Parts Desk Insights
Best Use Case: Ideal for replacing a failed or worn horn push-button in a marine panel where you need a compact momentary on-off SPST switch with blade terminals.
Common Issues: If the horn doesn’t activate after installation, recheck the two blade-terminal wiring and the switch’s momentary behavior (it should return to off when released). Also confirm the panel opening is a true 1/2" mount hole and that the mounting stem is seated properly.
