Detailed explanation-1: -An actuator is a device that converts energy into some kind of “operation", such as linear movement, rotation, or bending. In addition to electricity, the input energy comes in a variety of forms, such as air (pneumatic) or oil (hydraulic) pressure, magnetic force from electromagnets, steam, and heat.
Detailed explanation-2: -A toggle actuator, for example, features a lever that’s engaged manually. When the lever is pulled, the switch opens or closes (depending on how it’s designed). This manual operation is a simple, effective solution that allows for easy control of an electrical switch.
Detailed explanation-3: -Some may even classify motors as a type of actuator, as they convert energy to move or control some sort of mechanism. Motors are typically used to power industrial equipment that includes the likes of fans, compressors, material handling devices, blowers, pumps and more.
