A lever ( or US: ) is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum. A lever is a rigid body capable of rotating on a point on itself.

In electrical engineering, a switch is an electrical component that can disconnect or connect the conducting path in an electrical circuit, interrupting the electric current or diverting it from one conductor to another. The most common type of switch is an electromechanical device consisting of one or more sets of movable electrical contacts connected to external circuits.

While levers are primarily mechanical, they can indirectly control electrical systems via mechanical relays or actuators.

No, switches can also adjust settings, control volumes, or change operational modes in electronic devices.

Yes, switches can control mechanical systems if they are part of an electrical control circuit or system.

A fulcrum is the pivot point around which a lever rotates to exert force or control.

A pressure switch activates or deactivates based on the pressure level it detects, commonly used in systems like air compressors.

Yes, there are three classes of levers, classified based on the relative positions of the fulcrum, load, and effort.

A dimmer switch allows for the adjustment of light intensity, whereas a regular switch typically only offers on/off control.

Many machines utilize levers for control and operation, but not every machine requires a lever for its function.

Efficiency depends on the application. Levers are effective for mechanical advantage and control, while switches are efficient for controlling electrical flow.

Absolutely, switches are often used in safety devices to ensure electrical systems are safely turned off or on under specific conditions.
