Frequently Asked Questions (FAQs)
1. What do limit switches do?
A limit switch is an electromechanical device operated by a physical force applied to it by an object. Limit switches are used to detect the presence or absence of an object. These switches were originally used to define the limit of travel of an object, and as a result, they were named Limit Switch.
2. What is meant by limit switch?
Definition of limit switch : a switch that operates as an automatic control to prevent a mechanism or process from going beyond a prescribed limit.
3. What is an example of a limit switch?
A good example of this is an automatic garage door. Without a limit switch that stops the door when it reaches the bottom rail, the door would keep moving downwards and eventually crash into the ground, causing serious damage. Limit switches can also be used as part of a larger control system.
4. How are limit switches activated?
In most cases, a limit switch begins operating when a moving machine or a moving component of a machine makes contact with an actuator or operating lever that activates the switch. The limit switch then regulates the electrical circuit that controls the machine and its moving parts.
5. Is a limit switch open or closed?
A limit switch may be normally open (NO) or normally closed (NC) in its normal resting position. A NO device, when actuated, switches to close (or "make") the circuit, whereas an NC switch would open and break the circuit when actuated.
