Modifying the view of a Relay

Let’s begin with a simple component, the Relay. In this example, the shape and the orientation of the component are modified. A basic relay contains a coil and an SPDT switch. Now, the position of the coil and the switch are modified in this example. The expected view is shown below and the below procedure explains how to transform from the actual view to the expected view.

Step1: Select the component from the pick devices tab.


Step2: Place the component on the worksheet. Right-Click the component and then select the ‘Decompose’ option from the Right-Click Menu.


Now, the individual segments or parts of the component get decomposed. So, these parts are now movable or editable. Select the individual parts and drag them to get the expected view.

Step3: Select all the parts of the expected view. Right-click the selected part and then select the ‘Make device’ option from the Right-click Menu.


Step4: Through a series of options the name of the component, Index, and other reference parameters can be edited or left unchanged. After this step, the component is created in the library and can be used as a regular component by placing it in the workspace. The decomposed component can be deleted.

Now, let’s verify whether the modified component works similarly to the default component or not. Below is the simulation video that compares the operation of modified and default components. The procedure to modify the component is also shown.

One of the most common styles of switches is the SPDT Mechanical switch. The SPDT stands for Single Pole, Double Throw. Simply stated, there is a common terminal on the switch where the voltage and current is applied, and that voltage and current can be either directed to the normally open or normally closed terminal. The direction of the current flow is typically directed by a mechanical roller lever that actuates the switch.
