Automatic Marine Float Switch

The Rule 40A-GRA is a new automatic marine float switch designed for bilge-pump activation on boats and other marine vessels. It operates across a 12 VAC to 32 VAC range, covering 12, 24 and 32 VAC systems. The switch carries the manufacturer reference 8.300 and contains no user-serviceable parts.

Voltage-Range Compatibility

This single-pole device only closes its circuit within the stated 12 VAC to 32 VAC window; it will not function on DC supplies or on AC voltages outside that band. Buyers who need a DC-rated switch or a wider voltage span must select a different part.

Questions about this item

What does the 8.300 rating mean when the float switch is installed in a bilge system?

The 8.300 designation identifies the Rule 40A-GRA as an automatic marine float switch designed to activate a pump when water reaches a set level and shut it off when the level drops.

How do the 12VAC, 24VAC and 32VAC ratings limit the control voltage I can use with this switch?

The switch is rated for control circuits up to 32 volts AC; applying a higher voltage would exceed its rating and could damage the contacts.
