Overview – MAGNETIC SWITCH 146457 Series
If you run Cummins starting positions as the magnetic switch engaging the starter solenoid, the Cummins MAGNETIC SWITCH 146457 and its series variants give you flexible sourcing without compromising fit.
Parts Characteristics
A magnetic switch that energises and engages the starter circuit, so the engine cranks when the key calls and releases when it should. It carries the pull-in and hold that the starter depends on, so a true, correctly rated switch keeps the cranking clean.
Applicable Models & Applications
Used at Cummins starting positions specifying this magnetic switch (series). Match the coil, the stud size and the bracket against your old switch – magnetic switches differ in how they pull and mount.
Maintenance & Replacement
Inspect for a hot terminal and a stuck plunger at every starting check. A switch that has begun to hang on draws current and cooks the solenoid, and the cook is what fails the start.
Confirm the terminals are tight and the coil reads on fit. A switch with a loose stud arcs at the post and the arc is what welds the contact.
Replace rather than clean a burned one. A switch whose contacts have pitted cannot be restored, only swapped.
Keep the correct magnetic switch for your starter on the bench. It is cheap next to a starter motor, and it is exactly the part missing when the engine will not crank today.
