The main role of limit switches is to cut off the power to machinery when it reaches the extent of movement that is safe. An example of this is if an elevator went too high or too low for safety measures, the power would be cut off because of the limit switch.
LAN stands for Local Area Network. LAN switches work when switches are configured to limit broadcast levels. LAN switches are produced by the company Cisco.
Auxiliary switches are separate switches with circuit which helps for the function of commutation of main switches of a converter.
Limit switch is one type Of " Contact Sensor" , In that there is Normally Open Contact & Normally Close Contact, In limit switch there is Plunger it is Directly Connected to NO & NC Contact if we press the plunger NO contact become NC & NC contact become NO, Working Principle same as Contactor ( DOL starter ) main difference is in contactor There is Coil to attract the Plunger But In Limit Swict Plunger is Operated Mecanically.Limit Switches is used mainly for Safety Purpose & to take Feed back for PLC in Automation industries........Source(s):In My Plant I have installed limit Switches.. A limit switch is a switch, usually mechanical, that is actuated by a moving part of some machine. Its operation is much like any other switch in that there are contacts that move when a plunger or lever on the outside of the switch is pushed. Internally there is an over center spring mechanism that snaps the switch open or shut in response to a gradual motion of the plunger or lever.Many limit switches have three terminals. One is the normally closed contact, another the normally open contact, and the third is the common that switches between these two as the mechanism is moved.
aUTOTECH IS A COMPANY THAT MAKES ELECTRONIC LIMIT SWITCHES AND ROTARY RESOLVERS. tHEY ARE USED IN INDUSTRIAL PLANTS
Main switches typically lift up to turn on because this motion is more intuitive and easier to identify as an "on" position. Other switches may be designed to move downward to differentiate them from main switches and provide a clear distinction between different functions or circuits.
The role of ethernet switches in a network is to allow computers and other devices to talk to each other. This also allows many users to access a shared device such as a printer.

There are two limit switches per axis. Each switch is located at both extremities and they prevent the axis to go beyond the limits.

The main difference is that air break switches lack a mechanism for suppression and load break switches do have them. They are both disconnect switches but have different uses.
There are three main types of sump pump float switches available for purchase: vertical float switches, tethered float switches, and electronic float switches. Each type operates differently to activate the sump pump when water levels rise.
An SPST switch can break the connection or hold the connection depending on which switch your using.
