Switches:

	PSW Tank Pressure Switch
	Distinguishing Features Inexpensive Compact High reliability 100% factory tested Built-in John Guest half cartridges
	Aquatec's PSW tank pressure sensing electrical switches are intended for in-line mounting as close to the hydropneumatic product water tank as possible. Its purpose is to turn off the Booster Pump when the tank is full. The normally closed switch can be factory pre-set at various shut-off pressures. The PSW, when used with a typical under-counter RO system, enables the hydraulic shut-off valve to open and close very reliably and positively. The PSW, with two John Guest half cartridges, is available for either 1/4" or 3/8" tubing. Optionally available are 1/4" or 3/8" Jaco elbows.

	LPS 340-G - Low Pressure Switch
	Distinguishing Features Inexpensive Compact High reliability Wiring and fittings included
	The LPS Low Pressure Switch electrically shuts off the booster pump if the feed water is interrupted. The LPS is designed to be mounted on the inlet side of the pump. Although the pump will not be damaged if operated without feed-water, pumping air into the membrane for extended periods can damage the module. We strongly recommend this device for applications where feed-water shut-off or interruption can occur. The LPS includes a wiring harness (not shown) that interconnects a pump and transformer.
