Dayton 10A174 Float Switch

The Dayton 10A174 is a mechanical float switch designed for liquid level control in pump systems. It operates on either 115 VAC or 230 VAC supply voltage. The unit features a normally open contact configuration that closes as the liquid rises. This accessory is intended for use with compatible pumping equipment.

Suits single-pump level automation

This switch suits installations requiring automatic start and stop of a single pump based on fluid height. It is not for applications needing a normally closed contact that opens on rise. Buyers who want adjustable differential settings should look at alternative control types. The 15 psi pressure rating also limits use to low-pressure tanks and sumps.

15 psi maximum pressure rating

The 15 psi rating is the primary specification that determines whether this switch fits the system. It defines the maximum hydrostatic pressure the float mechanism can withstand without failure. Systems operating above this limit require a different pressure-rated device. Verify the tank depth and fluid density against this figure before purchase.

Questions about this item

How often should the mechanical float mechanism on the Dayton 10A174 be inspected or replaced?

Inspect the float mechanism periodically for debris buildup or wear on the moving parts; replace the switch if it fails to actuate reliably at the 15 psi setting.

What is the maximum pressure the Dayton 10A174 can handle before the switch becomes the limiting factor?

The switch is rated for 15 psi; sustained pressure above that level can prevent proper actuation or damage the internal mechanism.

Does the Dayton 10A174 generate noticeable heat or noise when powered continuously at 115 or 230 VAC?

As a mechanical float switch it has no motor or electronics, so it produces no audible noise and negligible heat during continuous operation.
