This is useful when the triac is used to control outlets, motors, ballasted lights, or other loads where voltage drops or waveform clipping could cause ill effects.

Contactors are used to control electric motors, lighting, heating, capacitor banks, thermal evaporators, and other electrical loads.

Derating of mains powered, phase fired controllers is important as they are often used to control resistive loads, such as heating elements.

Lamp modules are almost silent in operation, and generally rated to control loads ranging from approximately 40 to 500 watts.

In the U.S., these modules are generally rated to control loads up to 15 amperes (1800 watts at 120V).

Often a pressure switch will operate a relay or other control device, but some types can directly control small electric motors or other loads.

A type of relay that can handle the high power required to directly control an electric motor or other loads is called a contactor.

The technique won the Queen's award for technology, while its application for controlling consumer tariffs and loads was approved by the Home Office.

Civilian flying crane helicopter with a gondola under the lengthened nose for controlling slung loads up to 2,000kg (4,400lb).

"It may be more appropriate and feasible to control lesser loads in other places."
