Which two components are controlled by electromechanical sensors

An electromechanical component is one that uses an electrical signal to cause some kind of mechanical change, such as motor turning. These normally use an electrical current to create a magnetic field which causes a physical movement. All types of relays and switches are available in this category.

Examples of common electromechanical devices household appliances such as dishwashers, refrigerators or vacuum cleaners. transportation, such as trains and trams. the automobile industry, with alternators and electric motors. CD and DVD players, printers.

Electro-Mechanical (Relay) Control Electro-mechanical Control is also referred to simply as "Relay Control" perhaps a more accurate term, since solid state Relays, Timers, and Counters have become very common. Today this approach is common with very simple and small applications.

Three common types are parallel (two-fingered), three-fingered, and angled designs. The most common are parallel designs, with two fingers that close on a workpiece to grip it, or open out to create contact friction on an inside surface.
