LS-1700/1750/1755 Single-Point Level Switch

Small compact level switches combines reliability with low cost. 

The LS-1700 Series Single-Point Level Switch unit is equipped with a hermetically sealed SPST 20 VA reed switch and is operated by permanent magnets within the float. As the float is raised and lowered with changing liquid level, the hermetically sealed single point level switch closes as the float comes into proximity of the reed switch. 

The switch logic can be reversed on most models by inverting the float on the stem via a removable float retaining clip. The 20 VA switch is suitable for most solid state control circuits, by using a relay interface the switch can be made capable of switching higher current loads. The unit is easy to install and can be top or bottom mounted. 

Using an extension pipe and proper sealing techniques the unit can be extended into the tank for high, intermediate, and low level actuation points.

The LS-1700 brass/buna version is ideal for low hydraulic fluid warning and other hydrocarbon applications. It can be factory custom configured for volume OEM applications and used as a water or oil level switch. 

LS-1750 Series Single-Point Level Switches are ideal for shallow tanks or restricted spaces, or for low-cost, high volume use. Rugged construction suitable for most corrosive liquids, and for high temperatures and pressures. All-stainless steel material of construction complies with FDA food contact regulations.
