Some types of Switches are more common in Laptop motherboards

Let's first start by reviewing the basics

1. Turn-ON switch Technique Self-explanatory

2. Turn-ON control NPN (Bipolar) transistor and N-Channel

(MOSFET) switch transistor is done by INCREASING voltage on

relative Base or Gate ) To Emitter or Source (Source) respectively.

Turn-OFF is the opposite. Bipolar and MOSFETs are related to the

silicon manufacturing process used. 3. Turn-ON control of PNP

(Bipolar) and P-Channel (MOSFET) electronic switches is done by

DECREASE the Voltage on Base or Gate relative to Emitter or

Source respectively. Turn-OFF works the other way. Basic Switch

(Function, Operation, And Design Properties) • An electrical switch

used to connect or disconnect two points from a system so as to

achieve a goal or make something happen or not happen. Being

more specific, the purpose of the switch is to control the electrical

current. • Minimizes ON-switch resistance, when the switch is

CLOSED. • Another important feature of an efficient switch is to

show very high resistance to current flows when OPEN (OFF) and

can accommodate large voltages across switches without breaking

down. Ideal Switch • An ideal switch is capable of switching an

infinite number, Shows zero resistance to current flow when

CLOSED (ON) and unlimited resistance are present when OPEN

(OFF) and can accommodate (or stand-off) an infinite voltage. •

Because the ideal switch is impractical, the parametric switches are

designed and listed on the data sheet for the performance reports

of integrated spi flash integrated switches and io controlling chips

and are integrated among each other.
