Description of the invention (〖2) Next, after placing the insulator 13 on the upper end portion of the cylindrical wall 3 of the first case 2, the waterproof member 14 is superposed on the insulator 13 in order. Next, the second lever 20 is accommodated in the accommodating portion 17 of the second housing 15 and the button portion 21 is protruded from the hole portion 19 a of the top plate portion 19 of the second housing 15, and is used in this state. The crotch portion 18 abuts on the waterproof member 14 so that the second casing 15 is placed on the upper end portion of the cylindrical wall 3 of the first casing 2. Then "the roller (roller) and other appropriate means slowly press the ring-shaped protrusion 3a inward (direction of arrow A in Fig. 2) to produce plastic deformation", and the ring-shaped protrusion 3a and the circle The upper end portion of the cylinder wall 3 holds the crotch portion 18 of the second casing 15 to support the second casing 15 to the first casing 2. The assembly of the switch 1 can be completed by assembling as described above, and after assembly, it will become a protruding (out) strip (groove) 1 8 a formed under the crotch 18 and will be trapped in the waterproof member 14 and sealed. 1 The housing 4 in the housing 2 'the small diameter portion of the first rod 1 2 1 2 a upper end face and the pressing portion, 1 2 c' will abut the bottom of the insulator 1 3 and the top of the movable contact 1 1 at the same time, The second rod 20 abuts the upper surface of the second portion 2 2 against the lower plate portion 19 of the second housing 15 and is prevented from falling upward. As for the pressing portion 2 3, the waterproof member 14 and the insulator 1 are used. 3 and it is in a state of being opposed to the center portion of the small-diameter portion 12 a of the first rod 12. With the thus-assembled switch 1 ', the terminals 9b, 10b are connected to a circuit of a circuit board (not shown) to be mounted on a washing machine or the like, and various operations are set and controlled. That is, when the button part 21 of the second lever 20 is pressed, the second lever 20 will slide inside the accommodating part 17 of the second housing 15 and the pressing part 23 will make the waterproof member 14 and the insulator. 1 3 _This paper & degree applies to China Solid State Standards (CNS) A4 specification ⑵0x297 public love)-] 5- ~ (Please read the precautions on the back before filling this page) —Order ---- line Δ7 ^ 346 Ο 9, _Β7 ______ 5. Description of the invention (13) Bend to press the small-diameter part 1 of the first rod 1 2 a »With the pressing, make the first rod 12 2 The pressing portion 1 2 c presses and bends the movable contact 11, so that the movable contact 11 is turned upside down and contacts the pair of fixed contacts 9, 10 and 9c, 10c, so that the pair of contacts can be turned on. The contacts are fixed between 9 and 10 and the switch is turned on. Therefore, various actions can be set and controlled. In this state, when the button part 21 of the second lever 20 is pressed (released), the waterproof member 14 and the insulator 13 can be restored to their original states by their respective elastic restoring forces. The second rod 20 and the pressing portion 2 3 are pushed up together to return to the original state, and at the same time, the bending of the movable contact 1 1 is released with the rise of the second rod 20 and the movable contact 1 is released. The revertive restoring force of 1 will push up on the first rod 12 and the movable contact 11 will be separated from the pair of fixed contacts 9 and 10 and the contact 9c and 10c will form a pair of fixed contacts 9 and 10. The state where the switch is disconnected. In this way, the 'assembled switch 1 is installed on a washing machine or the like and is placed at the water', even if a drop of water is dripped, because the insulating wall 7 and 8 are used to make the base 9 a of the fixed contact 9 exposed. The output part is separated from the terminal part 10b of the other fixed contact 10, and between the terminal part 9b of one fixed contact 9 and the exposed part of the base 10 of the other fixed contact 10. "Therefore, there is no connection between the two by water droplets, so that a pair of fixed contacts 9 and 10 can be maintained in a non-conducting (on) state", and a pair can be reliably prevented.

Description of the invention (14) It is also the first due to customer requirements, etc. Even if the size and shape of the casing 2 is changed, there is no need to change the base 9a, 1 of a pair of fixed contacts 9 and 10 to be buried. The size of the protruding portion 6 of 0 a (the width H of the protruding portion 6 in FIG. 3) can often be kept constant, so that it can be unified—for the fixed contact 9 ′ 10 between the terminal portions 9b ′ l〇b The dimensions allow standardization of the dimensions between the terminal portions 9b, 10b. [Effects of the Invention] The present invention is implemented in the form described above, and can exhibit the effects described below. The structure is as follows: a pair of fixed contacts formed by conductive wires, and a shell supporting the pair of fixed contacts close to each other, and arranged to be exposed in pairs from the outer wall surface of the bottom of the case toward the outside of the case. The exposed portion is located between the pair of fixed contacts, and between the exposed portion of the one fixed contact and the exposed portion of the other fixed contact, the entire opposing surface of the bottom outer wall surface of the pair of fixed contacts is arranged. Surface insulation wall, so * the insulation wall can be used to separate the exposed part of the fixed contact on the one side and the exposed part of the other fixed contact on the other side, so that there is no connection between them by water droplets, which can often Since the non-connected state between the pair of fixed contacts is maintained, a short circuit can be reliably prevented from occurring between the pair of fixed contacts. Because of the structure, a protruding portion integrated with the outer wall surface is arranged on the bottom portion, the pair of fixed contacts has a base portion and a terminal portion that is bent by being connected to the base portion, and the terminal portions are made to protrude by the protrusion. The two parts are buried in the opposite position and the aforementioned base is buried in the aforementioned protruding part so that a pair of <Please read the matter of interest on the back before filling in this page) Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs.

Description of the invention (is) Fixed contacts are supported outside A shell, and the base portion of the pair of fixed contacts is exposed from the side of the protruding portion along the bottom outer wall surface to configure the exposed portion, and the terminal portions of the pair of fixed contacts are arranged along the aforementioned The side of the protruding part is exposed, and it is on the outer wall surface of the bottom and between the exposed part of the base part of the one fixed contact point and the terminal part of the other fixed contact point, so as to cover the pair of fixed contact points. An insulating wall is arranged on the entire facing surface, so that a portion of the base portion can be exposed from the protruding portion to the outside of the case to support the pair of fixed contacts without burying all of the base portion in the case. Therefore, it is possible to reduce the cost of the shell material which exposes a portion of the aforementioned base portion. In addition, the size and shape of the aforementioned shell have changed due to customer requirements, etc., and the size of the protruding portion for burying the base of the pair of fixed contacts can be kept constant. Therefore, the aforementioned pair of fixed contacts can be unified The dimensions between the terminal portions make it possible to standardize the dimensions between the aforementioned terminal portions. The insulating wall is formed to have a larger diameter than at least one of the pair of fixed contacts, so that the exposed portion of the base portion that is attached to the one fixed contact can be separated and cut from the other one with certainty. Between the terminal portions of the fixed contact, or between the terminal portion of the one fixed contact and the exposed portion of the base portion of the other fixed contact. Furthermore, since the end surface of the insulating wall that is far from one side of the protruding portion is tapered, water droplets do not accumulate on the end surface of the insulating wall that is far from the protruding portion, so that the cutting wall can be reliably separated Water droplets attached to the end surface.
