Compliance and Restrictions

  • This product has been certified by a third party to be compliant with the “Safe Drinking Water Act” requirements for low lead in potable (human consumption - drinking and cooking) and non-potable water applications (non-human consumption).


This liquid level switch is designed to easily convert from high to low alarm, or from pump-up to pump-down operation by rotating 180°. It mounts to the outside of a tank or vessel using an NPT coupling, or to the inside using a bulkhead fitting (UNC/UNF). The dependable, encapsulated, magnetically coupled dry reed switch delivers more than 5 million switching cycles at a rated electrical load to control motor starters, contactors, solenoids, and relays.
