Parts Desk Insights
Best Use Case: Choose this SuperSwitch float switch when you want a heavy-duty, non-mercury float control for a bilge pump and value easier maintenance thanks to the removable base.
Common Issues: If the switch won’t trigger as expected, re-check float clearance/positioning and confirm the switch is mounted securely to allow normal rise/fall movement. Also inspect the wiring condition and routing around the bilge area to reduce strain or abrasion.
