- Questions

What's the difference between mechanical and electronic float switches?

Mechanical switches use pivoting float arms activating internal contacts. Electronic switches use solid-state sensors with no moving parts, offering longer service life and no mechanical wear. Gold Coast boaters choose electronic for reliability, while mechanical switches provide proven performance at lower cost.

How high should float switches activate bilge pumps?

Set activation at 50-75mm above bilge floor, allowing sufficient water accumulation for pump priming while preventing excessive water buildup. Ensure float has clearance for full travel without obstruction. Brisbane boaters should test switches monthly verifying proper activation and pump operation.

Can one float switch control multiple bilge pumps?

Standard float switches handle single pump loads only. Multiple pumps require individual switches or relay systems splitting control signals. Tweed Coast boaters with high-capacity bilge systems should use separate switches for each pump, ensuring redundancy if one switch fails.

Why does my float switch fail to activate the pump?

Common causes include corroded contacts, debris preventing float movement, incorrect wiring, or switch positioning too high. Check float moves freely, connections are clean and tight, and activation height allows proper water accumulation. Our Gold Coast team recommends annual switch inspection with contact cleaning and float mechanism testing.
