The part that causes the contact to be engaged or switched is called the actuator, which basically can be any displacement phenomenon, for example: push, twist, zoom, rotate, light reflection, sound reflection, etc. The structure of a contact switching device symbol consists of […]

This time we will focus on the automatic control based on the ready-made electrical scheme of the sewage pumping station. In the previous lesson, I covered manual control quite thoroughly using the same wiring diagram that we will build on in this lesson. Therefore, I […]

In contact electrical systems, relays, contactors and pushbuttons are used to transfer, amplify, multiply, invert or combine control signals into logic functions. By configuring the contact connections, the appropriate behavior of the control system is achieved. […]

There are many other devices in which the contacts are switched mechanically, inductively, pneumatically or hydraulically. In this lesson, I will provide a summary of contact symbols along with their drives. We know from previous lesson #2 […]

Assume I don’t know what a contactor is. I read the above definition and…I still don’t know. To […]

The principle of operation of relays is simple: driving the relay coil causes the signal to pass on through the contacts. To begin the lesson, we need to understand how relays work, what their features and functions are. Only then can we fully understand […]

We’ll start our schematic reading course with the simplest item we can find in an electrical closet – the cable connector (ZUG). Connectors are a very important element in almost every electrical installation and control and measurement equipment. They provide […]
