Now many children's toys are required to connect the switch, if you are more familiar with this area, you know how to connect children's toy switch, but many people in this area is not very well understood, so the children's toy switch how to connect the problem is not a very good understanding of how to engage in, so children's toy switch how to connect it?
Children's toy switch how to connectConnect 1 foot and 2 feet, or 2 feet and 3 feet, at least one needs to be connected to the 2 feet can be. Toggle switches are used to switch circuits by toggling the switch handle to make the circuit on or off, thus achieving the purpose of switching circuits. Toggle switch commonly used varieties of single-pole double-position, single-pole three-position, double-pole double-position, as well as double-pole three-position, etc., it is generally used for low-voltage circuits, with the slider action is flexible, stable and reliable performance characteristics, toggle switches are mainly widely used in: a variety of instruments / instrumentation equipment, a variety of motorized toys, fax machines, audio equipment, medical equipment, cosmetic equipment, and other electronic products in the field.
Materials: multimeter, cold press pliers, screwdriver one word, screwdriver cross, peeling pliers, soldering iron, hair dryer, scissors. Fuse, heat-shrinkable tube, electrician insulating tape, screws,, socket terminals, connecting wires, rosin, solder, zip ties. AB 2-in-1 glue, transparent tape, foot starter, children's battery car special charger, 12V special battery, 16V470U.
First, the battery will be put back in its original position, and replace the brand-new special fuse on the machine. Open the front cover of the car, weld the broken wires, and put all the disconnected plugs back in the original position. Use a soldering iron to solder the speaker wire and connect the battery terminal. Then the explosion of the capacitor removed, according to the original capacitor voltage and capacity of the replacement, the original car for the 16V470UF electrolytic capacitors. Double-check the whole car, there is no serious short-circuit conditions, power test. Found that the whole car is not energized, measuring the battery voltage of 12V or so, after the power failure to measure the key door switch, there is a contact break, replace the new key door to re-test, found that the power can be energized, but the sound of the start is not normal intermittent, and the motor can not be started. Suspected battery problems, to determine whether the battery is normal, take a simple approach, that is, with a high-power DC bulb, directly connected to the battery at both ends, then found that the bulb momentarily bright, and then slowly darken, and more and more dark, indicating that the battery has no load carrying capacity. Although the measured voltage is normal, but no normal current can not drive the battery car after connecting the circuit. (The owner did not bring the new battery)
Children's toy car glitches how to do1. Battery dead lead to slow (just bought or 1 year or so)
Solution: "Replacement" battery or charging can be ruled out.
2. speed switch problems lead to slow speed (half a year or so common failures)
Solution: toggle the switch to drive, observe whether there is a speed change, if there is a change in the switch is not a problem. If there is no change, the switch is damaged and needs to be replaced, or the switch will be pulled out of the back of the two wires directly connected, it can be fixed in the fast when the position.
3. drive wheel wear serious slowdown (1 year)
Solution: drive wheel wear serious, resulting in a smaller circumference of the drive wheel, then the distance traveled per unit of time will become shorter, so the feeling of slowing down, replacement of the drive wheel and the rear wheel can be troubleshooting.
4. poor contact between the motor rotor and the carbon brushes (about 2 years)
Solution: common when not walking or a punch a punch goods start driving, clean the rotor and carbon brush position can be solved.
5. Wheel bearings are bad, resulting in slow speed (common failure)
Solution: check whether the wheel is shaking left and right, such as left and right shaking, replace the wheel bearings can be troubleshooting.
Solution: Check whether the wheel is swaying left and right, and replace the wheel bearing to eliminate the problem.
