Series 20 Level Switches



Series 20  Level SwitchesThe Compac Engineering ERECTA SWITCH Series 20 Pump Control System is designed to handle industrial pump control like switching electrical contactors, solenoid valves, and motor starters. Series 20 switches use the Yaskawa Control Bestact hermetically sealed switch element.

All Compac Engineering ERECTA SWITCH series 20 switches can operate with a 3 amp inductive load!

20 Series assemblies are built from stock part. Compac Engineering ERECTA SWITCH components make length, switch action, switch position, mounting and electrical interface optional.

20 Series switches and pump control configurations are available in 120VAC. 240VAC and DC industrial control applications where compact size, corrosion resistance, long life are important for high-low pump control such as applicatins as silver reclamaition, car washes, electroplating, semiconductor processing, gas tanks, diesel tanks, etc...
