Different types of 
electrical switches 
and their uses
Electric switches are electromechanical gadgets that 
are utilized in electrical circuits to control electricity, 
sign controllers of the whereabouts of machine parts 
and workpieces, control gadgets manually, manage 
the lighting, and so on. Electrical switches come in 
loads of styles and can be operated by hand, foot, 
level, or objects. Switches can be simply on-off types 
or can have multiple designs and positions that, for 
instance, can manipulate the rate of a multi-speed fan. 
Switch operators can be in diverse shapes and sizes, 
like, toggles or buttons, and come in various colors.
There are many types of electrical switches 
Types of such as foot-switch, pushbutton, LED dimmer switch. As mentioned above they 
come in different shapes, sizes, colors. Not only 
Electrica that but different switches have different purposes.

Foot Switches
• Foot Switches are electro-mechanical devices used to manipulate electricity in an electrical circuit by 
means of foot strain. They are frequently used on machines in which an operator needs his or her 
hand to stabilize a workpiece. Its key specifications include the number of pedals, switching feature, 
voltage score, and current rating. Footswitches are used in lots of press applications in which hand 
controls can’t be used to actuate a cycle. They also are normally used in medical equipment and 
office machines.
Level Switches
Level Switches are electro-mechanical gadgets used to detect the extent of liquids, powders, or solids. 
They are mounted in tanks, hoppers, or bins, and can give output to a control system. In a few 
instances, they may be used to actuate a tool directly, along with level switches used in residential 
pumps. Key specifications consist of measured media, output type, switch type, voltage, and current 
scores. Level switches are used drastically in the technique industries to observe tank and hopper 
levels. They are used in normal appliances also.
Limit Switches
Limit Switches are electro-mechanical gadgets designed to sense motion and position routinely and 
offer output alerts to a controller. They are accessible as bare switches, or in rugged enclosures meant 
for the tough environment. Key specifications encompass actuator type, voltage, and current score. A 
type of actuator sorts from rods to whiskers guarantees that any component or workpieces can be 
sensed with the help of a limit switch. Limit switches are used in lots of common customer machines 
which includes washing machines. In their ruggedized shape, they may be used in many types of 
manufacturing centers inclusive of steel turbines and paper plants.
Magnetic Switches
Magnetic Switches, also called reed switches, are a form of an electric switch in which the 
switch closure mechanism is operated through the presence or absence of a magnetic 
field. In a regular design, the switch contacts are usually open while a magnetic field isn’t 
in close proximity to the switch. One application for magnetic switches is to control the 
opening and closing of doorways and windows as part of a safety system.
LED dimmer switch
A LED Dimmer Switch is used to manipulate or alternate the speed of a fan or once in a 
while to exchange the depth of light among bright and dim. Earlier, the regulators used to 
rotate in steps, each step represented a particular level of fan speed, but the LED Dimmer 
switch regulator lets you rotate it smoothly without any steps or levels.
Pressure Switches
Pressure Switches are electro-mechanical gadgets used to feel fluid stress and provide output 
indicators to a controller. They frequently use a diaphragm because of the sensing means. Key 
specifications encompass the stress type, media measured, the material of diaphragm, connection of 
the pressure, minimum and maximum operating pressures, and switch current. Pressure switches are 
used to keep the pressure under the limits in the lubrication system wherein over-pressure or below-
pressure conditions can bring about harm to the machine or equipment.
Pull Chain Switches
Pull Chain Switches are electro-mechanical appliances that are hand-operated and used 
to turn a circuit on and off. Their most usual utility is in lighting fixtures in which they may 
be used to turn lamps on or off. Pull Rope Switches are used as emergency prevent 
devices like in trains. Key specifications include switching characteristics, voltage, and 
current scores, and also numerous functions particular to e-stop applications such as 
detection of the broken-cable.
