20110140813 | ELECTROMAGNETIC SWITCH WITH ENHANCED STABILITY IN OPERATION - A normally-closed electromagnetic relay which may be used in controlling a supply of electric current to an automotive engine starter. The electromagnetic relay is equipped with a resistor and a shirt circuit. The short circuit is created by closing of relay contacts when a relay coil is energized to establish an electric connection between ends of the resistor to supply the current from a battery to an electric motor without flowing through the resistor and opened by opening of the relay contacts when the relay coil is deenergized to supply the electric current from the battery to the electric motor through the resistor. If a motor drive signal line leading to the electromagnetic relay is disconnected when the relay coil is kept energized, it will cause the short circuit to be established to ensure the supply of current to the motor, which also avoids the melting down of the resistor. | 06-16-2011 |
