Abstract: An electromagnetic relay of a simple structure for reliably making and breaking a high load voltage. First and second fixed contact terminals are mounted on an insulating base block. First and second branched moving pieces are attached to the lower side of a hanging portion of a spring member. When a relay coil is not excited, the first and second moving pieces are resiliently urged into contact with a back-stop plate, displaced from the first and second fixed contact elements. When the relay coil is excited, contact elements attached to the first and second moving pieces are resiliently urged into contact with respective contact elements attached to the first and second fixed contact elements, electrically connecting the respective first and second fixed contact terminals.

Abstract: An electromagnetic relay of a simple structure for reliably making and breaking a high load voltage is provided.

Abstract: A reed relay comprising a reed switch having a pair of leads and a magnetic coil assembly for driving the reed switch, the magnetic coil assembly being composed of a magnetic coil wound around a cylindrical bobbin having an insulating flange at each end of the cylindrical bobbin, a terminal insulator integrally continuous with each flange, and a plurality of terminal leads insulated from one another by each of the terminal insulators. One embodiment of the present invention is a cylindrical bobbin having an electric conductivity so as to act as an electrostatic shield for the reed switch inserted thereinto, and another embodiment of the present invention is a method for fabricating the magnetic coil assembly comprising a step of forming a cylindrical bobbin and the terminal leads in each side of the cylindrical bobbin by using a patterned sheet of metal, wherein the cylindrical bobbin is continuous with the ground terminal lead in each side.

Abstract: A reed relay includes a reed switch with contacts, and a pair of terminals connected to the contacts. A tubular electrostatic shield defines an axially extending central bore within which the reed relay is inserted. A coil assembly has a winding drum, and a coil provided on the winding drum. The winding drum defines an axially extending central bore within which the electrostatic shield is inserted with the reed switch. A first pair of leads extend oppositely to each other, and are connected to the electrostatic shield at the opposite ends of the coil assembly. A second pair of leads extend oppositely to each other, and are connected to the electrostatic shield at the opposite ends of the coil assembly. A third pair of leads extend oppositely to each other, and are connected to the coil at the opposite ends of the coil assembly. A fourth pair of leads extend oppositely to each other, and are connected to the terminal of the reed switch at the opposite ends of the coil assembly.
