FAQ

Q1: Is this switch a direct replacement for the OEM part on my Cummins K19 engine?
A1: Yes, part number 102057 is designed as a direct replacement for the OEM three-position push button switch on Cummins K19 and NTA855 engines. It matches the original mounting pattern, electrical configuration, and mechanical travel. We recommend verifying your existing part number against the cross-reference provided.

Q2: What are the electrical specifications for this switch?
A2: This is a standard three-position (Off-Run-Start) switch compatible with 12V and 24V electrical systems common on heavy-duty diesel engines. It features normally open contacts for the start position and maintained contacts for the run position. For specific current ratings, please consult your engine’s technical manual or contact our support team.

Q3: How should I test this switch before installation?
A3: Before installation, you can test the switch using a multimeter in continuity mode. In the “Off” position, all terminals should be open. In the “Run” position, the main power circuit should show continuity. In the “Start” (momentary) position, the start circuit should show continuity only while the button is held. Ensure the switch is disconnected from the battery during testing.
