本考案は摺動式の接触機構を備え、プリント回
路基板上に実装して微小電圧電流回路に使用する
密閉型の超小型スイツチに関する。[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to a sealed ultra-compact switch equipped with a sliding contact mechanism, mounted on a printed circuit board, and used in a micro-voltage/current circuit.

O in the upper opening of the switch body where the operation part protrudes.
A ring (sealing member) was provided, and a board with a fixed terminal provided in the lower opening of the switch body was welded using an adhesive or an ultrasonic welder.

が不安定になるという欠点が存在した。C. Problems to be Solved by the Invention However, in the above-mentioned conventional switch, when the operating section is operated, the upper part of the movable element is always biased upward to drive the movable contact piece connected to the lower part of the operating section. This has the disadvantage that the O-ring disposed in the lower opening of the switch body is crushed, and as a result, the operating feel of the operating section becomes unstable.

の放置を必要とする等の欠点が存在した。 In addition, in the above-mentioned conventional switch, when joining the lower opening of the switch body and the board disposed there, the joint is sealed by using adhesive or welding with an ultrasonic welder. However, when using adhesive, it is difficult to apply the adhesive uniformly to the joint, causing problems such as sticking out and adhesion to other parts, and the viscosity of the adhesive , management of adjustment and formulation is complicated, and stability is difficult to maintain.Furthermore, after applying the adhesive, a heating process is required for complete adhesion, and it is necessary to leave the adhesive for a long time to achieve complete adhesion. There were drawbacks such as:

要となる欠点が存在した。 In addition, when using an ultrasonic welder, there are restrictions on material selection, such as the switch body and substrate to be joined being limited to thermoplastic resin, and the aim is to achieve both airtightness and joint strength, and maintain stability. In this case, there was a drawback that delicate adjustment and management of the welder was required.

イツチとしては不適当である。 In Japanese Utility Model Publication No. 44-23070, since the amount of change in the total pressure of the spring acting on the knob is applied to the waterproof ring, the friction and fatigue rate of the waterproof ring becomes faster, the waterproofing effect is lost, and the knob is Since it rotates in the entire circumferential direction, it is unsuitable for movable armature operation in which the movable armature swings within the same plane without changing its direction. Furthermore, Japanese Utility Model Publication No. 42-13712 discloses a device in which a slider pressed by a spring is advanced and retreated, and a movable contact piece is directly operated by the slider. It is impossible to open or close the terminals without direct action, and the switch is unsuitable for use as a sealed micro-miniature switch for a micro-voltage/current circuit where the height of the switch is limited.

We provide a sliding contact type sealed switch that has the advantage of avoiding various inconveniences when using ultrasonic welding, eliminating restrictions on the substrate material compared to welding with an ultrasonic welder, and simplifying welder adjustment and management. The purpose is to

る。 In addition, the present invention engages the convex part of the mover with the upper end of the concave part of the switch body, and operates the operating part from the center, right, and left without applying spring pressure directly to the sealing member. The upper opening of the switch body is sealed only by the elastic deformation of the sealing member itself, and the upper limit position of the mover is regulated by a recess in the switch body. By providing a concave groove that continues from the bottom to a predetermined height, the mover does not rotate by itself, and therefore the mutual movement between the mover piece fitted to the lower end of the mover and the fixed terminal of the board is on the same plane. The movable element, the push rod, and the spring are arranged at the front and rear parts of the movable element, respectively, so that even if the push rod is moved along the slope of the moderation plate, the spring pressure will not fluctuate at the convex part. The object of the present invention is to provide a switch in which fixed terminals are opened and closed smoothly and easily by a movable contact piece without affecting the sealing member in any way.

スイツチの構造。 A board 9 having a plurality of fixed terminals 10 is disposed in the lower opening 3 of the switch body 1.
A sealing member 6 is disposed in the upper opening 2 of the switch body 1, and the operating section 4 is disposed in contact with the sealing member 6 to protrude above the switch main body 1. In a closed type switch in which a movable element 5 is connected, which drives a movable contact piece 11 that slides on a fixed terminal 10 and is always urged upward, a required height is set at the center inside the switch body 1 from the lower end. Continuous recesses 8a and 8b are formed, and convex portions 7a and 7b formed at the upper end of the movable element 5 are engaged with these recesses 8a and 8b, respectively, so that the movable element 5 moves up and down within the same plane. A board 9 is attached to the lower front end of the mover 5.
A movable element piece 11 is disposed in contact with the fixed terminal 10 of the movable element 5, and is supported downwardly by a spring 14 at the rear lower end of the movable element 5, and moves along the inclined surface of a moderation plate 12 provided on the base plate 9. A push rod 13 is disposed, and the operation part 4 is reciprocated around the convex parts 7a and 7b, and the upward movement of the movable element 5 due to the elasticity of the spring 14 is caused between the upper ends of the concave parts 8a and 8b of the switch body 1 and the movable element. The structure of a sliding contact type sealed switch is characterized in that the switch is stopped at the engaging portions of the convex portions 7a and 7b of No.5.
