Switches for frequency

Limit value switch for frequency (alternating voltage)


Limit value switch RW5
  • Limit value switch for AC voltage
  • Simple application; for rough environments
  • Limit value freely adjustable by drum scale
  • Open-circuit or closed-circuit devices available
  • Compact and robust construction
  • Operating status indication by integrated LED


Limit value switches of type RW5 monitor electrical measured variables. The integrated relay switches when the actual value present reaches the set target value. Open-circuit devices can also be equipped with a self-latching feature as an option. Its compact and robust design, as well as the relevant shipbuilding approvals, make this product ideal for marine applications.
