Pole and Throw Specifications | |||
Your choices are... | |||
Single Pole, Single Throw (SPST) | Single pole, single throw switches make or break the connection of a single conductor in a single branch circuit. This switch typically has two terminals. It is commonly referred to as a "Single-Pole" Switch. | ||
Single Pole, Double Throw (SPDT) | Single pole, double throw switches make or break the connection of a single conductor with either of two other single conductors. This switch typically has 3 terminals, and is commonly used in pairs and called a "Three-Way" switch. | ||
Double Pole, Single Throw (DPST) | Double pole, single throw switches make or break the connection of two circuit conductors in a single branch circuit. This switch typically has four terminals. | ||
Double Pole, Double Throw (DPDT) | Double pole, double throw switches make or break the connection of two conductors to two separate circuits. This switch typically has six terminals and is available in both momentary and maintained contact versions. | ||
Other | Special throw types with more than 2 poles, such as switches designed to split loads into separate circuits (e.g. headlamp switch) | ||

Standards | |||
Your choices are... | |||
RoHS Compliant | Restriction of Hazardous Substances (RoHS) is a European Union (EU) directive that requires all manufacturers of electronic and electrical equipment sold in Europe to demonstrate that their products contain only minimal levels of the following hazardous substances: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl and polybrominated diphenyl ether. RoHS became effective on July 1, 2006. | ||
ELV Directive | End of Life Vehicles (ELV) Directive requires that certain automotive products be free (except for trace impurities) of mercury, cadmium, and lead as of 7/01/2003. Lead can still be used as an alloying additive in copper, steel and aluminum and in solderable applications. | ||
CE Mark | CE marking is a conformity mark used in the European economic community. | ||
CSA Mark | Products that bear a CSA Mark have been tested by the Canadian Standards Association (CSA) and meet applicable standards for safety and/or performance. These standards are written and administered by organizations such as the American National Standards Institute (ANSI), Underwriters Laboratories (UL), and CSA International. CSA Marks may appear alone or with indicators. CSA Marks that appear alone are used with products certified primarily for the Canadian market, to the applicable Canadian standards. CSA Marks that appear with the indicators “C” and “US” or “NRTL/C” are used with products certified for both the U.S. and Canadian markets, to the applicable U.S. and Canadian standards. | ||
UL Listing Mark | The UL Listing Mark indicates that Underwriters Laboratories Inc. (UL) has determined that representative samples of the product meet UL's safety requirements. These requirements are primarily based on UL's own published Standards for Safety. The UL Listing Mark is seen commonly on appliances and computer equipment, furnaces and heaters, fuses, electrical panelboard, smoke and carbon monoxide detectors, fire extinguishers and sprinkler systems, personal flotation devices like life jackets and life preservers, bullet resistant glass, and thousands of other products. | ||
WEEE Compliant | The Waste Electrical and Electronics Equipment Regulations (WEEE Regulations) is a European Parliament Directive with the aim of encouraging reuse, recycling, and recovery of electrical and electronic equipment, and to improve the environmental impact and performance of these equipments. This directive sets the requirements and criteria for the collection, treatment, recycling, and recovery of these equipments. It makes producers responsible for financing these activities, and retailers and distributors must provide means for consumers to return used or obsolete equipments without charge. | ||
Other | Other unlisted standards. | ||
