kytkennäis
Kytkennäis, also known as a contactor or relay, is an electrically operated switch used for switching electric circuits. It is commonly employed in various applications, including industrial machinery, lighting systems, and automotive electronics, due to its ability to handle high currents and voltages while providing mechanical isolation between the control and power circuits.
Kytkennäis devices function by using an electromagnet to mechanically operate a set of contacts. When an electrical
There are several types of kytkennäis, including general-purpose contactors, motor starters, and specialized relays. General-purpose contactors
Kytkennäis are characterized by their contact configuration, which can be normally open (NO), normally closed (NC),
Maintenance of kytkennäis involves regular inspection for signs of wear, such as pitting or welding of contacts,
