Overview – SWITCH-TOGGLE (DPDT)-3C 308-0406
For Cummins electrical and operator control circuits as the DPDT selector switch, the Cummins SWITCH-TOGGLE (DPDT)-3C 308-0406 provides the correct fit and performance expected from a genuine-spec replacement.
Parts Characteristics
A DPDT (double-pole double-throw) toggle switch that selects between two circuits or operating modes in the machine’s control layout. It carries the control current for the function it governs, so a switch with a clean contact set and a firm detent keeps the selection positive and the circuit free of intermittent drop-outs.
Applicable Models & Applications
Fitted to Cummins control positions specifying this DPDT switch. Match the terminal arrangement, current rating and lever style against your old switch or the parts book – DPDT switches with the same body can carry different contact ratings.
Maintenance & Replacement
Inspect the switch for a loose lever, cracked base or corroded terminals at every electrical service. A switch that wobbles in its seat makes contact intermittently, and intermittent control faults are the hardest to find once the cover is back on.
Confirm the terminals are tight and the seals intact. A switch that lets moisture into the base corrodes the contacts from the inside, and the first symptom is a function that works only when you tap it.
Replace with the correct rating, not just the correct shape. A switch that looks identical but carries a lower current rating fails under load and can take the circuit it protects with it.
Keep common DPDT switches for your model on the bench. They are inexpensive, they fail quietly with age, and they are exactly the part missing when a control function needs to come back today.
Price Reference (USD)
