Air Fryer E43 Microswitch Working Principle
The E43 microswitch is a complex process that combines mechanical and electrical principles and plays a vital role in ensuring the safe and efficient operation of air fryers. E43 microswitch is mainly composed of switch body, spring, contact, terminal and other parts. These components work together to achieve precise control of the power supply to the air fryer. E43 microswitches are widely used in home appliances, electronic equipment and machinery for their advantages of high safety, small contact resistance and long life.
In the air fryer, the E43 microswitch is usually installed on the door lock device or the inner bucket lifting mechanism to detect the position state of the food basket or inner bucket, and accordingly control the power supply of the air fryer. When the food basket is properly placed in the air fryer cavity, or when the inner bucket is in a specific position, the E43 microswitch triggers the circuit to close, enabling the air fryer to power up; Otherwise, the power supply is cut to prevent the air fryer from operating unattended or unsafe.
Before the air fryer is started or the food basket is placed, the E43 microswitch is turned off and the power to the air fryer is cut off. In this case, keep a certain distance between the contact and the wiring terminal to ensure that the circuit does not work. When the user pushes the food basket horizontally into the cavity of the air fryer, the bottom or edge of the food basket touches the triggering mechanism (such as the CAM element) of the E43 microswitch. This touch action drives the push rod inside the E43 microswitch along the vertical axis.
As the push rod moves, the contacts inside the E43 microswitch gradually approach and eventually contact the terminal, thereby closing the circuit. At this point, the power supply to the air fryer is switched on, and components such as heating elements and fans begin to work, cooking the food. In some high-end air fryers, the E43 microswitch is also used to control the lifting of the inner barrel. When the inner bucket is raised (such as when removing the food basket), the CAM at the bottom of the inner bucket makes contact with the contact of the E43 microswitch, triggering the switch to change state and cut off the power supply. This ensures that no accidental start or continuation of heating occurs when the inner drum is moved, thus protecting the safety of ingredients and users. When cooking is complete or the user needs to remove the food basket, simply pull the food basket out of the cavity. With the removal of the food basket, the triggering mechanism of the E43 microswitch is no longer under pressure, the push rod will return to the initial position under the action of the spring, the contact and the terminal are separated, and the circuit is disconnected. At this point, the air fryer stops working and goes into standby.
First, the classification of E43 microswitch of air fryer
Air fryer E43 microswitches are generally divided into two types, mechanical E43 microswitches require manual operation by the user, such as pressing or rotating, to open or close the air fryer. When the inner barrel of the air fryer is raised, the CAM at the bottom of the inner barrel makes contact with the contact of the E43 microswitch, thereby changing the state of the switch and cutting off the power to protect the food and equipment. When the inner barrel is lowered, the contacts return to position, and the air fryer is re-energized and returned to working condition. The other is the electronic E43 microswitch and mechanical different, electronic E43 microswitch through computer control to achieve automatic opening and closing function. It does not require manual operation by the user, but automatically controls the switch of the air fryer according to a preset program or sensor signal.
Second, air fryer E43 microswitch structure and material
Air fryer E43 microswitch is usually composed of switch body, spring, contact, terminal and other parts. Among them, the spring is mostly made of pure silver gold-plated (or nickel-plated), which can maintain good elasticity and toughness at high temperatures and is not easy to deform and damage. At the same time, the design of the contact part also ensures that the contact resistance is small, improving the reliability and service life of the switch.
Third, air fryer E43 microswitch installation and precautions
When installing the air fryer E43 microswitch, set the knob in the air fryer to “off” and secure the knob. Unscrew the nuts at the bottom of the air fryer. Tighten the screws on the knob. Remove the plastic cover above the knob. Use the tool to align and insert the top two holes. Align the four holes in the lid and insert them firmly. Tighten the lid with your hand.
Do not exert too much force, so as not to cause product failure. After each use, clean it and then put it back on. Do not use in humid environments. Don’t scratch metal with sharp objects.
Advantages and applications of E43 microswitch in air fryer
Air fryer E43 microswitch has the advantages of high safety, low contact resistance and long life, so it is widely used in household appliances, electronic equipment, machinery and other fields. In the air fryer, the application of E43 microswitch not only improves the safety of the equipment, but also facilitates the use of the user. For example, some air fryers with E43 microswitches automatically power off when the barrel is pulled out, making it easy for users to cook, add ingredients and flip food; When the bucket is put back in place, the air fryer automatically returns to the cooking state without the user having to set it again.
The application of E43 microswitch in the air fryer not only improves the safety and reliability of the equipment, but also simplifies the operation process of the user. With precise position detection and circuit control, the E43 microswitch ensures that the air fryer starts and stops at the correct time and condition, thereby avoiding safety hazards caused by misoperation or equipment failure. In addition, the long life and stable performance of the E43 microswitch also guarantees the stability and reliability of the air fryer during long-term use.
Air fryer E43 microswitch is one of the important components in air fryer, its classification, working principle, structure and material, installation and precautions as well as advantages and applications are worth our in-depth understanding.
