42 on off timer circuit diagram

This ON-OFF Switch circuit uses the well known 555 timer. The timer activates a relay through a bipolar transistor in order to connect or disconnect the device we want to control. Manual activation is performed through two momentary contact switches. Switch 1 (SW1) is used to enable and Switch 2 (SW2) is used to disable the device. 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. Using Versatile IC 4060.

The contact of the relay finally drives any external AC load. A Push On Push off latching switch can use to ON and OFF the load alternatively with the same push action. Push on push off switch using 4017. This circuit is using a decade counter IC 4017, which counts or shifts the output for each rising edge of applied clock signal.The IC has 10 outputs, here only two outputs are used to switch ON and OFF by shifting the HIGH state between these two outputs.

Simple Delay Timer Circuits Explained. In this post we discuss the making of simple delay timers using very ordinary components like transistors, capacitors and diodes. All these circuits will produce delay ON or delay OFF time intervals at the output for a predetermined period, from a few seconds to many minutes. The ICS KD series repeat cycle timer produces an output which alternates between energized and deenergized states at a repetitive rate. The first cycle begins when input voltage is applied to the timer. During this period the output is deenergized. At the end of this off time, the output energizes and the on time begins.
