Abstract
A starter motor for an internal combustion engine has an electromagnetic switch (11) and a 'tooth against tooth' safety spring (37) to deform to allow the switch core (14) to move into a switch closing position even if the teeth on the starter pinion (10) and the starter ring gear of the engine are coincident rather than meshing as the pinion (10) contacts the starter ring gear. The 'tooth against tooth' spring is a leaf-spring (37) serving as a yieldable fulcrum for the yoke, and the moving core (14) of the switch accommodates slidably a contact-bearing rod (15) of the switch which rod also passes slidably through the fixed core (13) of the switch. At its end remote from the contact, the rod (15) engages a yieldable stop (34) which biases the rod towards a 'contact closing' position. The fixed core is thus devoid of a contact-closing spring and has a more massive flux path than it would otherwise do.
