Micro waterproof switch is a kind of small contact distance, switch action fast waterproof switch, the switch has the specified stroke and the specified force. It is covered by a housing with an external drive lever. Yes: In the waterproof microswitch type, the function of the switch is achieved by mechanical switching of contacts, as compared to semiconductor switches that have the characteristics of waterproof microswitches. Working principle: The external mechanical force acts on the action reed through the transmission element (press pin, button, lever, roller, etc.). When the action reed moves to the critical point, the action takes place instantly, making the movement and fixed contact of the end of the action reed act. Turn it on and turn it off. When the force acting on the transmission element is eliminated, the acting spring produces reverse force. When the reverse stroke of the transmission element reaches the critical point acting on the reed, the reverse action is immediately completed. The utility model has the advantages of small contact distance, short stroke, small pressure and fast switching speed. The moving speed of the moving contact is independent of the moving speed of the transmission element. Important parameters: 1. Anti-leakage index. When two electrodes are inserted into the sample and 50 drops of the specified solution (0.1[%] ammonium chloride) are dropped between the two electrodes, no short circuit occurs, which is the maximum tolerable voltage value, divided into five grades. 2. Operation time: refers to the opening and closing time of durability test specified in the specification. Each manufacturer selects the time from the table below, indicated by the symbol on the switch. In the IEC specification, the standard is 50,000 times for switches operated at high frequencies and 10,000 times for switches operated at low frequencies. 3. Operating environment temperature: The temperature range that the switch can use. Application: Waterproof micro switch is widely used in a variety of cold, wet, dusty and harsh environment. Such as automobiles, spraying equipment, etc.

What's the difference between a touch switch and a micro switch? Touch switch general touch mode is click click type, the connection is disconnected instantly, the effect is relatively simple. Generally, it is suitable for single on-off (click-click-click connection off) of micro electrical products, and the micro switch has a variety of functions. It can be broken into a power circuit, can also be normally switched on, and can also be used as a power switch for detection. In other words, the micro switch can completely replace the touch switch, the most important is the cost.The whole working process of the micro switch is: when there is no external force, the switching isolation switch is in the same position. When the external force is released to make the transmission rod extend out, the bow spring will deform and store mechanical energy, resulting in deviation. When it reaches the ordered zero boundary point, the spring plate is connected to the dynamic isolation switch, producing a momentary jump, resulting in the power supply loop on, off or switch. After the elimination of external force, the spring will release mechanical energy, resulting in reverse deviation. When another zero boundary point is used, the isolation switch automatically corrects under the action of the spring plate.Microswitch function1. Although the specifications and models are small, the total power flow of the power switch can be large.Normally, when the electronic circuit is closed, a flame, whose full name is arc light, is generated between the contacts. The larger the total current is, the more likely it is to cause arc light, the slower the contact change speed and the longer the arc light delay, which are all factors leading to the deterioration of contact. The quick action mechanism of the micro switch can change the contact instantaneously, so the arc delay is short. Although the specification model is small, but can be used as the total current is very large power supply circuit.2. Precision machiningEven if the micro switch continues the on/off operation process, it can basically change the contact in the same position, so the position detection error is small, and it can be used in the application range requiring precision machining. This is also the unique advantage of micro switches with quick action mechanism.3. Performance indicatorsBecause the arc delay is short, the damage to the contact is relatively small, so the performance index is improved.4. Touch and soundThe quick mechanism has abnormal touch and sound in the operation process, so the operation process can be defined according to the feel and hearing system software.Characteristics of large, medium and small microswitches1. Pocket, light and precision machining.2.m3 mm with practical screws.3. In addition, the use of special-shaped terminals and standard spacing structure, so that the welding wire and flux can not invade the power switch inside.4. Also need to have a small power supply circuit type (au cable sheath point contact), can be loaded with minimum current intensity.5. Independent terminals, which can be installed on the printed packaging board. The main body of the power supply is separated from the printed packaging plate with a diameter of 1.2 ~ 1.6 mm.6. The product series of the right corner terminal and the left corner terminal of the printing packaging board is also necessary.7. Comply with rohs instruction.
