Ohjainkytkin

Ohjainkytkin, also known as a relay switch or a contactor, is an electrical device used to control the flow of electric current in a circuit. It is typically used in applications where a high current or voltage needs to be switched on or off, such as in industrial machinery, power distribution systems, and HVAC systems. The ohjainkytkin consists of a set of contacts that open and close to interrupt or complete the circuit, and a mechanism to operate these contacts. The mechanism can be manually operated, such as a pushbutton or lever, or it can be controlled by an electrical signal, such as a relay or a control circuit. Ohjainkytkin are designed to handle high currents and voltages, and they are often used in conjunction with other electrical components, such as fuses or circuit breakers, to provide additional protection and control. They are available in a variety of sizes and configurations to suit different applications, and they are an essential component in many electrical systems.
