ABSTRACT:
In a solenoid switch according to the invention, a magnetic plate is disposed on one side of a solenoid coil in an axial direction of the solenoid coil. A contact cover is arranged with the magnetic plate interposed between the contact cover and the solenoid coil in the axial direction. First and second fixed contacts are received in the contact cover and respectively electrically connected to first and second terminals that are to be electrically connected to an electric circuit. A resistor is electrically connected between the first and second terminals to limit current flowing through the electric circuit when the first and second fixed contacts are electrically disconnected by a movable contact. The resistor is received in the contact cover and interposed between the magnetic plate and the first and second fixed contacts in the axial direction.
