Plastic Level Switches
A plastic level switch is a compact switch whose body and float are plastic, with a reed contact inside operated by the magnetic float. With no metal wetted parts it is preferred for some chemicals that attack stainless steel and in food-related applications.
The store range includes several plastic switch models with ½” connection and a ¾” water alarm switch. They are used in small tanks, machine reservoirs and leak warning; pressure and temperature limits depend on the plastic grade and are model specific.
Main Applications
- Chemical dosing and small treatment tanks
- Machine and coffee machine reservoirs
- AC drain and condensate trays
- Leak and flood warning
- Aquarium and water treatment tanks
Technical Data
| Operation | Magnetic plastic float + reed contact |
|---|---|
| Connection | ½” (switches), ¾” (water alarm switch) (product range) |
| Contact | NO / NC (by model, may change by inverting the float) |

| Body | Plastic (by model) |
| Float | Plastic, magnetic |
| Contact | Reed |
| Cable | By model |
Which material? The chemical resistance of a plastic switch depends on the medium; in acid, alkali or solvent applications check material compatibility in the model’s datasheet. A reed contact does not supply a pump directly.
