About micro switches

These are small snap-action switches which can be switched on or off using the small act of force. These switches are made of metal strip which is stiff in make and has a spring attached to it. When the force is applied on the switch button, the strip flips. Now, as soon as the force starts receding away, the switch flips back. A typical switch will be of the dimension 3mm x 3mm x 9mm. Flipping of the switch makes light clicking noise.
