Waterproof Micro Switch Detection Sealing Testunionwellswitch
A waterproof micro switch and sealing waterproof tests are essential during micro switch production. The micro switch is a contact and quick-action mechanism with a small contact distance, which can be switched with a specified stroke and force.
The contact distance of the waterproof microswitch is relatively small, so the corresponding housing is generally relatively small. Most of these micro switches are used in the external environment, so they need good waterproof performance. Otherwise, it will cause a short circuit failure and affect the use once immersed in water. Therefore, it is necessary to use a waterproof micro switch air tightness detector. Waterproof test, testing sealing performance.
What are the waterproof micro switches and sealed waterproof tests?
A waterproof micro switch is a pressure-actuated snap switch, also known as a sensitive switch. Its working principle is that the external mechanical force acts on the action reed through the transmission element (push needle, button, lever, roller, etc.).
After the energy is accumulated to the critical point, an instantaneous action is generated. At the end of the action reed, the moving contact is quickly connected or disconnected from the fixed contact.
When the force acting on the transmission element of the waterproof micro switch is eliminated, the acting reed generates a reverse force. When the transmission element’s reverse stroke reaches the reed’s critical point, the reverse action is completed instantly. The micro switch has the advantages of small contact distance, fast action stroke, small pressing force, and fast on-off. The moving speed of the moving contact has nothing to do with the moving speed of the transmission element. The basic type of micro switch is pushpin type, which can be derived from button short-stroke type, button large stroke type, button different stroke type, roller button type, reed roller type, lever roller type, short arm type, long arm type, etc. . Micro switches are used in electronic equipment and other automatic control and safety protection equipment that requires frequent switching of circuits.
Microswitches can be divided into large, medium, and trim. Different needs can be divided into waterproof and ordinary types according to different needs. Waterproof micro switches connect two lines to provide switch control for appliances and machines.
The waterproof micro switch and the airtightness test of the microswitch generally use a soft sealing material to seal the periphery of the bottom of the product at the inflated position at the bottom of the product. Waterproof micro switch test. If the airtightness of the product is good, there will be no outside air entering the interior, and the negative pressure will always be maintained at a specific value. If the sealing performance of the product is not good, that is to say, if there is a leak, the outside air will enter the interior, and the negative pressure will change. If you use a waterproof tester, it indicates continuous air bubbles in the tank. In this way, through the waterproof micro switch test and the waterproof test of sealing, it can be concluded whether the product’s waterproof performance meets the requirements.
