Switches The are many types of switches but in this section we'll just go into mechanical switches. Switches allow or stop the flow of current or control which path it is to take. The simplest swi

Drawing Circuits When designing circuits it is not practical to draw physical likenesses of the components you wish to use. In place of each component a symbol is use to represent it. For example:

Thyristors Thyristors have a similar function to Unijunctions they act as switches. Thyrstors use current flow as a switch. There are two types of thyristors. Silicon-Controlled Rectifi

Unijunction Transistor The unijunction transistor (UJT) works like a switch. It doesn't amplify the voltage, it just lets current through or not depending on the in input voltage. Irrespective

RelaysRelays are basically switches that are controlled by electricity rather than mechanical input. Inside the relay, the current used to alter the state of the switch is put into a coil. As we now f
