A microwave oven is an electrical device that can quickly heat food. It mainly generates high-frequency electromagnetic wave fields, which cause high-speed oscillation and mutual friction of molecules in the object to be heated. of. Therefore, users often have one or another worry and doubt about electromagnetic wave leakage and radiation when purchasing microwave ovens. However, in fact, the radiation of microwave ovens does not have such hazards as X and γ rays, and the production and manufacture of microwave ovens have strictly controlled the radiation. However, in order to prevent the microwave from burning the human body due to misoperation or negligence, a micro switch is still added to the door of the microwave oven for protection.
Generally speaking, there are three micro switches in the oven door structure of microwave ovens, which are primary, secondary latch switch and safety monitoring switch. Among them, the primary and secondary safety switches respectively trigger different circuit states when the furnace door is opened and closed, thereby affecting the connection and disconnection of the power supply of the induction cooker. When any one of the micro switches shows that the oven door is not properly closed or not closed properly, the microwave oven cannot be started normally, thus avoiding microwave leakage. In this door-linked switch, there is another monitoring switch for its protection. Its main function is to prevent the upper and lower safety switches from being damaged and short-circuited normally. In this way, even if the state of the furnace door cannot be correctly displayed due to damage or failure of the two door switches, there is still a safety switch for protection.
The Olga Electronics standard microswitch SM series is designed to significantly improve reliability. This series of switches is generally suitable for low-cost-to-failure applications where the cost of replacing a switch or repairing a switch-related fault is very low. The SM is designed for a variety of applications requiring greater than or equal to 100 g operating force and current ratings from 16 A to 22 A. SM Series switches are available in a variety of standard configurations including a choice of actuators, current ratings, operating forces and circuits, and have global approvals (ENEC, CQC, UL and cUL).
