Certified for Demanding Workspaces  Industrial environments require more than rugged equipment. They require proof that safety and performance standards are consistently met. Linemaster operates under ISO 13485, a standard recognized internationally for medical devices but equally powerful in demonstrating quality management for industrial applications. This means the same level of rigor that governs medical-grade products ...

What Defines a Medical Foot Switch A medical foot switch is not just another control device. In healthcare environments, it is an essential part of equipment performance. Linemaster’s medical foot switches are engineered to meet strict requirements for hygiene, reliability, and compliance. Making them a trusted choice for operating rooms, imaging labs, and patient care ...

Common Uses of Foot Switches  Foot switches are designed for hands free operation, which makes them especially useful in environments where efficiency, safety, and accuracy are priorities. In medical settings they are used to control surgical tools, dental chairs, and imaging systems where sterile operation is essential. In industrial applications they help run factory machinery, ...

On paper, it sounds ideal: a custom solution made for your application, ready to plug in and go. But what most people don’t realize is how long that can take, what it costs, and why even simple changes aren’t always so simple.  Here’s a breakdown of what actually goes into building a special switch, what ...

How Potentiometers Works    A potentiometer is a variable resistor. A fixed resistor always holds one value, but a potentiometer changes that value as it moves. Inside, there’s a resistive track and a moving contact called a wiper. As the wiper travels along the track, it changes how much resistance sits between each end of the ...

When Does a Foot Switch Become “Special”?    A switch becomes special the moment it deviates from our standard catalog offering.  That could mean:  This might seem like small asks, but each one changes how we build and track that part. If it’s no longer the off-the-shelf version we usually ship, it’s flagged and handled as ...

Not All Customization Is Created Equal    Not every request falls into the same bucket. That is where confusion usually starts.  A standard product is something we already build, test, and stock. these move through production quickly because everything has already been designed, validated, and approved. On the medical side, however, none of our foot switches ...

What We Test In House   Not every test needs to happen in a third party lab. We handle quite a bit of durability and electrical validation right here, including:  We have even developed specific in-house methods, like submersion testing in saline water, to help validate water protection. And we have built custom setups for real ...

What is a Single-Stage Switch? A single-stage switch does one job. Press the pedal, and one function activates. Inside the treadle, there’s just one switch, usually a microswitch or a Hall sensor. If it’s a microswitch, you’ll hear and feel a click when it actuates. The actuation point is typically set around halfway through the ...

What Do “Poles” and “Throws” Actually Mean?  A pole refers to the number of separate inputs on a switch controlled by a single actuator. A throw refers to how many different outputs each input can connect to.  For example:  As you move from single to double pole, the number of circuits a switch can control ...
