Abstract
An electromagnetic switch for a starter includes a coil that includes a first lead wire connected to a power supply side and a second lead wire connected to a ground side, the coil being supplied with an energization current through the first and second lead wires to form an electromagnet while a starter relay is on. The electromagnetic switch further includes a surge suppression device that absorbs part of energy emitted from the coil when the starter relay is turned from on to off so that a remaining part of the energy is applied to the starter relay to cause an arc current to flow between contacts of the starter relay.
