方向(上方向)へのストローク規制を行う。 A through hole 33 is formed in the case 31 on which the receiver R r is placed, and the switch knob 2 is inserted into the through hole 33 . The switch knob 2 is integrally molded using a synthetic resin with a low friction coefficient, such as polyacetal resin (static friction coefficient: 0.32). The shape of the switch knob 2 is, for example, oval in side view (FIG. 1) and rectangular in plan view (FIG. 5), and at least one end (inner end) of the lower surface 2d is formed into a convex curved surface. Make point or line contact with the plate surface. A stopper portion 10 projecting like a brim is provided at a predetermined position on the outer surface of the switch knob 2 to regulate the outward (upward) stroke.

Screw 1 into the inner surface of the upper case 31, overlapping one end.
Fasten with screws 5a and 15b. The tip of the leaf spring 3 is a free end, and its plate surface is brought into contact with one end 2d of the switch knob 2 to urge the switch knob 2 outward in a natural state. Base plate 1
1 has rigidity, and the other end is bent to form a stopper part 12 located below the leaf spring 3. In addition,
This stopper portion 12 has a function of preventing the switch knob 2 from coming off inward when the switch knob 2 is pushed in by a finger or the like more than necessary.

行に離間し、開位置となる。 Further, the side portion of the base plate 11 is bent at a substantially right angle to the leaf spring 3 to form a contact mounting portion 13 for installing the switch contact pieces 4a and 5a. The switch contact pieces 4a and 5a are entirely formed into an elastic strip shape, and have the switch contacts 4 and 5 at their tips.
are provided, and the rear end portions are provided with connection terminals 4b and 5b for connecting lead wires. The intermediate portions of the switch contacts 4a and 5a are fixed with an insulating resin body 14, and this resin body 14 is screwed to the contact mounting portion 13. Further, 15 indicates an insulating boss provided on the switch contact piece 4a. In addition, an operating plate portion 3a is provided at a portion where the switch contacts 4 and 5 are located by extending a portion of the leaf spring 3 and contacting the insulating boss 15. In the natural state, the switch contact pieces 4a and 5a are spaced apart from each other and are substantially parallel to each other, and are in the open position.

利点がある。 With this configuration, the hook switch device 1 can be attached by simply screwing the screws 15a and 15b at two locations (ordinarily only at one location), making the assembly work extremely easy. Further, since the base plate 11 is integrally provided with the stopper part 12 and the contact mounting part 13, there are advantages that the number of parts is reduced and the structure is simplified, and furthermore, it can be made smaller and more compact.
次に、フツクスイツチ装置1の機能について説
明する。 Next, the functions of the switch device 1 will be explained.
まず、第3図のように本体30のフツク32に

作板部3aの変位となるため、スイツチ接点4は
同部3aから離れ、自然状態に復帰する。よつ
て、フツクスイツチ装置1は開位置となる。 First, when the handset R is attached to the hook 32 of the main body 30 as shown in FIG. 3, the switch knob 2 is pushed inward into the upper case 31 by the handset part R r , resulting in the state shown in FIG. 1. . At this time, leaf spring 3
bends against its own elastic force. Since this displacement results in a displacement of the operating plate portion 3a, the switch contact 4 separates from the portion 3a and returns to its natural state. The switch device 1 is therefore in the open position.
他方、フツク32から送受話器Rを外した場合
にはスイツチノブ2が自由となるため、板バネ3

位によりスイツチ接点4は接点5の方向へ押さ
れ、フツクスイツチ装置1は閉位置となる。 On the other hand, when the handset R is removed from the hook 32, the switch knob 2 becomes free, so the leaf spring 3
Due to the elastic return of the switch knob 2, the stopper portion 10 of the switch knob 2 is pushed outward until it comes into contact with the through hole 33, as shown in FIG. Therefore, the switch contact 4 is pushed in the direction of the contact 5 due to the displacement of the leaf spring 3, and the hook switch device 1 is placed in the closed position.

接触面である一端2dの摩擦係数は低く、また凸
曲面に形成するため、円滑にスライドする。 By the way, in this case, since the leaf spring 3 is supported in a cantilevered manner, the locus on the tip side draws an arc. Therefore, the lower surface 2d of the switch knob 2 will slide slightly on the plate surface of the leaf spring 3, but since the friction coefficient of the one end 2d, which is the contact surface of the switch knob 2, is low and it is formed into a convex curved surface, it will slide smoothly. Slide.

きる。 Although the embodiments have been described in detail above, the present invention is not limited to these embodiments.
For example, a switch contact is a concept that includes not only a direct electrical contact as in the embodiment, but also a switch knob in another independent switch (for example, a micro switch, etc.). Further, the transmitter/receiver is a concept that includes any communication device such as a transceiver, a telephone, etc., and the handset/receiver may be of a type that is individually equipped with a transmitter or a receiver. Other details such as configuration, shape, arrangement, quantity, material, etc. may be arbitrarily changed without departing from the gist of the present invention.
