Navigate through the tab and select, followed by in the diagram pane. Open EdrawMax software and click on File. Alternatively, you can create symbols and add them to your own symbol library. You can import new icons in EdrawMax in a few simple steps. Part 4: How to Create Your Switch Symbol Library There are many other switches you can explore and select according to the task you need it for. Throw: This can be either single or double and shows the number of conducting positions. Pole: The number of contact sets in a switch. A few of the terms you need to be familiar with are given below. This means it has one set of contacts and one switching position. The simplest of the switches has one pole and one throw. There may be numerous close positions in a switch.

A switch is off when it is open and on when it is closed. There are multiple terms used to describe contacts found in switches. However, for high rated electronics, you check for the current rating in the switch. If you want to use the switch for low voltage appliances, the rating will not matter. There may be multiple ratings for AC and DC. Switch contacts have ratings for the current and voltage. The DPDT switch is used anywhere that needs open or closed wiring. It is mostly used to regulate 240V appliances. With a single push, both circuits will turn on or off. This switch has two poles with two similar circuits side by side. For example, to turn a light on or off from 2 different locations. It is usually used in a three-way circuit. One terminal is input with two others as outputs. You can move the yellow control point to change the position of the text. You can double click to edit the text at the symbol. In our electrical software - EdrawMax, you can click the action button then click the Close Circuit menu item to close the circuit switch.

This is the most basic kind of switch with one input and one output.

To make matters simpler, there are three important things to consider in a switch: Switches may be simple devices, but their selection is a whole process depending on what you need it for. Part 2: Factors to Keep in Mind While Selecting A Switch
