The associated document.Switches (Limit switch), the term limits is one of the most important devices used in industrial automatic control systems, we came to know the Lord. -Totwit (Limit switch).-Totwit (Limit switch) is a switch that limits the distance. The work relies on external pressure of thapthi do, such as push button, or press the buttons that came to cam and as a result, a page that is attached to the stem and butt. Open-close by the rhythm of the collision.The advantages of the hotel totwit (Limit switch).* Easy installation Easy to use.* No power feed circuit to work.* Reliable work. Precision work.* The price is lower than other types of detection devices.Limit switch with Micro switch.In principle, work may be the same, but with a different section is different in that size with a large Limit switch usage may be used directly to the LOAD at all, but a small Micro switch used for another device, such as a bigger Relay are a matter of LOAD instead.Principle of work -Totwit is usually divided into two normal (NO), and the style is closed (NC), the internal structure of normal position. In front of the touch is not to make the electricity cannot flow through. The working position. When there is an external force, such as the Pistons do move out of press-totwit. Make the change from normal working conditions (NO) normally closed (NC) with the electric current flowing through and when the piston moves back to make-totwit. Back to the original state from the normally closed (NC), normally open (NO) causes the circuit breaker to work.
