Havells Electrical Switches Dealers in Lawrence Road, Delhi

SURDHI® Limit Switches have been designed to convert mechanical motion into an electrical contr The switches meet the Hi-Tech requirement of Switching technology demanding Sophistication, P and Reliability. These are designed for accuracy of operation, long mechanical life to withstand s vibration condition and to keep operating safely in highly contaminated atmosphere at a temperatun to + 65°C. Mechanical motion is generally in the form of cam, a mechanical component moving ti predetermined position. The cam engages the limit switch roller Lever or plunger and in turn makes an electrical contact inside the switch. The electrical control circuit is used to limit, position or reven travel or to initiate another operating sequence. Sailent Features : Liberal spacing is provided around the terminal for easy wiring. The enclosure is compact, dust &vermin proof with pressure die cast aluminium. The switches with IP-67 protection are completely oil tight, water tight with a shaft seal between the lever and the Dust Proof. These are designed for accuracy operation, Long mechanical life and to keep operation safety at a temperature - 20°C to + 65°C. These are having an outstanding long mechanical life of 20 million switching operations. The mechanical switching accuracy is maintained 0.01 mm even after 10 thousands switching operation. The Contact blocks can be taken out easily and replaced without risk of changing the operating characteristics of limit switches. Limit Switches are also available with a transparent protective cover to prevent dust setting on the contacts. Contacts are made up of special silver alloy which ensure satisfactory operation even at low voltage. Contacts are rated at 10 Amps.
