GET CUSTOM-BUILT CONTROL STATIONS WITH
off-the-shelf turnaround times.
The FlexStation offering is a complete system of interchangeable control
station devices that can be quickly and easily assembled on-site into
hundreds of configurations, to meet your specific application requirements.
Applications
FlexStation factory-sealed control stations are installed in a rigid metallic conduit
system for surface mounting adjacent to or remote from equipment being
controlled. They are used:
■ in conjunction with magnetic starters or contactors for remote control of motors
■ to prevent arcing of an enclosed device from causing ignition of hazardous
atmosphere(s) outside the enclosure
■ in industrial areas where the atmosphere may contain hazardous gases and/or
dusts, such as chemical plants, oil and gas refineries, paint and varnish
manufacturing plants, gasoline bulk loading terminals, grain elevators, grain
processing industries, coal processing or handling areas, and metal handling
or finishing areas
■ in nonhazardous areas where sturdy, durable enclosures are required
A COMPLETE SYSTEM OF DEPENDABLE DEVICES AND COMPONENTS

- Pushbuttons, including
single and double maintained and momentary
buttons (red/green/black)
