Abstract: A switch includes a housing, a switching mechanism housed in the housing and configured to switch a state of connection between at least two terminals exposed out of the housing by using a common contact and two switching contacts, and an electronic component that is disposed in the housing and electrically connects the terminals to each other. The switching mechanism includes a first metal plate that is connected to a first contact, which is one of the common contact and the two switching contacts, and includes a first exposed part to which a first electrode of the electronic component is soldered by laser irradiation, and a second metal plate that is connected to a second contact, which is another one of the common contact and the two switching contacts, and includes a second exposed part to which a second electrode of the electronic component is soldered by laser irradiation.

Abstract: First guide supports and second guide supports are integrally formed on an external base material to which external terminals are fixed. Guide protrusions and guide concave parts, which extend vertically, are formed on the housing of a switch device. When each guide protrusion and its corresponding guide concave part are guided by a first guide support and a second guide support during the attachment of the switch device to the external base material, the switch device can be easily attached.

Abstract: A spring piece is formed integrally as part of a drive arm that presses an operational body. The spring piece is disposed between a pressing part at which the drive arm presses the operational body and a linkage part that acts a swinging fulcrum. A contact part between the spring piece and a case is positioned closer to the linkage part than the bend bottom end is. When the drive arm swings from an initial orientation to a completely swung orientation, the spring piece can generate an elastic return force. The elastic return force does not largely increase even when the drive arm swings.

Abstract: A switch device includes a casing that includes a recessed bearing portion, a rotatable drive member that includes a shaft portion disposed in the bearing portion, a switch driven by the drive member, and a covering member that includes a pressing structure provided so as to press an upper portion of the shaft portion and that is secured to the casing. The covering member includes an operating portion that faces the drive member such that the operating portion is able to press the drive member and that is formed of an elastically deformable elastic material and a base portion that is secured to the casing, that is formed of a synthetic resin material, and that is integrated with the operating portion. The pressing structure is integrated with the base portion and formed of an elastically deformable elastic material.

Abstract: A switch device includes a housing having a case and a holding member, a moving member, a biasing member, a movable contact, a common fixed contact, a first switching fixed contact, a second switching fixed contact, extending portions, at least two terminal members, and resistors for obtaining the resistance value between two terminal members, and fixing portions to which the resistors are soldered. The holding member includes a bottom wall portion that covers the bottom of the case, and a holding wall portion holding the fixing portions. The holding wall portion is formed of a first synthetic resin material having heat resistance, and the bottom wall portion is made of a second synthetic resin material having a heat distortion temperature lower than that of the first synthetic resin material. A method for manufacturing a switch device includes a first molding step, a resistor mounting step, and a second molding step.
