Pneumatic Switches    A pneumatic switch regulates compressed air to control tools or equipment. When the pedal is pressed, a valve opens and air moves through tubing to power the device directly. There is no electricity at the pedal at all.  Because the signal is purely air, pneumatic switches are especially useful in places where moisture, ...

A Record Breaking Year Built on Consistency   2025 marked an important milestone for Linemaster. For the first time, consistent progress was sustained across an entire calendar year. This month also marked the twenty-first consecutive month of outperforming the same month from the year prior.   The level of consistency reflects steady execution across the company. It speaks to coordination ...

Function and Core Concept   An interlock prevents both sides of a foot switch from being activated at the same time. This applies to two pedal designs as well as rocker treadles that rotate around a center axis. The purpose is to stop two competing functions from running together, such as forward and reverse on a ...

Medical Foot Switches Must Match the Device They Support  Medical foot switches are usually custom, even when they appear similar from the outside. The way the switch communicates with the device can vary significantly from one application to another. Differences may involve:  There is no single industry standard that governs all of these details. Each ...

Benefits of the Flip-Up Design  The main benefits are ease of cleaning and added travel for variable control. With the treadle flipped up, there are no parts to block the surface, so cleaning is straightforward on both the cover and the channel. That smooth angled surface contributes to a fluid resistant design by making it ...

What a Hall Sensor Does  A Hall sensor reads the position of a magnet built into the pedal. As the treadle moves, the sensor picks up the change in magnetic field and turns it into an electrical signal.  Unlike a microswitch, which gives a distinct click when it’s activated, a Hall sensor moves silently. That ...

How Wireless Foot Switches Manage Power and Battery Life   In a wireless foot switch, the processor and the communication system use the most power. The communication device, typically the radio chip that enables wireless transmission, is one of the highest power consumers in the circuit.  To conserve energy, the circuit is designed to complete its ...

What Is an Air Switch? An air switch is a non-electric device that controls the flow of compressed air to power a pneumatic tool or mechanism. Unlike electrical switches, air switches don’t involve any circuitry or wiring. When the actuator is pressed, a valve opens that allows for compressed air to flow through tubing and ...

Inside a foot switch, the PCBA acts as the core of the circuit. It connects all electrical components to make sure the switch performs as intended. A PCB is simply a bare board, while a PCBA includes all the mounted components that make the circuit function. Whether the goal is signal control, variable output, or ...

What’s the Actual Risk if a Foot Switch Activates Unintentionally   Even in controlled settings an unintended press of a foot switch can trigger motion or power in ways that put people and equipment at risk.  In medical applications an accidental press could cause bodily injury. Guards help reduce that risk, but other issues can still ...
