Pipes tools & electrical mart suppliesoffers a compact range of limit switches. These limit switches are designed manufactured by avon engineering. Configurations in which these limit switches these are available are; in 2 no + 1 nc and 1 no + 2 nc contact configuration. The above switches are exactly the same size as regular 1 no + 1 nc limit switches, resulting in saving on space, and easily fit in standard as well as oil tight housings that use limit switches with just one pair of contacts.Distinct constructional features of these limit switches include; the body of the limit switch is totally enclosed made form high-grade fibre filled engineering plastics having rated insulation voltage of 500 v, . Ccontacts are made from bimetal silver cadmium oxide rated for 1 ampere thermal current [1 th]. All the moving contacts of normal action limit switches are electrically separated. The switches are provided come with built-in plastic protective cover as a standard feature and therefore save the cost of plastic protective cover.Enclosure of the switch is made from ddie cast aluminium housing with powder coated paint finish are used for the manufacturing of the enclosure of the switch. Standard enclosure has ip 55 degree of protection and oil tight enclosure ensures ip 65 degree of protection. Roller of the limit switch is made of delrin and lever of die cast aluminium is used for the manufacturing of the roller for robust operation.
