The SOR ® 1710 Side Mounted Level Switch is a horizontally mounted, float-operated
level switch. The 1710 is suitable for plant and OEM applications where open or closed
contacts are required to signal presence or absence of liquid at a discrete level.
When the liquid rises, the float extension arm moves a magnet which repels an internal
magnet de-actuating a microswitch. When the liquid level falls, the float extension arm
moves the magnet in the opposite direction, actuating the microswitch.
The 1710 is recommended for use in clean liquids only.
