Troubleshooting Case

Problem: Caterpillar 345D excavator dash warning lights stay on after engine start; horn and trumpet button unresponsive.

Cause: Water ingress into 3G-2720 switch caused internal corrosion, keeping circuit closed.

Solution: Replace old switch with new IP65-rated Growshine 3G-2720, add dielectric grease on terminals, reroute drain hose away from dashboard. Downtime reduced from 2 days to 30 minutes.

Product Knowledge

Trumpet button switches are momentary push switches that complete the horn circuit only while pressed. Growshine uses silver-plated contacts for low resistance and thermoplastic housing for flame-retardant performance. The 28 mm mounting diameter matches most OEM panels, making installation plug-and-play without additional adapters.
