Micro Limit Switch

Micro Limit Switch

Micro Switches are generally based on the basic type without an auxiliary press attachment, with derivatives for  small and large stroke types. Depending on the need, different auxiliary push assist parts can be added. Depending on the different press-assist components added to the Switch, they can be categorized into push-button, spring-roller, lever-roller, short-arm, and long-arm forms.

micro switches are used for control and protection in equipment that requires frequent circuit switching, and are widely used in electronic equipment, instrumentation, power systems, household appliances, electrical equipment, security, automotive and other fields.

Features

Rated Voltage: 250V AC and 125V AC This micro switch is rated to operate at two different AC voltage levels, 250 volts and 125 volts. These voltage ratings indicate the maximum electrical potential difference the switch can safely handle during operation. The dual voltage rating makes the switch suitable for a wider range of devices and systems that may operate at different voltage standards, ensuring compatibility and safety in various electrical environments.

Rated Current: 3A at 250V and 5A at 125V The switch has a current rating of 3 amperes when operating at 250 volts and 5 amperes at 125 volts. This means it can handle different current loads depending on the voltage it is used with, providing flexibility in its application. The current ratings are crucial for determining the power capacity of the switch and ensuring it can manage the electrical load of the connected devices without overheating or failing.

Rated Frequency: 50Hz Designed to operate at a frequency of 50 hertz, this switch is compatible with the standard power supply frequency used in many countries and regions. The frequency rating ensures that the switch can function correctly in synchronization with the alternating current cycles, which is essential for the proper operation of electrical devices and the prevention of malfunctions or damage.

Contact Resistance: Maximum of 30 milliohms The contact resistance of the switch is kept to a maximum of 30 milliohms, indicating a very low resistance when the switch is in the closed position. Low contact resistance is vital for minimizing energy loss and voltage drop across the switch, ensuring efficient transmission of electrical current and maintaining the overall performance of the electrical circuit.

Insulation Resistance: Minimum of 2 megaohms at 500V DC With an insulation resistance of at least 2 megaohms when tested with a 500-volt direct current, this switch demonstrates excellent insulation properties. High insulation resistance prevents unintended current leakage and electrical shorts, enhancing the safety and reliability of the device. It ensures that the switch can maintain the separation between conductive parts and prevent dangerous electrical faults.

Dielectric Strength: AC 1800V per minute at 50Hz The dielectric strength of the switch is rated at 1800 volts AC per minute at 50 hertz. This rating signifies the switch's ability to withstand high voltage without electrical breakdown, which is crucial for its safe operation in environments where it may be exposed to voltage surges or transient overvoltages. It ensures the switch can reliably isolate electrical conductors and prevent arcing or current flow where it is not desired.

Working Environment: Temperature range of 25T85 The switch is designed to operate within a temperature range denoted as 25T85. This indicates that the switch can function effectively in environments where the temperature varies within this specified range. The ability to operate across a range of temperatures makes the switch suitable for use in different climates and operating conditions, ensuring consistent performance whether in cooler or warmer settings.

Service Life: 5000 cycles The expected service life of the switch is 5000 cycles, which refers to the number of times it can be turned on and off before potential wear and tear may affect its performance. A longer service life means the switch is built to endure a significant amount of use, reducing the frequency of replacement and maintenance. This durability is essential for applications where the switch is frequently operated, ensuring reliability and cost-effectiveness over time.
