Since the waterproof micro switch has become more and more advanced in design, the application scenarios for installation and use have continued to increase. There are many technical points that need to be mastered in the process of installation and use, so that abnormal phenomena will not occur during debugging. Especially the switch control will be more accurate and reliable. Next, the WEIPENG will introduce to you what technical points should be mastered during the installation of the waterproof micro switch:

Key point 1: When tightening the waterproof micro switch, you need to choose stainless steel screws, which are durable, rust-proof and reliable, and you need to use washers to cooperate to achieve a more tightening effect. Therefore, in the installation of waterproof micro switch, it is necessary to master the technical key points of fastening, so that it can be firmer and safer, and the service life will be longer and longer. Then, strictly check the details of installation and fastening to ensure that there will be no looseness during use.

The waterproof micro switch is a quick change-over switch actuated by pressure. The waterproof micro switch is covered by a shell and has a drive rod outside. Because the contact distance of the switch is relatively small, it is called a micro switch. This time, Tongda Electronics introduced the key points of using waterproof micro switches (FSK-14 series, FSK-18 series, FSK-20 series).

1. The waterproof micro switch cannot be repeatedly operated by applying gravity. If the handle button has been pressed and further pressurized, the excessive load weight may cause deformation of the reed (shrapnel) of the waterproof micro switch and cause malfunction.
2. In particular, if an excessive load is applied to the horizontal pressure type, the riveting part will be damaged, which will cause damage to the waterproof micro switch. Therefore, when installing and operating the waterproof micro switch, please be careful not to add a load higher than the excessive load (29.4N, 1 minute, 1 time).
3. Please set the waterproof micro switch according to the direction that the handle can move in the vertical direction. Pressing only one side of the handle or operating diagonally may result in reduced durability.
4. The waterproof micro switch is dusty. Because it is a switch without a sealed structure, please do not use the waterproof micro switch in dusty places.
Yueqing Tongda Cable Power Plant focuses on the production and sales of micro switches, waterproof micro switches, rocker switches, push button switches and custom switches. Welcome to consult and cooperate!

Working principle: A micro switch is a quick switch actuated by pressure, also called a snap switch.
External mechanical force acts on the action reed through transmission elements (press pins, buttons, levers, rollers, etc.), and after accumulating energy to a critical point, it produces instantaneous action, making the moving contact at the end of the action reed and fixed contact Click to quickly turn on or off.
When the force on the transmission element is removed, the action reed produces a reverse action force. When the reverse stroke of the transmission element reaches the critical point of the action of the reed, the reverse action is instantaneously completed.
The contact distance of the micro switch is small, the action stroke is short, the pressing force is small, and the on-off is rapid.
The speed of the moving contact has nothing to do with the speed of the transmission element. The micro switch is based on the pin type, and can be derived from the button short stroke type, button large stroke type, button extra large stroke type, roller button type, reed roller type, lever roller type, short boom type, and long boom type. and many more.
Purpose: Micro switches are used in electronic equipment and other equipment for automatic control and safety protection devices that require frequent circuit switching.
Micro switches are divided into large, medium, and small. According to different needs, they can be divided into waterproof type (used in liquid environment) and ordinary type. The switch connects two lines to provide power on and off control for electrical appliances and machines. Widely used in household appliances, industrial machinery, new energy vehicle charging guns, communication equipment, military products, testing instruments, gas water heaters, floating ball equipment, medical equipment, building automation, power tools and general electrical and radio equipment, 24-hour timing Micro switches are small, but they play an irreplaceable role.
