Abstract
A relay has an elongated rocking armature which is mounted on a coil assembly having a centrally located fulcrum about which the armature seesaws. The coil assembly nests in, and is supported by an insulating mounting block. A cover fits over the entire assembly and extends far enough beyond the bottom of the mounting block to form a retaining wall for receiving a sealant which may be poured therein and which thereafter solidifes. The sealant flows through holes in the mounting block and locks the coil assembly in place by integrally joining the block and coil assembly. Arms are formed on the four corners of the armature assembly, immediately over cantilever electrical contact springs. As the armature rocks, the arms affect the vibrations of the cantilever spring. That is, when the springs flex in a direction away from the arms, the effective vibrating length is the entire length of the springs. When it flexes toward the arms, the effective vibrating length is in the order of a half of the entire spring length.
