A waterproof micro switch, which is a contact structure with a small contact interval and a snap-action mechanism for switching operation with a predetermined stroke and a predetermined force, is covered by a casing, and the waterproof micro switch has a casing. The drive rod is outside it. With contacts: In the type of waterproof micro switch, the function of the switch is realized by the mechanical switch of the contacts, compared with the semiconductor switch with the characteristics of waterproof micro switch.
One of the many accessories of the gas water heater is the waterproof micro switch of the gas water heater. The name seems to be a micro switch. In fact, the waterproof micro switch of the gas water heater has its special structure. Its working principle determines the protection and control of the gas water heater. The waterproof micro switch for gas water heaters is an external mechanical force, the force acting on the gearbox components (through pins, buttons, rollers, etc.), accumulates energy to a critical point, and produces an instantaneous action to move the end of the action piece. Contacts and fixed contacts can be opened or closed quickly. When the force on the transfer element is removed, the action reed produces a reverse force, and when the reverse stroke of the transfer element reaches the critical point of action of the reed, the reverse action is terminated immediately. The contact between the microswitches is small, the travel is short, the power is small and the switch is active. Micro switches are used in electronic equipment and other equipment, such as automatic control and safety protection of frequently changing circuits.
1. The gas water heater must be used to clean and protect the product operation manual, and use the water heater according to the instructions on the manual and the nameplate, as well as simple preliminary water heater maintenance, cleaning and protection, etc.
2. When the gas water heater has air leakage, water leakage, the flame does not go out after the water is cut off, and the incineration working conditions are poor, it should be used continuously in some cases to notify the gas treatment or repair manufacturer, and prevent private opening and maintenance.
3. Do not use expired water heater cleaning and protective agents. According to the national standard GB17905-1999 "Safety Handling Regulations for Household Gas Incineration Appliances", from the date of sale of gas water heaters, the cleaning protection effectiveness of liquefied gas and water heaters is judged for 15 years. Years, the cleaning protection of artificial gas water heaters is valid for 10 years.
4. Make sure the room is well ventilated and ventilated.
5. Be punctual, please carry out gas treatment. Some designated professionals or manufacturers should clean and protect the gas water heater, and repair it in time. Only by insisting on cleaning and protecting the gas water heater can it play an outstanding role.
