形成されている。[Prior Art] Conventionally, a seal type tact switch generally includes a base 1 made of an electrically insulating material and a cover 3 fixed to the base 1, as shown in FIGS. 6 and 7. have. On the upper surface of the base 1 (the left side surface in FIG. 1), a circular concave portion 5 and the concave portion 5 with respect to the outside of the concave portion 5 are formed.
An annular flat portion 7 that is parallel to the bottom surface of the above and serves as a regulating portion for regulating the movable contact 17 described later is formed. An annular convex portion 9 is formed on the upper surface of the flat portion 7. Further, a pair of guide walls 11 is formed outside the flat portion 7.

る。On the bottom surface of the recess 5 of the base 1, a central fixed contact 13 is provided in the central portion and a pair of peripheral fixed contacts 15 are provided on the sides. A dome-shaped movable contact 17 facing the central fixed contact 13 is housed inside the recess 5. The movable contact 17 has a central portion facing the central fixed contact 13 and a peripheral portion mounted on the peripheral fixed contact 15. A sealing rubber 19 is provided on the upper surface of the base 1. An annular spacer 21 is provided on the sealing rubber 19.

される。Inside the annular spacer 21, a pusher 23 that presses and drives the movable contact 17 via the rubber 19 for sealing is provided. Since the cover 3 is fixed to the base 1,
The spacer 21 and the pusher 23 are retained and retained.
Further, the spacer 21 is pressed by the cover 3, so that the peripheral portion of the sealing rubber 19 is embedded in the annular convex portion 9. As a result, the contact portion inside the recess 5 is sealed and protected.

らの間を平坦部７で結んでいる。Peripheral fixed contact 15 is arranged such that its contact surface is on the circumference of inner diameter D defining recess 5 so as to ensure contact with the peripheral portion of movable contact 17. Further, in order to prevent the resin from flowing out to the contact surface at the time of molding the base 1, the peripheral fixed contact 15 on the inner surface of the recess 5 is prevented.
The inner surface of the part where is located is the inner surface of the other part (inner diameter D surface)
Has been extended slightly outward than. Therefore, the annular convex portion 9 is provided on the circumference that circumscribes the inner surface of the portion where the peripheral fixed contact 15 is located. Although there is a slight distance between the annular convex portion 9 and the inner surface of the concave portion 5, the flat portion 7 connects them between the base 1 and them.

すい。[Problems to be Solved by the Invention] However, in the seal type tact switch shown in FIGS. 6 and 7, the flat portion 7 is arranged closer to the center of the switch than the annular convex portion 9, and therefore the assembly is performed by the assembling machine. While moving in the station, the movable contact 17
As shown in the figure, it is easy to ride on the flat portion 7 of the base 1.
この状態でシールタイプタクトスイッチを組立てると、
スイッチのクリック感が悪くなってしまうという問題が
ある。When the seal type tact switch is assembled in this state,
There is a problem that the click feeling of the switch becomes bad.
それ故に本考案の課題は、組立時の可動接点の平坦部へ
の乗り上げを防止したシールタイプタクトスイッチを提
供することにある。Therefore, an object of the present invention is to provide a seal-type tact switch that prevents the movable contact from riding on a flat portion during assembly.

Movable contact of
An annular convex portion formed around the concave portion, and between the annular convex portion and the concave portion for restricting the movable contact, along the annular convex portion in a portion other than the vicinity of the peripheral fixed contact. A seal type tact including a regulating portion formed by means of the above, a sealing rubber that faces the annular convex portion, a spacer that presses the sealing rubber against the annular convex portion, and a carver that fixes each portion to the base. In the switch, a seal-type tact switch is obtained in which the restriction portion is formed as an inclined surface that is inclined with respect to the bottom surface of the recess.

平坦部７が形成されていない。This seal type tact switch has an annular convex portion 9 outside the surface defined by the inner diameter D of the base 1 made slightly larger than the outer diameter of the movable contact 17 (hereinafter referred to as “inner diameter D surface”). ing. The annular projection 9 has two types of cross-sectional shapes shown in FIGS. 3 and 4. FIG. 3 shows a cross section in the range indicated by θ in FIG. Is formed as an inclined surface 27. Further, FIG. 4 shows a cross section of the remaining portion. That is, the inclined surface 27 is between the annular convex portion 9 and the concave portion 5,
It is formed along the annular convex portion 9 in a portion other than the vicinity of the peripheral fixed contact 15. Here, between the annular convex portion 9 and the inner diameter D surface of the concave portion 5, the flat portion 7 parallel to the bottom surface of the concave portion 5 is not formed.

み、良好なシール性が得られる。After the movable contact 17 is mounted on the base 1, the annular sealing rubber 19, the spacer 21, and the pusher 23 are mounted. Then, the metallic cover 3 is fixed to the base 1. The cover 3 can be fixed in a conventional manner. As a result, the convex portion 9 of the base 1 bites into the sealing rubber 19 and good sealing performance is obtained.

になる。Further, since there is no flat portion between the convex portion 9 and the inner diameter D surface of the concave portion 5 of the base 1, the movable contact 17 does not ride on such a flat surface. Therefore, even if the movable contact point 17 bounces or moves due to vibration or the like during the switch assembly, the inclined surface 27 ensures that the movable contact point 17 is settled in the recess 5.

できる。[Effects of the Invention] As described above with reference to the embodiments, according to the seal type tact switch of the present invention, the convex portion for sealing is formed in an annular shape, and the portion between the convex portion and the concave portion is an inclined surface. Therefore, even if the movable contact moves during the switch assembly, the inclined surface ensures that the recess is settled. For this reason, the movable contact does not run on the upper surface of the base during assembly, so that it is possible to prevent a switching failure or a touch failure due to that.
