ABSTRACT:
An elastomeric compression element for an electromagnetic exciter unit which has a generally semi-circular outer periphery, an elongate inner periphery, end portions merging the inner and outer peripheries, a planar base surface and a contoured contact surface. The central portion of the element is dimensioned to have a height and thickness greater than that at the end portions for providing a non-linear spring action with the reciprocating free mass inside the unit during electromagnetic conduction.
