Specifications
   Working Pressure Range       The maximum allowable pressure at which a system or piece of equipment is designed to operate safely. This is the pressure range the user will operate in. It is common practice that this value should not exceed 75% of the devices maximum rated range. For example, if the device has a maximum rated range of 100psi then the working range should not exceed 75 psi. 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
   Switch Point Range       The range the switch operates in that is variable and sets the upper and lower set points. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Primary Material of Construction
   Material:      The primary material the air switch is made from.
   Your choices are...         
   Acetal       Acetal polymers are semi-crystalline. They offer excellent inherent lubricity, fatigue resistance, and chemical resistance. Acetal suffers from outgassing problems at elevated temperatures, and is brittle at low temperatures. Glass-filled and added lubrication grades are available; flame-retardant grades are not. Brand names include Celcon® (Hoechst Celanese), Delrin® (DuPont), Thermocomp® (LNP), Ultraform® (BASF), and Acetron® (DSM). 
   PVC       Polyvinyl chloride (PVC) is a widely used material that has good flexibility, smooth surface, and nontoxic qualities. Some grades are used in food and chemical processes due to the inert nature of PVC. Brand names include: ACP® and Dural® (Alpha Gary), Geon® (Geon), Benvic® (Solvay), Flexalloy® (Teknor Apex). 
   CPVC       Chlorinated polyvinyl chloride (CPC) a higher type grade of plastic commonly used for hot/cold water distribution, sprinkler piping, and some chemicals. Suitable for high temperatures. 
   Nylon - Polyamide       Thermoplastic resin used for mechanical parts. Can be extracted, cast or injection molded. The most common commercial grade is Nylon 6/6. Can be glass-filled to further enhance structural impact strength and rigidity. 
   PEEK       Polyetheretherketone or polyketones. PEEK is a semi-crystalline thermoplastic with excellent mechanical properties. 
   Polyethylene (PE)       Commodity thermoplastic that is soft, flexible and tough, even at low temperatures, with outstanding electrical properties but poor high temperature resistance. It also has very good chemical resistance but is prone to environmental stress cracking. It has poor UV resistance (unless modified) and poor barrier properties, except to water. 
   Polypropylene (PP)       Polypropylene is a thermoplastic material exhibiting excellent cold flow, bi-axial strength, and yield elongation properties. It is similar to PVC but can be used in exposed applications because of its resistance to UV, weathering, and ozone. 
   PVDF       Polyvinylidene fluoride (PVDF) is a melt-processable fluoropolymer. It is similar in properties to other fluoropolymers, but has better strength and lower creep. PVDF has good wear resistance and excellent chemical resistance, but does not perform well at elevated temperatures. Brand names include: Kynar® (Elf AtoChem). 
   Aluminum       Aluminum is a bluish, silver-white, malleable, ductile, light, trivalent, metallic element that has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation. 
   Brass / Bronze       Brass comes with good strength, excellent high temperature ductility and reasonable cold ductility, good conductivity, excellent corrosion resistance, good bearing properties and low magnetic permeability. Sintered bronze is a porous material, which can be impregnated with oil, graphite or PTFE. Not suitable for heavily loaded applications but useful where lubrication is inconvenient. 
   Cast Iron       Cast iron refers not to a single material, but to a family of materials whose major constituent is iron, with important trace amounts of carbon and silicon. Cast irons are natural composite materials whose properties are determined by their microstructures - the stable and metastable phases formed during solidification or subsequent heat treatment. The major microstructural constituents of cast irons are: the chemical and morphological forms taken by carbon, and the continuous metal matrix in which the carbon or carbide are dispersed. 
   Ductile Iron       Ductile iron retains cast iron's machinability and corrosion-resistance, and provides additional strength, toughness, and ductility. Although its chemical properties are similar to those of cast iron, ductile iron incorporates significant casting refinements, additional metallurgical processes, and superior quality control. 
   Copper       A common reddish metallic element that is ductile and malleable and is one of the best conductors of heat and electricity. 
   Stainless Steel       Stainless steel is chemical and corrosion resistant and can have relatively high pressure ratings. 
   Steel       Steel is a commercial iron that contains carbon in any amount up to about 1.7% as an essential alloying constituent. It is malleable when under suitable conditions, and is distinguished from cast iron by its malleability and lower carbon content. 
   Other       Other unlisted, specialized, or proprietary material.
