In this construction there are provided: a case; several contact members exposed within the case; several lead terminals electrically connected to some of the contact members, and a support member, all insert molded in the case and protruding outwards; and a circuit breaker provided outside the case, one of its ends supported by a lead terminal and its other end supported by the support member. Thereby compact and efficient unitary construction are attained, and space within a device to which this construction is to be fitted, can be economized. The contact members may be five in number, and may be arranged within the case for contact in a linear relationship, alternatingly serving as input side and output side contact members, with the end ones and the middle one serving for being switched between while the other two serve as common contact members. In this case, the two end contact members should be electrically connecetd together, and the construction may further include a pair of contact members which slidingly move, in synchronization, over the common contact members and their neighboring contacts. Alternatively, the construction may further include a movable contact member mounted slidably over the contact members with one of its surfaces confronting a surface of a slidable impeller member, one of these surfaces being formed with a hemispherical protuberance and the other being formed with a hemispherical depression cooperating therewith, thus coupling together these members.
