Linemaster Switch Corporation is a leading manufacturer of industrial foot switches, including three models of air foot switches. These units protect critical electrical components in any environment, wet or dry, and a key advantage is isolation of the electrically live snap switch from the floor, which provides environmental protection.
With twin versions and full twin guards available, Linemaster air foot switches work for a variety of applications, with long lifespans.
Air-Seal, Vanguard, and Handbulb
For applications that need full guarding of the foot-switch pedal, some models will mount in the Linemaster Full Guard 522-B14. The customer may buy a foot-operated air bulb connected to a remote air-operated electric snap switch in momentary or maintained versions, with an SPDT snap switch; the air bulb can come in an optional metal housing. Ten-foot PVC tubing with a 1/8-inch inner diameter connects the foot pedal to the remote air switch, which itself has a 9/16-inch NF bulkhead mount. For high pull-out protection, the tubing is connected at the foot-switch end.
Other features of these units:
The three designs of Linemaster air foot switches are the Air-Seal, the Vanguard, and the Handbulb. Weighing half a pound and measuring 2.74 by 1.28 by 2.88 inches, the Air-Seal offers long, trouble-free life and is available with black tubing. With strong steel housing, the Air-Seal has two holes provided for rigid mounting to floors, equipment, or protective guards. Heavy gauge steel guards and an awareness cover are available on special request.
The Vanguard model weighs 1/5 of a pound and measures 4.59 by 1.26 by 2.77 inches, while the Handbulb model weighs 0.15 of a pound and measures 2.12 by 1.2 by 1¾ inches. All units have an electrical rating of 20 A 125-250 VAC, one horsepower 125 VAC, or two horsepower 250 VAC.
