A variable flux starter and switch system (222, 222-1) including a starter motor (234) with motor field winding first and second portions (74a, 74b), a control unit (150, 150-1) capable of selectively issuing starter activation and desired flux level signals (68, 70), a motor energizing switch (76) moveable between open and closed positions consequent to issuance of the starter activation signal (68), and a regulating device (84, 84-1 ) that transitions between default and activated operational states consequent to issuance of the flux level signal (70), The regulating device (84, 84-1) has a moveable blocking member (94b) and relatively moveable contact members (86, 88), and in one of the default and activated operational states, electrical contact between the contact members (86, 88) is permitted or prevented by the blocking member (94b). Current through the closed motor energizing switch (76) substantially bypasses a motor field winding portion (74b) when electrical contact between the contact members (86, 88) is permitted, and is conducted through both portions (74a, 74b) when prevented. Also, a method for varying starter motor flux levels.
