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.SpecificationsInput and output portsNPT 1/8"-27Mounting2 bolt holesAir flow30 CFM at 100 psi Exhaust flow25 CFMOperating force7 lb.

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.Linemaster Switch Company manufactures electromechanical, pneumatic, digital, linear Hall effect, and wireless foot switches for use in the industrial, medical, computer, and musical fields, among others. The company, founded in1952, is headquartered in Woodstock, Connecticut, and meets International Organization for Standardization (ISO) 2001:2008 and ISO 13485:2003 standards. ## Features - Single-stage, momentary action 3-way pneumatic foot switch for use with medium-duty air-operated devices - Steel housing for strength and durability - Non-skid base for stability and safety with two bolt holes for mounting to floor or equipment - Non-ferrous Internal valve, stainless-steel plunger, and Teflon (PTFE)-coated nitrile rubber O-rings for durability and resistance to corrosion - Line pressure up to 150 psi maximum ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005GRDAFO | | Actuator Type | Plunger | | Best Sellers Rank | #408,894 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #253 in Foot Switches | | Brand Name | Linemaster | | Circuit Type | 3-way | | Color | Black | | Compatible Devices | Air-powered tools and machinery | | Connectivity Protocol | X-10 | | Connector Type | Npt | | Contact Material | Stainless Steel | | Contact Type | Normally Open | | Control Method | Touch | | Control Type | Momentary | | Current Rating | 13 Amps | | Customer Reviews | 3.9 3.9 out of 5 stars (14) | | International Protection Rating | IP54 | | Item Dimensions | 3.07 x 2.76 x 1.54 inches | | Manufacturer | Linemaster | | Material Type | Steel | | Model | 3B-30A2-S | | Mounting Type | Surface Mount | | Number of Items | 1 | | Number of Positions | 3 | | Operation Mode | ON-NONE-ON | | Part Number | 3B-30A2-S | | Specification Met | Iso | | Switch Type | Flow Switch, Foot Switch, Pressure Switch, Temperature Switch | | Terminal | Screw | | UPC | 798167768634 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Linemaster - **Circuit Type:** 3-way - **Connector Type:** Npt - **Contact Type:** Normally Open - **Current Rating:** 13 Amps - **Item dimensions L x W x H:** 3.07 x 2.76 x 1.54 inches - **Material:** Steel - **Operation Mode:** ON-NONE-ON - **Switch Type:** Flow Switch, Foot Switch, Pressure Switch, Temperature Switch - **Terminal:** Screw ## Images ![Linemaster 3B-30A2-S Compact Airval Foot Switch, 3-Way Pneumatic, Single Pedal, Momentary, Single Stage, No Guard, Black - Image 1](https://m.media-amazon.com/images/I/518kcEa9PyL.jpg) ![Linemaster 3B-30A2-S Compact Airval Foot Switch, 3-Way Pneumatic, Single Pedal, Momentary, Single Stage, No Guard, Black - Image 2](https://m.media-amazon.com/images/I/519s2xxZ63L.jpg) ![Linemaster 3B-30A2-S Compact Airval Foot Switch, 3-Way Pneumatic, Single Pedal, Momentary, Single Stage, No Guard, Black - Image 3](https://m.media-amazon.com/images/I/51o8Sg0F1RL.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/15531610-linemaster-3b-30a2-s-compact-airval-foot-switch-3-way](https://www.desertcart.kg/products/15531610-linemaster-3b-30a2-s-compact-airval-foot-switch-3-way) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-05-11*
