ABSTRACT:
An electrical relay construction in which the function of the actuating magnetic field of operating the relay is separated completely from the function of providing contact closure force. A pair of electrically conductive, spherical bodies (18, 19) are rollably clamped by spring means (28) between a common, electrically conductive plate (20) and individual platforms (14, 15, 16) connected to the relay terminals (11, 12, 13). The common plate (20) is mounted on an actuating member (21) controlled by a solenoid (31) to roll the bodies (18, 19) between the common plate (20) and the terminal platforms (14, 15, 16) to complete the possible relay conducting paths.
