In other words if you are looking for an automated device to work for a certain time period and switch off after the desired time then this timer circuit is the best choice to opt. These circuits can be used for variety of timing purposes in electronic projects like time delay relay etc.

Timer switch circuit diagram. In this project we are using 555 timer ic to create various timer circuit like 1 min timer circuit 5 min timer circuit 10 min timer circuit and 15 min timer. A simple timer circuit can be built by using only a single or two transistors. The figures below show different schematics of simple timer circuits which can be built very easily with few general components. These on off intervals can be adjusted by varying the 555 timer output and number of counter outputs. This on off switch circuit using a 555 timer is simple useful and easy to implement. The on time delay and the off time delay are independently settable and this facility becomes the most important feature of a programmable timer circuit.
Adjustable on off timerusing 555 astable mode in this circuit a timer with cyclic on off operations is designed. Using versatile ic 4060. This circuit uses very basic components like 555 timer and 4017 counter. This timer circuit is designed to switch on a 12 v load in a solar powered installation for a preset period at the press of a button. On off switch circuit using a 555 timer. This circuit has many applications on places where it is necessary to activate and deactivate connect and disconnect an electrical or electronic device.
When the period has expired a latching relay disconnects both the load and the controller circuit from the 12 v supply. Let us discuss in detail about this circuit. In this page we will discuss a very simple yet reasonably useful timer circuit diagram whose on time and off time settings are independently adjustable through.
