Some problems to be avoided in welding toggle switch
Release time：2018-12-05 Clicks： Click
Some problems should be paid attention to when welding the switch to avoid these problems. Details of the welding switch are described in detail below.
1. be careful with chemicals.
Due to the use of synthetic materials such as polycarbonate, the bottom plate of the switching switch should avoid exposing the potentiometer to the strong atmosphere of chemical products such as ammonia, amine, alkali solution, threone, ketone, ester and halogen.
2. caution with flux.
Water soluble flux should be avoided in soldering, otherwise it will have adverse effects on the metal and other materials that make up the switch.
The wiring design and soldering method of the switch should avoid causing the molten tin to flow to the plane of the PC board, which will cause bad contact.
4. working at low temperature.
When the product is used in low temperature environment, such as car radio or car audio in cold zone, our company provides comfortable products according to customer's requirements, please explain when ordering.
5. sliding handle length.
The shorter the length is, the better (at least 5 mm). The shorter the length of the sliding handle is, the better the hand feeling is. The higher the output point is, the worse the hand feeling is.
6. drive arm.
Never keep the operating point away from the center line of the slider. For the same reason, the shorter the distance between the two points, the better.
The manufacturer of micro-switch introduces that it is easy. This kind of switch should be connected by two terminals. The other three terminals are connected by switches. Find out the terminals of the lights and the terminals of the switches, and then distinguish which two terminals you want to use to connect the switches. Chain the lights directly with the switch terminals, so that when the switch is connected, the lights will also be connected. Turn on the switch.
The four pins of the micro-toggle switch are normally open and normally closed respectively. Which two pins to use depends on the requirements of the circuit. For example, an easy self-locking circuit is the constant closure of a key as a stop, and a key is usually opened as a start. In the case of not pressing the key, it is called normal closure of the connection, and after pressing the key, it will be called normal closure of the connection. It's broken.
In the absence of pressing the button, the disconnected call is often turned on, and after pressing the button, it is connected, of course, with a multimeter.
