Electrical Timer Diagram. September 6 2015 at 448 pm. A timer switch is a mechanism that controls the on and off timing of electrical equipment such as for appliances and devices.
Timer contacts switch after the set time has expired. R will stay energised until the supply is interrupted if the supply is interrupted then r returns to its original. This further ensures that the timer shuts off completely in case a power failure occurs while the circuit is.
The set time is calculated from when the input turns off.
