Toggle Switch
Introduction of Toggle Switch
The toggle switch is a type of electrical switch that is identified by the presence of handle or lever that makes it possible to control the flow of electric current/signal from a power supply to a device or within a device.
It is a hinged switch that can assume either of two positions ie. ON or OFF. It is used to switch between two conditions in a circuit.
Toggle Switches employ rocker-type contact mechanism.
Being easy in operation, toggle switch can be used in a number of different applications, both in commercial and in house hold appliances.
It is housed in an anti- tracking moulded case for dust free performance, thus last for many years before being replaced.
To protect from false switching, a flip cover is used as switch guard.
Some Toggle switches comes with small length of handle making its operation difficult. Thus, to over come this drawback, Handle extensions are used.
They are available in SPST, SPDT, DPST, DPDT contacts terminology.
Now a days in home applications like for switching lights/fans Rocker Switches are used instead of Toggle Switch.

Classification of Toggle Switch based on application
1. Military Purpose Toggles:
Military purpose toggle switches are designed to meet the requirements of MIL-S-83731. Sealed switches have a silicone rubber lever seal assembled between the lever and the bushing to resist the entrance of contaminants such as dust, sand or water into the contact structure.
2. General Purpose Toggles:
General Purpose Toggles are AC or DC rated mechanically actuated switches designed to respond to many types of mechanical stimulus.
3. Heavy Duty Hesitation Switches:
Heavy Duty Hesitation switches are available in either two or three-position. The three-position switches offer a unique positive center stop/OFF feature with their widespread acceptance for motor reversing and speed control applications.
