Working of Contactors

There are posts on the working of relays, types of relays and so on. To know about them click on the links below. TAKE A LOOK : WORKING OF RELAYS A contactor is also a type of relay. Although they have been explained in earlier posts, their wide use and significance needs to be explained […]


Garage Door Closing Circuit Just using Relays

Because I’m old school, I wanted to build a Garage Door Closing circuit without relying on integrated configurations (555 timer etc) to keep it simplistic. The circuit closes the garage door after two minutes with C3 and four minutes with the addition of C2. The timer relay is surprisingly accurate (+/- five seconds). Another feature […]


Simple Relay Step-Up Circuits

Have you ever needed to power a 12-volt relay in a circuit but only had 6 or 9 volts available? This simple circuit will solve that problem. It allows 12-volt relays to be operated from 6 or 9 volts, or 24-volt relays from 12 volts. While most normal relays require the manufacturer-specified coil voltage to […]


Working of Relays

Working of Relays In this article, the basics of a relay like energized relay and de-energized relay are explained in detail. Also, the design, construction, working, applications, and also relay selection is explained in detail. What is a relay? We know that most of the high end industrial application devices have relays for their effective […]


Types of Relays

Types of Relays In this article, the different types of relays like overload protection relay, solid state relay, solid state contactor relay, Buchholz relay, Mercury Wetted relay and many more are explained with diagrams. . In my earlier post I have alreaady explained the working of relays, and their design and construction. TAKE A LOOK […]

Inexpensive Remote Watering System

This remotely controlled watering system is both inexpensive and easy to expand. It is designed to operate in conjunction with a conventional watering timer and allows remote switching between nine zones. The prototype is used in a bore system, where a deep-well pump must be started and kept running while zones are being changed. This […]
