A switch in an electronic device is used to interrupt the flow of electricity or electric current. Electrical switches are binary devices, they can be either completely off or completely on. In simple English, a switch is an electronic device that is used to break or make the electronic circuit.
3. WHAT IS AN ELECTRICAL SWITCH?
A switch in an electronic device
is used to interrupt the flow
of electricity or electric current.Â
Electrical switches are binary
devices, they can be either
completely off or completely
on.
7. Role of switch in the Circuit
In a series circuit, devices are strung together
one after another so that whatever current flows
through one must flow through the other, each
in turn.
If the switch is open, no current will flow at all.
The switch could be placed anywhere in
the circuit and it would have the same effect.

Switches increase available network
bandwidth
Switches reduce the workload on individual
computers
Switches increase network performance
Networks that include switches experience
fewer frame collisions because switches
create collision domains for each connection
(a process called micro segmentation)
Switches connect directly to workstations.

They are more expensive compare to network
bridges.
Network connectivity issues are difficult to be
traced through the network switch.Broadcast
traffic may be troublesome.
If switches are in promiscuous mode, they are
vulnerable to security attacks e.g. spoofing IP
address or capturing of ethernet frames.
Proper design and configuration is needed in
order to handle multicast packets.While limiting
broadcasts, they are not as good as routers.
