Microswitches have two main areas of application:
Firstly they are used when a low operating force with a clearly defined action is needed.
Secondly they are used when long-term reliability is needed. This is a result of the internal mechanism and the independence of the closing force on the switch contacts from the operating force. Switch reliability is largely a question of the contact force: a force which is reliably adequate, but never excessive, encourages long life.
Micro switches are very widely used; among their applications are appliances, smart doorlock,machinery, industrial controls, vehicles, and many other places for control of electrical circuits
