Signal indicator light, a device that uses light to monitor the working or position status of circuits and electrical equipment. It is also the most intuitive and unique monitoring component in automation equipment. The main function is usually used to reflect the working state of the circuit (with or without electricity), the working state of electrical equipment (running, outage or test) and position state (closed or disconnected), etc. To remind the operator to deal with the fault in time, or operate a certain function to complete the relevant action.
Push button switch, also known as control button (referred to as button), is a low-voltage electrical appliance that can be manually reset and generally automatically reset. Buttons are usually used in circuits to issue start or stop commands to control the on and off of electric coil currents such as electromagnetic starters, contactors, and relays.
Main functions: generally used in control circuits with AC and DC voltages below 440V and currents less than 5A, generally do not directly manipulate the main circuit, but can also be used in interconnected circuits. In order to control the operation of the equipment, stop, pause or reset and other functions.
