Every leading country is continuously looking out for novel ways to accelerate the growth and development of its industries. Several professional experts, scientists, and researchers are investing a considerable amount of time in formulating new ideas and technologies that fetch more revenue and help meet the demands of a consumer-centric society. However, it is essential to provide a significant amount of capital for the expansion of the electrical industry as it fuels every business and organization that is running in the country.
In this article, we will be focusing on the definition, mechanics, uses, and benefits of an integral electromagnetic device called a limit switch. We understand that for a person who has close to no knowledge in the technical or mechanical field, it is if difficult to comprehend how certain electrical tools and appliances function. So, let us start with the most basic question—what is a limit switch, and why is it important for the electrical industry.
Definition and Applications of a Limit Switch
In simple terms, a limit switch is a small tool or switch that is primarily used to detect blockages within machines and controllers. In other words, if there is an object that might disrupt the functioning of the machine, a limit switch spots it and indicates to the user about it in a timely manner. Now, below we have carefully curated a list of applications that deploy a limit switch:
- Garage doors
- Control cabinets
- Textile machinery
- Vehicles and life trucks
- Process equipment and packaging machinery
- Machine tools like transfer lines, presses, and special machinery
- Material handling equipment like elevators, hoists, cranes, conveyors, etc.
Since you are now familiar with all the applications, lets us understand some of the many core functions of a limit switch. Every electrical tool, equipment, and the appliance is carefully designed by a team of experts so that it contributes to the smooth function of the overall process.
Similarly, a limit switch is used for accurate detection of speed, range movement, travel limit, positioning, absence and presence of an object, and sudden breaking of current whenever hazardous conditions arise. In addition, every limit switch is an integration of multiple parts like actuators, terminals, and switch body. Below are some of the many types of limit switches:
- Adjustment roller lever
- Roller lever
- Roller plunger
- Rounded plunger
- Cable pull
- Flexible roll
- Rotative axis
How Does a Limit Switch Work?
Whenever a target or an object comes in contact with an actuator, the plunger’s movement automatically results in the electrical contact within the button or switch to partially or completely open the given electrical connection.
However, similar devices like capacitive proximity sensors, photoelectric sensors or inductive sensors can achieve the exact same result without getting in contact with the object. On the other hand, almost all types of limit switches are mechanical in operation and have contacts that are capable of switching higher levels of current in comparison with proximity sensors.
Find Your Way Forward by Joining Hands with a Leading Service Provider
Even though most limit switches are simple to operate and easy to install, it is a good idea to find some time out for research and get in touch with a reliable and prestigious service provider in the electrical field. They usually come with a team of professionally trained technicians who carry all the right knowledge about all the electrical tools and types of machinery.
Additionally, we recommend you surf online and look for some top-notch online electrical stores that carry an expansive range of limit switches and other electrical products. This will help you save both times as well as money.
