Abstract: A solenoid apparatus comprising a solenoid case (27) having an open end and a substantially closed end, a plunger (30) electromagnetically movably mounted in the solenoid case, and a substantially cup-shaped flexible water-tight boot (40). The cup-shaped boot (40) surrounds an end portion of the plunger (30) projecting from the solenoid case (27) and connected to the open end of the solenoid case, the flexible boot (40) having a bottom wall central portion intimately secured to the end portion of the plunger (30). The flexible boot (40) comprises a vent hole (44) defined by a hollow tube (45) extending through the boot wall in parallel to the plunger and a flexible valve plate (48) formed integral with and inside of the boot wall and biased by the elasticity of the material of the boot (40) into an open position (FIG. 5). The valve plate (48) is adapted to be pushed against the vent hole tube (45) by the plunger (30) to close the vent hole (44) when the plunger (30) is not operated, and the valve plate (48) is separated by its elasticity from the hollow tube (45) by the elasticity to allow air communication through the vent hole (44) when the plunger (30) is operated.

Abstract: A switch arrangement is disclosed which may be used with an enclosed fluid resistant container. A pin-like element is inserted through a wall of the container to actuate a switch contained within the container. Thereafter, the circuit is not easily deactivated. The switch arrangement includes a switch located within the container for activating a particular circuit function. The switch includes a mechanical trigger which is moved to effect the switch activation. A narrow switch actuator, such as a pin, is used for moving the trigger. A slide block is positioned between the trigger and a container wall for impacting the trigger in a single direction. A plug is placed in the wall and has an aperture therethrough for receiving the switch actuator, and the plug also includes a separate labyrinth path therethrough for passing fluid to the outside of the container. The aperture in the plug is structured such that the switch actuator fits slidably in the aperture and substantially seals the aperture. The switch actuator is moved through the aperture to force the slide block to impact the trigger, the switch actuator remains in the aperature to seal the plug, and the labyrinth path in the plug permits fluid to be released from the container.

Abstract: A small-sized relay and a method for fabricating the same are disclosed. The relay comprises a prefabricated relay mechanism and an insulating cover covering the relay mechanism. Prior to assembling the relay mechanism and cover, a laser machining device is utilized to form, in the cover, holes of very small diameter which permit flow of gas molecules therethrough but do not permit the flow of dust particles or liquid molecules therethrough. The prefabricated relay mechanism is covered with the cover formed with such holes, and the opening of the cover except the portion including the holes is closed to hermetically seal the relay mechanism.

Abstract: Disclosed a trigger switch including: a case having a switch chamber in which a switch mechanism is arranged in a sealed state; a plunger inserted slidably into a shaft hole formed on one end side of the case, coupled to the switch mechanism, and biased forward; and a trigger provided on a distal end of the plunger for operating the switch, wherein the switch mechanism includes an air pressure stabilizing mechanism configured to cancel an air compressing action in the interior of the switch chamber caused by the switch mechanism moving in the interior of the switch chamber. The air pressure stabilizing mechanism includes a communication hole extending from a rear end opening facing the switch chamber to a distal end opening on the plunger, and a plunger-engaging portion of the trigger includes a discharge port communicating with the communication hole and configured to release air from the communicating hole.
