Introduction to :

Safety switches

Switches are defined as electrical components that can

break an electrical circuit, interrupting the current or diverting

electrical current from one conductor to another. Switches

can be operated by human operators who manually control

electric circuits, computer aided software.There are many

different types of valves that are found in different industries

and applications are as Below:

Switches Safety switches

Push-button switches Rotary switches

Foot-switches Joysticks

Rocker switches Waterproof switches

Control foot switches Toggle swiches

P u s h - b u t t o n s w i t c h e s

Push button switches are also known as biased

switches. They are switches that only work when

specific buttons assigned to them are pressed

hence withdrawing pressure breaks the circuit.

They are considered the most used in electric

circuits and electrical designs.

Push button switches mostly comprise of internal

spring tools or knobs that aid in opening or

closing circuits when pressed.

F o o t s w i t c h e s

Foot switches. These types of switches are

operated by applying foot pressure to either

open or close circuits.

Foot switch applications usually require specific

electrical ratings, cables, pedal actions and

other variations.

Consumers are advised to consider factors like

proper current and voltage rating, enclosure

rating, the size and shape and finally singe or

multiple pedal before purchasing foot switches.

R o c k e r s w i t c h e s

Rocker switches can be defined as on/off

switches that rocks when pressed meaning

that when one side is pressed the other

remains raised and when the raised side is

pressed down the other one is raised up.

Rocker switches are operated by pressing

one side of the switch up or down to either

close or open the circuit respectively. They

are normally used to directly power electrical

devices and can be found in a wide range of

electrical appliances or devices.

C o n t r o l - f o o t s w i t c h e s

This are switches that are mainly open or closed

via various feet movements. They are mainly

designed to be fitted in lower places so that legs

remain to be the only limbs that are fit to control

them.

They are fitted mainly in vehicles' brake pads and

acceleration pads. These types of switches are

similar to foot switches in various ways the main

one being the fact that they both use the same

part of the body.

S a f e t y s w i t c h e s

Safety switches are switches installed to protect

equipment and people from damage or electrical

shocks.

They usually monitor the flow of electricity hence

are able to detect any malfunction that can

cause harm or damage.

R o t a r y s w i t c h e s

These are types of switches mainly activated by

rotating knobs hence reaching the correct

positions ensuring the completion of a circuit.

Operate with a twisting motion of the operating

handle with at least two positions.

Rotary switches can have different positions

hence permitting a particular point to be

connected to one of a number of other points in

the electronic circuits.

J o y s t i c k s

Joystick switches-these are types of switches

triggered by levels that are able to move in more

than one direction.

Joystick switches work on the principle of on

which way the lever is pressed and by how far it is

pressed.

Car gear box is one of the electrical applications

that use this type of switches. Electrical

equipments that are involved in controlling

including camera jeeps and cranes use this

technology.

Wa t e r p r o o f s w i t c h e s

Waterproof switches - these types of switches

are designed to prevent the entry of water, water

if in contact with electricity is likely to cause

electrocution of aqua life and human beings.

Waterproof switches are used in water based

electrical installations or equipments that have a

high risk of getting into contact with water and

cause mechanical and electrical failures.

Waterproof switches can be used inside water or

aqua situations without fear of electric

malfunction.

To g g l e s w i t c h e s

Toggle switches are mainly operated by levers that

one flips up or down to open or close the contacts.

Toggle switches are mainly triggered by devices in

one or two more positions.

Household electrical wiring connections are a

good example of how these switches work.

These switches have inbuilt springs that are held

tightly in the positions they are switched to.
