Description

Measuring only 25 x 70 mm (1 x 2¾"), these FSW-130 Series compact switches are ideal for use where space is at a premium. Designed for use with water and oil, these switches are suitable for high volume OEM applications. They are ideal for coolant or lubricant flow monitoring in portable equipment and many other applications with space constraints. The switch points are based on water flow; oil switch points are dependent on the oils properties, and field testing is recommended.
