Abstract
An improved electromagnetic relay having a wafer of material with positive temperature coefficient of resistivity (PTC) mounted inside the relay combines a sturdy construction with low manufacturing costs adapting the relay for use as a starting relay for electric motors of compressors. For this purpose, the magnetic members of the relay are incorporated in the electrical relay circuit and are provided with attachments for plug-on connections of the relay to circuit pins of motor-compressor units.
