Motor Starters, Honeywell Micro Switch Limit Switches & Heavy-Duty NEMA Wiring Devices
Keep production lines, air handlers, elevators, and machine tools running with exact replacement contactor coils, contact kits, snap-action limit switches, and industrial-grade Twist-Lock® receptacles and plugs.
From Furnas Motor Starters to Honeywell Micro Switches & Hubbell Twist-Locks
A single pitted silver-cadmium contact set, a burned-out 24VAC/120VAC/208VAC/480VAC magnetic starter coil, or a sheared limit-switch roller arm can idle an entire packaging line or rooftop mechanical system. Rather than replacing an entire motor control cabinet, our counter specialists identify and supply exact drop-in replacement coils, thermal overload heater elements, contact renewal kits, and snap-action switches.
We have served as a factory-authorized and legacy cross-reference source for Furnas Electric (now Siemens), Cutler-Hammer/Eaton Freedom & A200 series, Honeywell Micro Switch, Linemaster industrial foot switches, and commercial/hospital-grade wiring devices from Hubbell, Leviton, Bryant, and Eagle for decades.

Counter Identification Guide for Motor Controls & Limit Switches
- For magnetic starters: Record the manufacturer, NEMA Size (00 through 5) or IEC amp rating, catalog number on the nameplate, and the 3- or 4-digit suffix stamped directly on the molded coil.
- For thermal overload heaters: Check the motor nameplate Service Factor (1.0 vs. 1.15) and Full Load Amps (FLA), plus the ambient temperature of the starter enclosure.
- For Honeywell Micro Switch units: Bring the old switch to our counter so we can match pin plunger overtravel, mounting hole centers, and die-cast housing seal boots.
- For locking plugs and connectors: Read the NEMA designation stamped on the face around the blades (e.g., NEMA L15-30P) rather than guessing from blade count alone.

Counter Q&A: Motor Controls, Micro Switches & Wiring Devices
Can you cross-reference discontinued Furnas Electric motor starters and replacement contact kits?
Yes. Furnas Electric was acquired by Siemens, and many legacy Furnas Class 14, Class 16, Class 42, and InnoveE series starters remain in daily service across New England facilities. Our counter cross-references legacy Furnas part numbers to exact replacement contact kits, coils, and thermal overload heater elements.
What makes a Honeywell BZE6 enclosed switch different from a standard BZ basic micro switch?
A standard Honeywell BZ switch has an phenolic body for mounting inside a clean control panel, whereas the BZE6 series encloses the precision snap-action mechanism inside a rugged die-cast aluminum housing with a 1/2"-14 NPT conduit hub and elastomer seal boot for exposed machine-tool and conveyor environments.
Do you carry Hospital Grade receptacles and Wiremold surface metal raceway for medical and school retrofits?
Yes. We stock UL 498 'Green Dot' Hospital Grade duplex, GFCI, and isolated-ground receptacles from Hubbell, Leviton, and Bryant, as well as Wiremold 500, 700, 2000, 3000, and 4000 surface raceway channels, elbows, and device boxes for masonry school and hospital walls.
