Electric Coils for Control Applications

Control coils include a broad spectrum of designs and applications. From the simplest relay coils, to complex power filtering equipment, to specialized coils for research. 

Coil designs can be as simple as small single winding bobbin coils or as complex as geometrically shaped, liquid intercooled coils with multiple windings and coil terminations‚Ķ from coils the size of a matchbox car to coil assemblies weighing over a ton. 

At Stimple & Ward, we manufacture them all. Each design is carefully reviewed and unique manufacturing processes & tools designed to get the job done.


Contactor Coil & Relay Coil Products

Send us a drawing or sample coil and we'll fabricate most any type of bobbin supported coil. With our in-house capabilities we can fabricate replacement and/or prototype coils quickly and economically. We also work with several fabricators to economical produce larger production lots.


Choke Coils & Blowout Coil Products

We manufacture many varieties of coils for high current applications, most notably of the edgewound variety. These coils range in size from a few ounces to several hundred pounds, and are constructed using copper strip .032"x.375" to .750x2.500" in cross section. With in house edgewinding equipment, hydraulic presses to 100 tons, and inert atmosphere annealing furnaces, we maintain tight control of quality and very competitive pricing. We can manufacture most any design, edgewound, or otherwise.
