Frequently Asked Questions
Q: What does the N84C low pressure contact switch do?
A: The N84C pressure switch monitors incoming water pressure to your booster pump. When pressure drops below a safe threshold — due to a blocked filter or insufficient water supply — the switch automatically cuts power to the pump motor, protecting it from running dry and preventing potential damage to your water filtration system.
Q: Is this pressure switch compatible with reverse osmosis (RO) systems?
A: Yes. The N84C low pressure switch is designed for use with standard 1/4" quick-connect fittings commonly found in reverse osmosis and water filter setups. It works with most booster pump motors used in these systems.
Q: What voltage does the N84C pressure switch support?
A: The N84C operates at low voltage — below 50V AC or 75V DC — making it safe for use in residential water filtration and pump systems. It meets EU Low Voltage Directive (LVD) requirements.
Q: Does this switch come with installation accessories?
A: No. The package includes only the N84C Pressure Switch itself. Any tubing, connectors, or other accessories shown in product images are not included and must be sourced separately.
