, which is farther away from said first opening than said first cavity portion; a tripping magnet sized to pass through said first opening and through said necked-down entrance, said tripping magnet being received in said second cavity portion; a switch sized to pass through said first opening and to abut said necked-down entrance, said switch being received in said first cavity portion and being electrically connected to at least one connection terminal projecting out of said first cavity portion through said first opening; said switch including an actuator button biased by a biasing spring, said actuator button moving axially, along an actuator button axis, from a deactuated position to an actuated position; wherein said second cavity portion is shaped to receive said tripping magnet with a close enough fit to serve as a guide track that restricts movement of said tripping magnet to linear movement along said actuator button axis, from an “at rest”, deactuated position, to a depressed position in which the tripping magnet depresses the actuator button against the biasing spring to actuate the switch; wherein there is a space between said first opening and said switch, and wherein a potting material fills said space to seal said switch and said tripping magnet inside said one-piece housing.
