7. A REVIEW ON AN EXAMINATION AND TESTING SWITCH USING DOOR SWITCH TESTING KIT

The paper is about testing Refrigerator door switch. The project is Based Relay logic circuit (RLC). It is automatic machine which indicates user if any switch is not working. Each switch is attached to a lamp that will emit white light to be tested and r emarked in series. T he broken switch incorporates timers, so the user can change the pace of operation to suit th eir needs. For many different reasons, test switches have historically been implemented in ac a nd dc circuits of protection, metering, and control (PCM) systems. This essay examines test switches' functions. and examines them in light of the characteristics of relay logic technology that is used in RLC systems today. Testing requirements changed have as a result of co ntinuous self-testing functions in modern LEDs.
