This Linemaster 3B-30A2-S Compact Airval pneumatic foot switch has a steel housing, input and output ports, and a 3-way, corrosion-resistant internal air valve. This foot switch is suitable for use in applications in which users need hands-free, on-and-off power activation. It provides single-stage, momentary action for quick-release termination. Air flows through the foot switch when the plunger is depressed, stops flowing when the plunger is released, and exhausts back pressure on its output side. It has a steel housing for strength and durability and standard 1/8"-27 National Pipe Taper (NPT) input and output ports. The 3-way internal valve has a non-ferrous body, a stainless-steel plunger, and Teflon (PTFE, polytetrafluoroethylene)-coated nitrile rubber O-rings for durability and resistance to corrosion. The non-skid base gives the foot switch stability to help prevent sliding on smooth floors, and has bolt holes for mounting to the floor or equipment. This foot switch is compliant with the Restriction of Hazardous Substances (RoHS) directive. A filtered and lubricated air supply is required for best operation. A heavy gauge steel guard is available for this product (contact manufacturer). This momentary action air-operated foot switch is suitable for medium-duty operations in the food equipment, woodworking, metalworking, textile, stamping, and printing industries, among other applications.

Foot switches are used to turn on and off electrical devices and may also provide control over the device's speed and mode of operation. They come with up to three pedals and can have a maintained, momentary, variable, or anti-trip switch action. For maintained action switches, one press of the pedal controls the power, whereas momentary action switches require constant pressure on the pedal for power. Variable action switches (also called foot potentiometers) function similarly to momentary action switches, but also provide control over the connected device's operating speed. Anti-trip action switches require users to release a safety latch before pressing down for momentary action. Foot switches vary in their contact specifications, amp ratings, plugs and receptacles, and material construction to suit different applications, device amperages, plug configurations, and environments. Foot switches are commonly used with power tools, sewing machines, musical instruments, dental equipment, and lighting, and in the construction, laboratory, production, and medical fields, among others.
