1. What is mini limit switch?
A mini limit switch is a 3-terminal, momentary action switch with 1 Normally Open (NO) and 1 Normally Closed (NC) contact. It features a silver-tone lever hinge for easy control. This switch is designed for precise control and automation in various applications, including appliances, electronic equipment, automatic machines, and automotive electric systems. Crafted with precision, it ensures high quality and durability, making it suitable for DIY projects. The switch is easy to install and is suitable for users of all skill levels.
2. What is the purpose of a limit switch?
The purpose of a limit switch is to detect the presence or absence of an object, as well as to limit the movement of a mechanical component by triggering an electrical signal when the object reaches a specific position. These switches are commonly used in industrial and automation applications to control machinery, set boundaries for moving parts, and ensure safety by halting or altering the operation of equipment based on the position of an object or the movement of a machine. Limit switches play a crucial role in providing feedback and control in various systems, enhancing precision and safety.
3. How are limit switches activated?
Limit switches activate through physical contact or mechanical movement. Two main types include:
Mechanical Actuation:
- Push-Button: Physically pressed by contact with an object or moving part.
- Plunger: Electrical contact made or broken using a plunger.
- Roller Lever: Activated when a roller lever touches an object or surface.
Non-Contact Actuation:
- Magnetic: Uses magnets triggered by a magnetic object or field.
- Proximity Sensing: Optical, inductive, or capacitive sensors detect object presence without direct contact.
Activation changes the switch's electrical state (open or closed circuit), enabling control of machinery, signaling object presence, or setting limits on mechanical movement.
4. What is the voltage and current rating of the Mini Limit Switch 5A 250V?
The switch has a voltage/current rating of 5A 250V, ensuring reliable performance in various applications.
5. How many terminals does the Mini Limit Switch have?
It has 3 terminals, offering a momentary action switch with 1 NO and 1 NC contact for precise control.
