FAQs
What types of electrical switches do you supply and install in Corryton?
We carry a full range of residential, commercial, and industrial switches, including standard single-pole, three-way, four-way, dimmers, smart Wi-Fi/Z-Wave models, heavy-duty knife switches, motor-rated disconnects, and precision snap-action microswitches. All products are sourced from Tier-1 manufacturers, UL-listed, and rated for the specific voltage and current required by your application.
How do I know which switch is best for my application?
Start by determining the circuit voltage, current load, and control style you need (on/off, momentary, or variable dimming). Our Corryton engineers can perform a site visit or review your schematics, calculate load demands, and recommend a switch with the proper amperage rating, insulation class, environmental sealing (NEMA/IP), and lifecycle expectancy. We then provide a written specification sheet for your approval before ordering.
Do your precision-engineered switches meet national safety standards?
Yes. Every switch we install is UL or ETL certified for the United States and complies with the latest NEC (National Electrical Code) requirements. Industrial devices additionally meet IEC and CSA standards where applicable. We maintain full documentation, including manufacturer data sheets and conformity certificates, which are provided to you with the final project packet.
Can you retrofit modern switches into older Corryton homes or facilities?
Absolutely. Our team frequently upgrades legacy wiring systems, replacing outdated toggle or mercury switches with modern, code-compliant devices. We assess existing wiring, box depth, and grounding, then supply compatible retrofit plates or smart-switch adapters. All work is performed under the Tennessee State Electrical Code and includes a final inspection and permit closure.
What is the typical lead time for ordering custom or specialty switches?
Standard residential and commercial switches are stocked locally and can usually be installed within 1–3 business days. Custom-engraved, explosion-proof, or special-finish devices may require 2–4 weeks depending on manufacturer backlog. We provide a firm delivery schedule at the time of quotation and update you proactively if factory lead times change.
Do you offer maintenance and troubleshooting support after installation?
Yes. Every switch installation includes a 12-month workmanship warranty. We also offer optional preventive maintenance plans that cover annual torque checks, infrared hot-spot scans, and function testing. If a switch fails, our Corryton service team can typically respond within 24 hours to diagnose, repair, or replace the unit, minimizing downtime.
