LSMS Level Switch – Magnetic Side Mounted
Compact, rugged magnetic float switch with snap-action dual-magnet design — rated to 180°C and 20 Kg/cm².
LSMS switch is compact & rugged with a free-moving float and switch assembly in non-magnetic material. It includes dual magnets — one on the float arm and one in the switch enclosure. A change in liquid level brings like poles opposite, causing a repulsion force that gives changeover contacts with snap action. Available in Standard, High Temperature and Adjustable Differential variants.
