Limit Switches

Shri Tulsi Switchgear offers "STS" Limit Switches designed to convert mechanical motion into an electrical control signal. Meeting hi-tech requirement of switching technology demanding sophistication, perfection and reliability, these are designed for accuracy of operation, long mechanical life to withstand shock and vibration condition and to keep operating safety in highly contaminated atmosphere at a temperature of-20°C to + 65°C. Mechanical motion is generally in the form of a cam, a mechanical component moving towards a predetermined position. The cam engages the limit switch roller lever or plunger and in turn makes or breaks an electrical contact inside the switch. The electrical control circuit is used to limit, position or reverse motion travel or to initiate another operating sequence. 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, rated at 10 A, are made of special silver alloy, which ensure satisfactory operation even at low voltage. The normal roller levers are also available with highly grade wear resistant phenolic and thermosetting plastic moulded rollers.
