EX-T3Z 068-11YR Pull Cord Switch EX-T3Z 068-11YR Pull Cord Switch Disadvantages Traditional switches have drawbacks in daily operation: 1. There is no centralized control on each switch, which cannot achieve control of all lights with one switch. Especially when guests come to visit and want to enter a room that has not yet turned on the lights, it is often difficult to find the switch. 2. Ordinary switches cannot achieve three control or multiple control operation functions. 3. There are no indicator lights on each switch, and the status of all lights cannot be displayed. 4. There is no power outage protection function, which poses a safety hazard. 5. Without remote control function, the larger the room, the more inconvenient it becomes. Turning on (off) the lights when waking up on a cold night is a very annoying thing. 6. There is no simple way to achieve full on/off operation. 7. The installation quantity of ordinary switches is relatively large, which brings a very uncomfortable feeling to the whole, and also adds a lot of trouble to installation, design, and wiring. 8. It is impossible to change the control object of a switch. 9. Adding lights and switches to a renovated house can damage the decoration. The switch mechanism of EX-T3Z 068-11YR pull switch is not in line with energy conservation and environmental protection. 1. There is no indication of the status of the electric light on the switch, which can sometimes cause the electric light to remain on and waste energy. 2. Due to the inconvenience of turning off the lights, they are not turned off in a timely manner and consume electricity. 3. Unable to automatically delay turning off the lights, it consumes electricity and is troublesome. 4. The use of metal contacts can sometimes cause electric arcs and sparks. After collecting the problems that need to be improved for ordinary dual control switches, we focused on analyzing why most households still cannot accept the existing smart switches in the market. After investigation, it was found that some smart products that can be seen in the market can only solve some of the problems they have raised. For most families, what they bring is not practical convenience, but complexity (elderly and children who are accustomed to using ordinary switches do not even utilize their functions), and the problems are still everywhere: 1. The concept of a total control box at the head of a hotel bed is complex in connection and can only be controlled in one room, which is not suitable for large houses. 2. A single remote control light cannot achieve networked control, and a single remote control cannot control all lights. 3. A separate dimming (delay) switch only dims (delays), without a memory function, and cannot automatically delay (dimming) or perform other advanced operations. 4. Intelligent lighting systems under CE BUS, IBUS or other protocols require professional wiring and specialized training to be used and installed. The advantage is strong signal line stability. 5. Wireless switches use radio frequency to transmit signals, and they are often affected by radio frequency interference, causing their frequency to become unstable and lose control. They also require encoding and decoding settings, making the operation very cumbersome. There are many additional devices with high prices, such as a variety of switch types, and the need for receiving modules, modems, centralized controllers, etc. 6. The power carrier switch uses power line transmission to send signals, and the switch needs to be equipped with encoding and decoding, which can be affected by power line noise interference, making its operation very unstable and often causing the switch to lose control. There are many additional devices with high prices, such as a variety of switch types and the need for wave arresters, filters, etc. 7. There are also smart switches in the market that are 6-bit, 8-bit, etc. The 6-bit and 8-bit smart switches are only suitable for 6-way and 8-way lights in a house, which cannot meet the needs of users to control all lights.
