The durable construction of these reed switch designs ensures long, trouble-free service. Because the effects of shock, wear and vibration are minimized, these hermetically sealed level switches provide precise repeatability with no more than 1% deviation. The level switch actuation points remain constant over the life of the unit.

Ideal for shallow tanks or restricted spaces, or for any low-cost, high volume use. LS-3 Series are available in FDA/NSF compliant materials upon request, consult Gems™ for details.

NEW LS-3 MICRO: Gems’ newest addition to the LS-3 series family is the LS-3 Micro. It is the smallest LS-3 series switch available. These units are ideal for potable water, medical devices and other compact appliances such as printers. Gems LS-3 Micro float enables use in lighter-than-water fluids. These switches are also made with FDA compliant material, which expands the scope in which these floats can be used.
