Limit Switch NC/ NO

A limit switch can be found in devices we use on daily basis, for instance microwave, washing machine and elevator. This control and safety device is designed to detect any kind of physical interaction and send the digital signal to control system. Limit Switch NC/ NO is used in Normally Open (NO) and Normally Closed (NC) circuits. When normally open, the switch will once allow the current to pass. No current will be passed in its resting state. While when the switch is normally closed, the switch will stop the current once and allow the current to flow in its resting state.
