Limit switches
Limit switches are switches that are activated by movement or the presence of an object, often as part of a machine. They are crucial in control systems of various machines such as doors, ice cube machines, and car elevators. Limit switches are found everywhere thanks to their suitability for extreme conditions, ease of installation, and reliability.
A limit switch consists of an actuator, housing, built-in switch, and switch housing. Upon detection, the actuator activates the switch, which turns on the electrical network.
Moujen offers a wide range of limit switches in various shapes and sizes, including custom-made ones. Our limit switches are easy to assemble, economical in assembly work and of high quality, certified with UL, CSA, and CE approvals.
With our range, you will always find a suitable limit switch for any industrial or domestic application. Contact us for more information.
What are limit switches?
A limit switch is an electromechanical component used to detect the position or movement of an object. When a machine part or object reaches a certain position, the limit switch activates and transmits an electrical signal. This makes limit switches indispensable in industrial applications, machines, and automation processes.
What exactly is a limit switch?
The question “what is a limit switch?” is often asked by technicians and users looking for reliable position detection. Simply put, a limit switch acts as a sensor that converts mechanical movement into an electrical signal. This allows a machine to automatically stop, start, or change direction, for example.
Types of limit switches
There are different types of limit switches, each suitable for specific applications:
Micro limit switch: compact, highly accurate, and often used in smaller devices or precision work.
Roller limit switch: equipped with a roller mechanism that allows it to respond smoothly to linear or rotary movement.
Spring limit switch: uses a spring mechanism for extra flexibility and durability.
Mechanical limit switch: the classic variant in which physical movement operates a contact point.
In addition, there are limit switches that operate at different voltages, such as a 12V limit switch, 24V limit switch, and 230V limit switch. The choice depends on the application and the electrical installation in which the switch is used.
Limit switch operation
The operation of a limit switch is simple but very effective:
An object or machine part touches the actuator (e.g., a lever, roller, or spring).
This activates the internal switching system.
The limit switch sends an electrical signal to the control system.
This process ensures safety, efficiency, and automatic control in a wide range of machines and production lines.
