摘要：An electromagnetic switching device for controlling the flow of electrical current between a plurality of pins. The switching device includes a base, an input pin, first and second output pins, a reed, an actuator, a magnetic field generator, and generator pins. The reed and actuators are movable between a first position which electrically couples the first output pin and the input pin, and a second position which electrically couples the second output pin and the input pin. Dielectric compatible plastic material with enhanced shielding characteristics is located in apertures in the base to structurally retain the pins therein. The actuator further includes a center body portion, an arm integrally molded with the center body portion extending generally laterally outward therefrom, and a finger depending downwardly from the arm. The finger is structurally coupled to the movable reed to move the reed between its first and second positions. The magnetic field generator includes a hollow centrally-located sleeve and a coil wound around the sleeve. The tip member of the actuator is positioned within the hollow sleeve for movement along a longitudinal center axis. The magnetic field generator further includes mechanical connectors attached to a respective end of the coil to frictionally receive a respective generator pin and electrically connect the pins with their respective end of the coil. Application of current to the coil creates a magnetic field forcing the tip member in a predetermined direction, which moves the actuator, with its tip member, from one of its first and second positions to the other of its first and second positions. A mounting adapter positioned at the lower side of the base permits easy conversion of a pin-through switch to a surface-mount switch.
