In a magnet switch for a starter, a first contact portion and a second contact portion are connected in parallel between a battery and a motor. The first contact portion makes contact through a resistive component so that the motor starts rotation at low speed. By this, a pinion is pushed in an axial direction by an axial component of splines and brought into mesh with a ring gear in a condition that its rotation is restricted. Thereafter, the second contact portion makes contact in accordance with further movement of a plunger so that electric power is fully supplied to the motor through the second contact portion, thereby starting engine. A fixed contact of the first contact portion is made of a carbon material. The resistive component is provided by the carbon material.
