ELECTROMAGNETIC SWITCH PROVIDED WITH CURRENT DETECTOR AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To provide a simple electromagnetic switch provided with a current detector which is hard to be magnetically saturated. SOLUTION: This switch is provided with an electromagnetic switch 20 having a fixed contact 22 and a ring-like current detector 200 threaded with the fixed contact 22 and having a hole 202e for detecting a magnetic field generated by a current flowing through the fixed contact 22. The current detector 200 is provided with a ring-like winding core part 202 formed of a non- magnetic material, and a coil 206 which has a winding start part 206s and a winding end part 206e throughout which a wire 204 is wound around the winding core part 202 and wherein the winding start part 206s and the winding end part 206e are located adjacently to each other.
