A power feeding control device is provided with a main body accommodating an electric circuit for controlling power supply to a motor vehicle from a power source. First and second cables to be connected to the motor vehicle and the power source extend from the longitudinally opposite ends of the main body, respectively. The second cable includes a plug having a plug body accommodating a second contact electrically connected to a first contact provided in the main body, and a retaining ring attached to the plug body such that the retaining ring is rotatable about an axial direction of the plug body while being restricted to move in the axial direction. By screwing the retaining ring onto a thread portion of the main body, the retaining body is detachably attached to the main body in the state that the second contact is electrically connected to the first contact.

An electrical rotary switch in use with an automatic transmission for detecting the operative position of the transmission and controlling an electric circuit associated with the positions of the transmission. The switch comprises a switch casing composed of a base plate and a cover plate each formed of an electrically insulating material and provided in its interior surface with a plurality of fixed contacts. Supported between the base plate and the cover plate is an actuator which is rotatable about a rotation axis in response to the changing positions of the automatic transmission. The actuator has a coupling end to be interlocked with a control output shaft of the transmission which is provided to rotate in synchronism with changing positions of the transmission. The actuator has first and second opposed faces each confronting the interior surface of each one of the base plate and the cover plate, and carries first and second movable contacts respectively on the first and second faces for electrical conduction between selective ones of the fixed contacts on the individual plates depending upon a particular angular position of the actuator about the rotation axis. Also formed on the switch casing is a terminal assembly comprising a plurality of terminal pins leading from the individual fixed contacts for connection with the external electric circuits. The movable contacts are carried in slots in the actuator. A third moveable contact is used to energize the starter circuit when the park and neutral positions of the transmission are detected.

摘要:
A molded article is formed by an injection molding method of embedding a workpiece within a resin by the use of a mold. The mold has a mold cavity, at least one supporting pin removably projecting into the mold cavity to support the workpiece in the mold cavity, and at least one gate for injecting the resin into the mold cavity. The supporting pin is forced against the workpiece to support the workpiece within the molded cavity. The resin is injected into the molded cavity through the gate. In the present method, the supporting pin is removed from the mold cavity after the workpiece is supported by pressure of the resin injected in the mold cavity. The injection of the resin is continued to fill a hole left in the mold cavity by removal of the supporting pin. After the injection is finished, the injected resin is hardened to obtain the molded article. This method is useful for integrally molding a conductive member with an electrically insulating resin to form a component of an electrical device, for example, a base plate or cover plate of an electrical rotary switch for detecting positions of an automatic transmission of an automobile.
