A latch type solenoid switch including a frame, a permanent magnet providing magnetic force to the frame, a coil unit which offsets the magnetic force of a permanent magnet when power is supplied, and a moving part which adheres to and detaches from the frame depending on the power supply to the coil unit. Anti-corrosion coating is applied to the surface of the frame and the moving part. The plating thickness on the contact surfaces between the frame and the moving part is thinner than on the other surfaces of the two bodies.
