![]() ![]() Moreover, for our upcoming version, together with the Bluetooth 5.0 mesh launch in late 2018, we are targeting to support 80% or above led bulbs with 1W or above and it’s believed that this is the leading technology in the light switch market. Change the 2-wire (without neutral wire) installation to 3-wire (with neutral wire) installation (It’s the last option, we would recommend to change the bulb instead of changing the wiring). Wire the power stabilizer behind the lamp (free included in the package) 2. To make sure the Yoswit fits your home, we provide also the additional solutions to work with the exceptional incompatible bulb types: 1. Though we are working hard on being compatible with as many different types of bulbs as possible, as long as the MCU inside the smart switch needs power to work, there is still a chance the bulb flickers in whatsoever reason. The latest solution has been tested with over 200 different types and different brands bulbs and it can now support most of the well-known brands LED bulbs in 3W or above. Yoswit has started the research since 2012 and the solution is in the 3rd generation now. This enables you to still control the switch wirelessly (or manually) whether the bulb is on or off. This tiny current is enough to keep the switch and its wireless electronics powered and the device alive. There is a tiny electrical current flowing from Live through the switch, through the bulb and to Neutral. However, for the electronic switch, the actual circuit is not totally off. Therefore, it’s believed this is not a good solution and there are only limited products using this mechanism in the market.įor Method 2, it seems not possible when the circuit breaks. On the other hand, as the battery charge only when the light is on, if you don’t use the switch for a long vocation, it might not be able to power on through the remote control anymore. It’s near impossible to convince the consumer to replace the battery inside the switch with the electrician when the battery life finishes. However, the light switch lifetime is normally design for 10 years+. With appropriate care and use ( ), you should expect 2-7 years or 500-2100 times from most rechargeable batteries. However, there are a lot of problems ahead which one of the key issue is about the rechargeable battery life. The second drawing depicts when box 1 has three bundles of wire while box 2 has just one.In order to design a smart switch to retrofit the existing 2-wire installation, it’s either Method 1: putting a rechargeable battery inside the switch to supply the power to the MCU or Method 2: thinking out of the box to make MCU work with the 2-wire wiring system. It's the simple three-way circuit I anticipated and encountered in my home. The first is an outline of what you should see. All those switches, terminals and wires can confuse experienced electricians, let alone novice DIYers. It isn't uncommon either to have one three-way switch in the same box as two or even three others. One of your electrical boxes might have just one bundle of wires while the other is packed with three bundles. This scenario tends to happen with switches in older homes. For instance, there may not be any white wires. The wiring you see may not match what I've described. The wires here connect this local switch to the other in box 1 across the room. The light switch can either be a simple on/off switch or it can have multiple positions, allowing the user to select various brightness levels. A second bundle (four-wire) should contain three colored wires (black, white, red) and a copper (bare). A light switch is a device that is used to control the flow of electricity to a light fixture or other electrical outlet. These link the switch to your light fixture. One three-wire bundle will have two colored wires (black, white) plus one of bare copper. Besides their direction of entry the wires are constructed the same way. ![]() ![]() Here, both wire bundles should enter the electrical box from its top side. They connect the switch in this box to the other switch in box 2.īox 2. The other 4-wire bundle will enter the box from the top and have three colored wires (black, white, red) and a copper (bare) one. These wires come from your home's main electrical panel (usually in the basement below) and provide power to your lighting circuit. This three-wire bundle should consist of two colored wires (black, white) plus one of bare copper. In box 1, one of the wire bundles enters the box from the bottom. It will help you deduce their origin and ultimately identify them.īox 1. If so then the direction wires enter each box is important. Let's call each box "Box 1" and "Box 2." We'll also assume that, like mine, the boxes you're working inside are on a floor above the basement. Inside each of the two electrical boxes you should see two bundles of wires. This step-by-step is reflective of a common wiring scenario and the one in my own home. ![]() I must stress that there are many possible ways a set of three-way light switches can be connected. You should now have a good view inside each box. ![]()
