20 Product Group

The ERECTA SWITCH
Series 20 Pump Control System is designed to handle industrial
control jobs like switching contactors, motor starters and
solenoid valves. 20s use the Yaskawa Control Bestact™
hermetically sealed switch element.
20s use a common
parts set and assembly style. Complementary ERECTA SWITCH
components make length, switch action, switch position, mounting
and electrical interface a matter of choice. Disciplined assemblies
and precision parts make field repairs practical.
20s switches and
pump control configurations are valuable in AC and DC industrial
control applications where compact size, corrosion resistance,
long life and repairability are important for high-low pump
control, electroplating, semiconductor processing, diesel
day tanks, etc...
