Limt Switches "STS"
Limit Switches have been designed to convert mechanical motion into an
electrical control signal. The switches meet the 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
-20oC to +65oC.
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
sequence.
