Snap action mechanism is used to overcome a large resistance of a member with a small driving force. This mechanism works by converting a small amount of motion or force into a large amount of motion or force. It is used in various applications such as switches, valves, and clutches.

Working Principle:
The snap action mechanism works on the principle of leverage. The mechanism consists of a lever that is connected to a spring. The lever is designed in such a way that it can store energy when it is moved from its initial position. When the lever is released, the stored energy is converted into a large amount of motion or force.

Applications:
1. Switches: Snap action switches are commonly used in electronic devices such as keyboards and remote controls. These switches provide a tactile feedback when pressed, which makes them ideal for applications where the user needs to know when the switch has been activated.

2. Valves: Snap action valves are used in applications where a small amount of force needs to be converted into a large amount of force. These valves are commonly used in hydraulic systems and pneumatic systems.

3. Clutches: Snap action clutches are used in applications where a small amount of torque needs to be converted into a large amount of torque. These clutches are commonly used in automotive and industrial applications.

Advantages:
1. Snap action mechanisms are simple and easy to use.
2. They provide a high level of accuracy and precision.
3. They are reliable and durable.

Disadvantages:
1. Snap action mechanisms can be expensive to manufacture.
2. They can be difficult to repair if they fail.
3. They may require a high level of maintenance to keep them operating smoothly.
