According to a research report "Relay Market by Type (Electromechanical, Thermal, Reed, Time, PhotoMOSFET, Solid State, MEMS), Application, Voltage Range (Low, Medium, High), Mounting Type (Panel, PCB, DIN Rail, Plug-In) and Region - Global Forecast to 2030" published by MarketsandMarkets, the relay market size is estimated to be USD 9.0 billion by 2022 and is projected to reach USD 14.7 billion by 2030, at a CAGR of 6.3%. A relay is an electronic control device that has a control system (also called an input loop) and a controlled system (also called an output loop) and is usually used in automatic control circuits. It is an "automatic switch" that uses a smaller current to control a larger current. Relay plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.
