ABSTRACT:
A switch operated by a reciprocating pin mounted to the base of an electromagnetic reciprocator, which is a motor with a coil that retrieves electricity stored in the electromagnetic field of a permanent magnet. The switch consists of a reciprocating plastic block with two adjacent parallel grooves which engage the reciprocating pin. The pin strikes a curve at the end of each groove and causes the block to reciprocate in a direction perpendicular to the direction of reciprocation of the pin. Two terminal arms mounted on the block alternately contact two pairs of terminal posts connected to the coils of electromagnets in the electromagnetic reciprocator, reversing the circuit through the coils and the polarity of the electromagnets and causing the electromagnets to alternately attract and repel the permanent magnet. The switch operates the electromagnetic reciprocator, and the electromagnetic reciprocator operates the switch.
