A micro switch is a generic term used to refer to an
electric switch that is able to be actuated by very little
physical force, through the use of a tipping-point
mechanism.

Answer / murthy

Micro switch is a switch which change the mechanical contacts from one position to another position NO (normally open)to NC (normally close) when the corresponding parameter reaches to set parameter...

power ratings depends upon the material& thickness used for mechanical contacts

Answer / haridass

Micro switch, the name itself says that the switch which
can be operated in the micro movements like
pressure/level/temp sensors fine expansions. It returns
back with the spring operation by switching the potential
free contacts from NO-close & NC-open.

Answer / rahul nayak

Micro switch is just like our ordinary switch but the
difference is that it regains its original position i.e.
normally close contact upon removal of force to it. it has a
spring lever mechanism. & two contacts nc & no. its used for
safety purpose to limiting the movement of some movable
parts & to take a feedback also.many applications are there
in which we can used it.

Answer / nandu

Micro switch
in the name itself it
defined as the switch
which operates micro
level voltages or
currents such that on/
off conditions uses in
small scale
measurment of IC's
and digital applications

Answer / sunil

micro switch is used with the level switch for the
measurment of derator level in power plant

Answer / vivek majji

Micro switch is a switch which change the contacts if the
mechanical input is given. there is no need of external
power supply.

Hi friends, from Aug 4th onwards iam getting spikes for analog inputs in our DCS for a period of 800ms. I throughly checked every thing, finally i found that the DI, DO's from MCC panels shields are terminated in the Signal Earth where Analog Input signals shields are terminated. Is there any problem with this type of termination?. i checked the induction voltage from MCC and getting around 25VAC, please suggest me in this concern. Our plant is 8months old only. DCS is Siemens Make Simatic PCS7, and the transmitters are Yokogawa make.
