Timer type describes the timer function or mode of operation of the NC time delay relay. Mechanical relays create a Clicking sound that indicates movement o the COMMON terminal. The NC contact of a limit switch, when used in a circuit breaks the circuit or current flow when its actuator is pressed. Remains closed until a certain condition is satisfied. 403-869. AgCdO contact material. A limit switch consists of at least one NO contact in it. For the OFF-delay, the timer does not start when the voltage is applied. 1NO-1NC TIMED CONTACT CONFIGURATION.
