Linemaster Switch Corp.

Linemaster Switch Corp. Linemaster Switch Corporation is located in Woodstock, CT and is the leading manufacturer of foot operated controls in the world.

Linemaster Switch Corporation has been designing and manufacturing precision foot controls since 1952. Headquartered in Woodstock, Connecticut, Linemaster has grown into one of the world’s most recognized manufacturers of foot switches used in medical, laboratory, and industrial equipment. From this facility, more than one million switches are manufactured and shipped each year to OEM partners around the world. Linemaster focuses on the design and manufacture of both standard and custom foot control solutions built to meet the specific requirements of original equipment manufacturers. Many applications require precise, hands-free control in environments where reliability, responsiveness, and durability are essential. As customer needs and technology have evolved over time, Linemaster has met the challenge by continuing to expand its engineering capabilities to support a wide range of equipment and applications. Linemaster’s expertise is focused on the medical device industry. Foot controls are commonly integrated into surgical systems, diagnostic imaging equipment, dental units, laboratory instrumentation, and other clinical technologies where consistent hands-free operator control is critical. These environments often require components that are dependable, easy to operate, and designed with safety and cleanability in mind. To support global medical device manufacturers, Linemaster operates under a comprehensive quality and regulatory framework. The company maintains ISO 13485 certification, the internationally recognized quality management system standard for medical device manufacturing. Linemaster foot switches are also designed to meet a variety of global safety and regulatory requirements, including UL, CSA, CE, IEC, FCC, and RoHS compliance, depending on the specific product configuration and application. These certifications support integration into equipment that meets the strictest of international regulatory standards. Linemaster was also the first company to receive FDA 510(K) clearance for a (wireless or wired) foot switch, reflecting an early commitment to supporting medical device manufacturers operating within regulated environments and pushing the envelope of what’s possible. Linemaster continues to expand its portfolio of foot control technologies to support evolving equipment designs. Linemaster offers a wide range of control solutions, including RF wireless foot switch systems, USB-enabled controls, linear Hall effect switches, air-powered switches, electromechanical switches, and variable speed foot controls. Wireless foot switch systems provide equipment manufacturers with a cordless control option that may simplify cleaning procedures and help reduce potential tripping hazards associated with traditional cables. Engineering at Linemaster focuses on developing solutions that align with the operational and regulatory requirements of modern equipment. Foot switch designs often consider factors such as actuation force, electrical configuration, environmental protection, ergonomics, and durability. In medical environments, additional considerations may include patient isolation requirements, electromagnetic compatibility, fluid resistance, cleanability, and compliance with applicable medical safety standards. Continued investment in manufacturing capabilities, automated testing equipment, and facility improvements has strengthened Linemaster’s ability to support OEM partners worldwide. Each product is developed and tested to help ensure consistent performance in environments where dependable operator control is required. While Linemaster has grown significantly since its founding, the company continues to prioritize customer support, product quality, and long-term partnerships with equipment manufacturers. Linemaster’s engineering, manufacturing, and sales team work closely with customers throughout the design and development process to help ensure each solution aligns with the needs of the equipment and its end users. Today, Linemaster foot controls are integrated into equipment used in hospitals, laboratories, and industrial facilities around the world. As technology continues to evolve, Linemaster remains focused on advancing foot control solutions while maintaining the reliability, engineering standards, and manufacturing expertise that have defined the company for more than seventy years.

Two independent foot controls, one question. How many cords do you want running back to the equipment?
We build two twin Treadlite II models, and the answer to that question is the only real difference between them.
The TWIN T-91-S sits on a cast aluminum base with no wiring channel, so each pedal keeps its own run back to the equipment. Two cords, but you wire each side however the equipment needs it.
The TWIN T-91-SC48 uses a steel baseplate with a wiring channel built in. Both switches are joined inside that channel and share a single cord. One run instead of two, which is one less thing to trip over and one less thing to wear out.

SUN New England Conference 2026!☀️

Linemaster had the opportunity to host the Syteline User Network Conference for the second year in a row and what a success it was!

With 91 attendees we filled the room with successful, knowledgeable people making the educational sessions and networking opportunities so valuable! We definitely “stacked our knowledge”!

Thank you to Deborah Kettlety for organizing and planning this whole event, and to all of the speakers who took the time to share their insights, including two of our own employees, Sean Lewis, and Dennis Colburn.

Of course a huge shout-out to our sponsors Copley Consulting Group & PCG Services, and of course thank you to the attendees for the support, effort and participation. We couldn’t make this happen without the wonderful community to back it!

See you next year!💛

Three stainless foot switches, and one limitation that rules them out of certain jobs entirely. Quick Programming note: Starting today, we will move Foot Switch Friday to an every other week release schedule to make room for more content. See you again September 25th

Start with the good part. Manufacturers rated all three at IP68 and designed them for wash-down use, with corrosion resistance protecting against chemical exposure and a smooth surface aiding sanitation.
The SWANOS ships with no cordset at all. You run your own cable, and it comes with epoxy filled wire nuts to make that connection watertight. The SWANO3S has a piggyback plug on an eight-foot 18 gage cord. The SWANO38S has the same cord with bare leads for wiring into a panel.
Now the limitation. Every other Treadlite can be wired to run in reverse, complete at rest and broken when you press it. These three only close when you press them. If your equipment has to run until it gets a stop signal, this housing is off the table.

Plug in the switch. Plug your lamp into the back of it. Step on the pedal and the light comes on. Let go and it goes out.
That’s the piggyback, or household style plug, and it turns essentially any plug-in tool into a foot switch operated tool. The SC3 has a six foot cord, the SC3A has eight, and those two feet matter more than you’d think.
The other two use a quarter inch jack, the connector on tattoo machines, audio equipment, and dictation gear. The PS turns equipment on when you press it. The PSNC does the reverse, breaking the circuit instead, which makes it the odd one out in the whole Treadlite line.

The expensive version of this problem shows up late. Testing is done, tooling is finalizing, regulatory work is underway, and someone asks whether the units that were tested actually represent what will ship.
That question is called build equivalence. It is cheap to answer during program planning and costly to answer after, because the options at that point are supplemental testing, a bridging study, or repeating the affected activity.
Which tests need production representative units belongs in the schedule, not the post mortem.
New in the Linemaster Learning Center.
