5. Introduction
Feasibility study and analysis of the ability
 to complete a project successfully
 taking into account legal
 economic
 technological
 scheduling
 and other factors

6. Background
 The first electric switch employing
"quick-break technology" was
invented by John Henry Holmes in 1884
in the Shieldfield district of Newcastle
upon Tyne.
 The world today using toggle
electric switch was invented in 1917 by
William J. Newton. 6

7. Definition
In electrical engineering, a switch is
an electrical component that can break
an electrical circuit, interrupting the
current or diverting it from one conductor
to another.

8. Types of Electric Switches
 Level Switches
 Rocker Switches
 Limit Switches
 Membrane Switches
 Pressure Switches
 Pushbutton Switches
 Rotary Switches
 Spiral & stick

9. Types of Electric Switches
 Slide switch: A slide switch has a knob that you can
slide back and forth to open or close the contacts.
 Toggle switch: A toggle switch has a lever that you
flip up or down to open or close the contacts.
Common household light switches are examples of
toggle switches.
 Rotary switch: A rotary switch has a knob that you
turn to open and close the contacts. The switch in the
base of many tabletop lamps is an example of a
rotary switch.

10. Types of Electric Switches
 Rocker switch: A rocker switch has a seesaw action. You
press one side of the switch down to close the contacts, and
press the other side down to open the contacts.
 Knife switch: A knife switch is the kind of switch Igor
throws in a Frankenstein movie to reanimate the creature. In
a knife switch, the contacts are exposed for everyone to see.
 Pushbutton switch: A pushbutton switch is a switch that has
a knob that you push to open or close the contacts. In some
pushbutton switches, you push the switch once to open the
contacts and then push again to close the contacts.

11. Methodology
 The basis of low ampere and high ampere Electric Switches
are manufactures.
 like 5A- 20A switch.
 Due to the respect of time Electric Switches manufacturing
technology has changed.
11

12. Advantages
 Suitable for switching higher power loads than other sensor technologies (5 A at 24V
DC or 10A at 120V AC typical vs. less than 1 A for proximities or photoelectrics)
 Immunity to electrical noise interference
 Immunity to radio frequency interference (walkie-talkies)
 No leakage current
 Minimal voltage drops
 Simple normally open and/or normally closed operation
12

13. Disadvantages
 May occasionally respond to false signals.
 Usually costs more than a manual model.
 Needs more maintenance than a manual model.

27. Sources
 All raw material suppliers found
in China.
 Low demand accessory are
found in local electrical
company.
27

28. Mode of transportation
 Truck transportation
 Train transportation
 Sea-port using

29. Process Technology
 Outline of process technology
 Availability and proneness
 Comparative technology
 Level of technology
 Availability of manpower

30. Utility
 Typically use about 25%- 45% less
energy than traditional
incandescent, saving you money.
 Can last 10-45 times longer.
 About $10 and could save you as
much as $30 a year.
30

31. Location
 Proximity to market
 Availability of raw material
 Availability of utility
 Availability of skilled technical
manpower
31

32. Location
 The location of our
project can be in the area
of Gorai, Mirzapur,
Tangail.
32

33. Proximity to market
 Gazipur is about the center of Bangladesh and
very close to Dhaka.
 In Bangladesh the main local markets are in
Dhaka, Chittagong and Bogra.
 It is very easy to cover the local markets.
33

34. Availability of raw material
 In main raw materials are not available in
our country.
 This place is close to the airport and easy
road transport system.
 It is very easy to collect raw materials.
 So we have to depend on other
developed country.
34

35. Availability of utility
 To run this plant we need much more transport, electricity.
 It is very good area to have the proper utilities.
 Because There are lots of electricity generation plant in
Savar and Gazipur area.
 In this area has two river so we can easily collect water if we
need.
 So we can say that this place are sweet able to run our
Project.
35

36.  Manpower are available but Skilled technical
manpower is not available.
 Have to trained few engineers from abroad.
 Extra cost for the project but give us more benefit in
future.
