A transistor switch is a circuit in which the collector of the transistor is switched ON/OFF with relatively larger current in response to a correspondingly switching low current ON/OFF signal at its base emitter. As an example, the following BJT configuration can be used as a switch for inverting an input signal for a computer logic circuit A Transistor switch, which is used for opening or closing of a circuit, that means the transistor is commonly used as a switch in the electronic devices only for the low voltage applications because of its low power consumption. Transistor work as a switch when it is in cutoff and saturation regions. Types of BJT Transistors When you switch an NPN transistor you put current thru the VBE junction and it gives collector gain. Turning it off empties the VBE junction from whatever charge remains and stop the collector flow In small, discrete quantities, transistors can be used to create simple electronic switches, digital logic, and signal amplifying circuits. In quantities of thousands, millions, and even billions, transistors are interconnected and embedded into tiny chips to create computer memories, microprocessors, and other complex ICs

The transistor switch operating areas are referred to as the Saturation Region and the Cut-off Area. This means we can then disregard the operating Q-point biasing and voltage divider circuits needed for amplification and use the transistor as a switch by driving it back and forth between its full-OFF (cut-off) and full-ON (saturation) regions as shown below One of the most common uses for transistors in an electronic circuit is as simple switches. In short, a transistor conducts current across the collector-emitter path only when a voltage is applied to the base. When no base voltage is present, the switch is off.
