Electronic Timers are widely used in many gadgets and have limitless application in our daily life. You might have come across several timer electronic circuits which is capable of producing short time delay. The above shown electronic design capable of producing delay up to 24 hours so that it can be employed in numerous ways such as alarms, device activators etc. This diagram demonstrates how to build a 24 hours timer circuit it around an IC 4060. Let us move into working explanation of this circuit.

IC 4060:

IC 4060 is a formidable integrated circuit especially used for timing and oscillation purpose. It consists of ten active high outputs that can produce desired time delay from few seconds to hours. IC 4060 is a oscillator binary counter cum frequency divider. This Integrated circuit also has a inbuilt oscillator which is purely based on three inverters. The frequency of the internal oscillator is determined by the value of resistors and capacitors connected with...

A very basic question. I've just bought a digital time switch model TC 24.21 from Muller. According to the back of the timer it takes 230V~50-60Hz, and I'm a bit stuck exactly how and what to connect the timer up to to get it working.

All I'm trying to do at the moment is connect up the timer so the front turns on. I'll worry about the relay wiring once I've gotten that sorted.

Here is a picture of the back.

And the front:

I presume I need to connect the L (live?) terminal to the positive terminal of the power source and the N (neutral?) terminal to the negative terminal of the power source, but I'm stuck with what power source to use? I can't safely plug it into mains power?

Datasheet is...
