 L090SA Series Swing Arm Level Switch   Printer Friendly Version
The L090SA is a single and dual set point level switch designed for dirty applications where particle entrapment is a problem. Manufactured to customer specified switch points, the L090SA was originally developed for commercial dishwashers to alleviate the common problem of particle jamming in a conventional float switch movement. This device has adequate clearance between the moving arm and the mounting stem to provide a self cleaning action on each actuation. It is available in brass and stainless steel versions with a wide variety of mounting sizes and styles.
