Micro Switches also known as snap-action switches. These are small, sensitive electrical switches that require minimal physical force to operate.
Function:
Micro switches use a spring-loaded lever to quickly open or close electrical circuits. 
Mechanism:
They work through a tipping-point or "over-center" mechanism, providing a rapid change in contact state. 
Applications:
Household appliances (microwave, refrigerator door latches). 
Automotive industry (brake pedals, door locks). 
Industrial equipment (limit sensing, safety mechanisms). 
Types:
Available in various types such as subminiature, standard, and heavy-duty, with different actuators and terminals. 
Features:
They are known for their reliability, long lifespan (up to millions of cycles), and the distinct "click" sound when activated. 
Components:
They consist of an actuator, switch mechanism and contacts. 
Terminals:
Micro switches have terminals labeled common (C), normally open (NO) and normally closed (NC).
