た。In general, the contact opening/closing structure of a relay is such that a movable contact 2 provided at the tip of a contact spring 1 is connected to a fixed contact 3 as shown in Fig. 1.
The slider 6 is operated by a rotating piece 5 which is operated by the solenoid 4, as shown in FIG. A sliding clip type is generally used, in which a clip-shaped movable contact piece 7 is supported, and fixed terminals 8, 8, etc. arranged in a straight line are held and slid by the movable contact piece 7. Met.

ばならない等の問題があった。However, as the opposed contact type mentioned above repeatedly opens and closes at the same point on the contact surface, insulating material forms and adheres to the contact surface, which causes poor contact. With the dynamic clip type, the sliding resistance between the clip and the terminal is large, which forces the slider return spring to be large, and the slider must be moved against the large return spring and sliding resistance. Therefore, there were problems such as having to use a solenoid with a large suction force.

るスイッチに存する。The present invention solves these problems and eliminates the formation and adhesion of insulators on the contact parts, requires only a small return spring, and has low sliding resistance, allowing stable opening and closing operations even with small solenoids. The purpose of the present invention is to provide a switch that can be obtained, and its gist is to support a movable contact piece on an actuator slidably housed in a switch case, to pass the movable contact piece through the switch case, In a switch that is inserted between a pair of opposing fixed terminals so that they can be freely connected and separated,
The actuator supports the top of a movable contact piece formed by bending an elastic plate material into a substantially U shape, and integrally includes a bulging contact portion at the tip of both pieces of the movable contact piece, the bulging contact portion. An expanding curved portion is formed on one end side of the fixed terminal in the switch case where the terminal contacts and separates, and when the switch is turned on, the bulging contact portion of the movable contact piece is formed from the expanding side of the expanding curved portion of the fixed terminal. The switch is characterized in that it is brought into contact with the proximal end side of the expanding curved portion.

a, a chevron-shaped bulging contact portion 12b at the tip of 12a;
, 12b, and a contact piece support protrusion 13.14 integrally formed on one end side of the bottom surface of the operating element 11.
The top portion 12C of the movable contact piece 12 is clamped and fixed between the two pieces 12a, 12a in a movable state.

またその可動接触片１２の両端部外側に対応させて突起
１５．１５が一体成形され、可動接触片１２の先端１２

d and the outside of 12d are in contact.

一方スイッチケース１０の底部基板１６には各可動接触
片１２．１２に対応させてそれぞれ一対の固定端子１７
．１７が突設されている。On the other hand, a pair of fixed terminals 17 are provided on the bottom board 16 of the switch case 10, corresponding to each movable contact piece 12, 12.
．． 17 is provided protrudingly.

この各一対の固定端子１７．１７は可動接触片１２の両

れるようにしている。Each pair of fixed terminals 17, 17 are located on both sides of the both pieces 12a, 12a of the movable contact piece 12, and are fixed in opposing positions with a gap between them so that they do not come into contact with the both pieces 12a, 12a of the movable contact piece 12. Moreover, the distance between both bulging contact parts 1 is
2b, 12b, and when the movable contact piece 12 is moved together with the operating element 11, both the bulging contact parts 12b, 12b are press-fitted between the two fixed terminals 17, 17.

またこの両固定端子１７．１７は可動接触片１２の膨出

る。In addition, these fixed terminals 17.17 are integrally molded with expanded curved parts 17a, 17a, in which one ends of the bulging contact parts 12b, 12b side of the movable contact piece 12 are separated from each other, and when the movable contact piece 12 is turned on, The bulging contact portions 12 b , 12 b come into contact with the tip sides of both the expanded/curved portions 17 a , 17 a , and are further moved to form the bulged contact portions 12 b , 12 .
While b is compressed and narrowed, both expansion curved portions 17a, 17
It is press-fitted to the vicinity of the proximal end of a and then stopped.

即ちこのスイッチは第６図に示すようにＯＮ動作時には
固定端子１７．１７のａ点にまず膨出接触部１２ｂ、１
２ｂが接触して摺動し、ＯＮ動作の停止時にはｂ点で接
触状態が維持される。That is, as shown in FIG. 6, when this switch is turned ON, the bulging contact portions 12b, 1 are first connected to the point a of the fixed terminal 17.17.
2b contacts and slides, and the contact state is maintained at point b when the ON operation is stopped.

る。When the ON operating force is released, the return spring 18 urges the expansion curved portion 17a toward the return side.
The force acting on the movable contact piece 12 in the expanding direction acts on the movable contact piece 12 in the direction of returning the movable contact piece 12, and the OFF operation is performed.

またこのときｂ点からａ点まで摺動し、ＯＦＦ動作時の
スパークはａ点で発生する。Also, at this time, it slides from point b to point a, and a spark occurs at point a during the OFF operation.

。In the above-described embodiment, the solenoid 19 is used as shown in FIG.
In this example, a movable piece 20 operated by a movable piece 20 is inserted into the casing 10 to push the actuator 11, but in other cases, one end of the actuator protrudes from the casing and is linked to a solenoid or other driving means. It's also good.

してもよいものである。The movable contact piece 12 is attached to the actuator 11 by forming a protrusion 21 on the actuator 11 and inserting the top 12C into a U-shaped groove formed on the protrusion 21, as shown in FIG. It's also good.

更に、可動接触片１２に対する固定端子１７の配置は第
７図に示すように可動接触片１２の先端側に配置しても
よいものである。Furthermore, the fixed terminal 17 may be arranged on the tip side of the movable contact piece 12 as shown in FIG. 7.

本考案のスイッチは上述のように構成され、ＯＦＦ状態

にリレーに使用した場合にソレノイドの吸引力が小さく
てよく、小型化、低廉化が遠戚されるものである。The switch of the present invention is constructed as described above, and when in the OFF state, there is no sliding resistance between the movable contact piece and the terminal, and as the ON operation stops, the contact pressure increases to obtain a predetermined contact pressure. Moreover, since the elasticity of the movable contact piece acts on the return side, the return spring can be small, and therefore, especially when used in relays, the suction force of the solenoid can be small, making it a distant relative of miniaturization and low cost. It is.

また、ＯＮ動作停止時の接触点とＯＦＦ動作時における
アーク発生点とが別々であり、しかも接触はスライドし

る。In addition, the contact point when the ON operation is stopped and the arc generation point during the OFF operation are separate, and the contact is made by sliding, so even if an insulating material is generated by the arc due to the cleaning action, the contact point when the ON operation is stopped is different. It has various effects such as less contact failure and high electrical stability even with minute currents, and its effectiveness is enormous.
