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.
