An AC high-current push-button power switch is a type of button switch that connects or disconnects an AC power supply by means of pressing and can safely carry and control relatively large currents (e.g., 10A or higher).

What is an AC push-button power switch?

AC High-Current Push-Button Power Switch It is a push-button switch that connects or disconnects an AC power supply through pressing operations and can safely carry and control relatively large currents (e.g., 10A or higher). Main features:

  1. High current rating: The rated current typically ranges from 10A to 16A.
    II. Long mechanical life: Certified electrical life of 10,000 cycles. The mechanical life can reach up to 50,000 operations.
    Three, Multiple protection levels: It can provide dustproof, moisture-proof, and flame-retardant protection, among other features.
    Four, Flexible contact form: Offers two functions: latching (self-locking) and momentary (self-resetting).
  1. Safety certifications: UL, CUL, NEMKO, CQC, ENEC, CB, and others.

Main application scenarios

Industrial equipment: power switches for automation equipment, power switches for high-voltage sensors.
Home Appliances and Consumer Electronics: Some high-power home appliances, such as electric heaters, electric pianos, speakers, floor-scrubbing robots, and vacuum cleaners.
Outdoor sector: lawnmowers, portable outdoor power banks, and more.

Precautions

1. Strictly prohibited to use beyond the specified specifications. Ensure that the actual operating voltage and current remain within the switch’s rated values.
II. Pay attention to the load type. Capacitive and inductive loads (such as motors and electromagnetic coils) generate currents that are significantly higher than their rated values when starting up. Inrush current An additional protection circuit needs to be designed.
Three, Proper installation and operation Pay attention to the mounting hole positions and actuation travel of the switch to avoid malfunctions caused by mechanical stress.
Four, Ensure electrical safety. Circuit design and installation must be carried out by qualified professionals to ensure reliable grounding, and consideration should be given to installing fast-blow fuses at the input end.

Selection and Usage Recommendations

To ensure the switch operates stably and reliably, you’ll also need to pay attention to the following points when selecting and using it:

I. Precise Matching of Electrical Parameters When selecting a switch, Operating voltage and current Sufficient margin must be reserved to accommodate potential current fluctuations. At the same time, the load characteristics (resistive, capacitive, or inductive) should be evaluated accordingly. Inrush Current Risk and take corresponding mitigation measures.

II. Emphasize Protection Ratings and Environmental Conditions Based on the operating environment of the equipment, select one that has the corresponding features. IP protection rating switches. For example, in outdoor environments or industrial settings that are humid and dusty, switches with an IP65 or IP67 rating should be selected to ensure safety.

III. Ensure Compliance and Safety Be sure to confirm that the switch has passed the relevant tests. Security certification such as UL, CUL, CQC, ENEC, and others. During installation and use, it is essential to comply with electrical safety standards, for example: Correct grounding , use the appropriate one Fuse Wait.

Application Scenarios and Precautions for AC Power Sockets

An AC power outlet—commonly referred to simply as a “socket” or “power outlet”—is an electrical interface installed on walls, floors, or portable devices, designed to safely connect household or industrial AC power to a wide variety of electrical appliances. Its core components and functions are as follows: AC stands for “Alternating Current.” This refers to an electric current whose direction and magnitude vary periodically over time. Unlike “Direct Current,” which is supplied by batteries in our daily lives, the electricity transmitted from the power grid to homes and businesses is predominantly AC, as it is better suited for long-distance transmission.

Applications and Precautions for Rotary Switches

A rotary switch is a electromechanical component that changes the state of circuit connections by rotating a handle or knob. Its core internal structure consists of a rotating shaft (rotor) and multiple stationary contacts (stators). When you turn the knob, the brushes or contact blades on the rotor connect to or disconnect from different stator contacts, thereby closing, opening, or switching various circuits. The switch has positions ranging from 1 position to fully open, with rotation angles of 30°, 36°, and 45°. The base types come in two outer diameters: Φ32 and Φ29.
