What is a Prekldača?


A prekldača, often referred to as a switch. is a fundamental electrical device used for controlling the flow of electricity. It serves as a mechanism to turn electrical circuits on and off.

Note : For Brevity we have denoted prekldača to PKD


Prekldača plays a crucial role in various electrical systems. nsuring efficient energy usage and safety.


There are several types of prekldača available Including toggle switches Rocker switches. Push-button switches and rotary switches Each designed for specific applications.

How Does a Prekldača Work?

Basic Principle

At its core, a prekldača operates on the principle of interrupting. or completing an electrical circuit. When the switch is turned on, it allows electricity to flow through the circui. And when turned off, it interrupts the flow.


The primary components of a prekldača include the contacts, actuator, and terminals. These components work together to control the flow of electricity.


Depending on its design and configuration, a prekldača can perform various functions. Such as controlling lights, appliances and machinery.
