Mechanical Float Switch 10A173

The Dayton 10A173 is a normally open mechanical float switch rated for 115 or 230 VAC operation. It provides automatic liquid level control for sump, sewage or water transfer pumps in residential and light commercial plumbing systems.

Replaces worn or failed float switches

Install this switch when an existing float mechanism sticks, leaks or no longer activates the pump at the correct level. The upgrade is worth it when the current switch cannot handle the 15 psi pressure rating required by the application.

Handles 15 psi pressure range

The switch comfortably manages level sensing in systems operating up to 15 psi. It is not suited for high-pressure vessels or applications that exceed this pressure limit.

Questions about this item

What mounting style does the Dayton 10A173 float switch require for tank installation?

The unit is a normally open mechanical float switch designed for 115/230VAC circuits with a 15 psi rating, so it mounts directly in the tank using its built-in float arm and cable tether.

Which wiring step on the 115/230VAC Dayton 10A173 switch do installers most often get wrong?

Confirming the supply voltage matches the 115 or 230 VAC rating before connecting the two-wire normally open contacts is the step most often missed, causing the pump to stay off.

When should the float mechanism on the Dayton 10A173 be inspected or replaced?

Inspect the float arm, cable tether and switch contacts annually or after any pressure event exceeding 15 psi; replace the entire switch if the float no longer rises freely or the contacts fail to close.
