Coolant Level Switches

Passive level switches are devices that monitor a fluid level based on a non-contact magnetic float:

• Protect systems from overfilling or damage
• Control activation and deactivation of devices to avoid their damage due to high or low fluid level
• Activate devices based on a fluid level (e.g., warning light)

Available in different contact arrangements and mounting variants

• Horizontally mounted (side), SPST normally closed, normally open - finger switch
• Vertically mounted (top, bottom), SPST normally closed, normally open, with drain plug (bottom mounted) - float switches

• SMP makes floats in a broad range of materials to provide compatibility with different media (e.g., diesel, engine oil, hydraulic oil, ethanol, coolant, brake fluid, etc.) and different mounting port materials
• Available with different connector types and electrical contact materials
• Available in a range of operating pressures and temperatures
• Designed for a long service life and extreme working conditions
• SMP offers a wide range of configuration options that can be optimally adapted to customer requirements
