Pull wire switch ZS7310/1SWVD Pull wire switch ZS7310/1SWVD Pull wire switch ZS7310/1SWVD The switch mechanism is not in line with energy conservation and environmental protection. 1. There is no indicator light on the switch, which sometimes causes the lights to stay 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 improvement 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. In the future, the development of new types of pull wire switches will occupy the vast majority of the rural market. However, ordinary pull wire switches have a disadvantage: it is difficult to determine their on/off status during power outages, which often leads to unnecessary energy waste. I have slightly improved the shape of the ratchet of the pull switch, so that it is easy to determine the on/off of the pull switch without changing the structure of other parts of the switch and increasing costs. 1. The operation should be simple. 2. Functionality should be practical. 3. The appearance should be beautiful. 4. The position of the buttons should be clear and easy to operate. 5. Good stability, (using specialized signal lines for stability). 6. Installation should be convenient. 7. Maintenance should be easy. 8. The price should be affordable* Control operation function of; New intelligent display function; Unique safety protection functions; Easy installation, convenient maintenance, and affordable price: E12-20D0.1NK, E12-20D0.1NH, E12-20D0.1PK, E12-20D0.1PH, E12-20T3NK, E12-20T3NH, E12-20T3PK, E12-20T3PH, E18-20D0.1NK, E18-20D0.1NH, E18-20D0.1NT, E18-20D0.1PK, E18-20D0.1PH, E18-20D0.1PT, E18-20D0.1DK, E18-20D0.1DH, E18-34D0.1GK, E18-34D0.1GH, E18-20D0.1GH 20R3NK, E18-20R3NH, E18-20R3NT, E18-20R3PK, E18-20R3PH, E18-20R3PT, E18-20R3DK, E18-20R3DH, E18-34R3GK, E18-34R3GH, E18-20T10NK, E18-20T10NH, E18-20T10NT, E18-20T10PK, E18-20T10PH, E18-20T10PT, E18-20T10DK, E18-20T10DH, E18-34T10GK, E18-20T10T10K GH, E30 series: E30-20D1NK E30-20D1NH、E30-20D1NT、E30-20D1PK、E30-20D1PH、E30-20D1PT、E30-20D1DK、E30-20D1DH、E30-34D1GK、E30-34D1GH、E30-20R4NK、E30-20R4NH、E30-20R4NT、E30-20R4PK、E30-20R4PH、E30-20R4PT、E30-20R4DK、E30-20R4DH、E30-34R4GK、E30-34R4GH、E30-20T20NK、E30-20T20NH、E30-20T20NT、E30-20T20PK、E30-20T20PH、E30-20T20PT、E30-20T20DK、E30-20T20DH、E30-34T20GK、E30-34T20GH、E41-20D0.5NK、E41-20D0.5NH、E41-20D0.5NT、E41-20D0.5PK、E41-20D0.5PH、E41-20D0.5PT、E41-20D0.5DK、E41-20D0.5DH、E41-20R2NK、E41-20R2NH、E41-20R2NT、E41-20R2PK、E41-20R2PH、E41-20R2PT、E41-20R2DK、E41-20R2DH、E41-20T5NK、E41-20T5NH、E41-20T5NT、E41-20T5PK、E41-20T5PH、E41-20T5PT、E41-20T5DK、E41-20T5DH、E47-20D0.3NK、E47-20D0.3NH、 E47-20D0.3NT、E47-20D0.3PK、E47-20D0.3PH、E47-20D0.3PT、E47-20D0.3DK、E47-20D0.3DH、E47-20R2NK、E47-20R2NH、E47-20R2NT、E47-20R2PK、E47-20R2PH、E47-20R2PT、E47-20R2DK、E47-20R2DH、E47-20T5NK、E47-20T5NH、E47-20T5NT、E47-20T5PK、E47-20T5PH、E47-20T5PT、E47-20T5DK、E47-20T5DH、E50-20D0.3NK、E50-20D0.3NH、E50-20D0.3NT、E50-20D0.3PK、E50-20D0.3PH、E50-20D0.3PT、E50-20D0.3DK、E50-20D0.3DH、E50-34D0.3GK、E50-34D0.3GH、E50-34D0.3GJ、E50-20R2NK、E50-20R2NH、E50-20R2NT、E50-20R2PK、E50-20R2PH、E50-20R2PT、E50-20R2DK、E50-20R2DH、E50-34R2GK、E50-34R2GH、E50-34R2GJ、E50-20T5NK、E50-20T5NH、E50-20T5NT、E50-20T5PK、E50-20T5PH、E50-20T5PT、E50-20T5DK、E50-20T5DH、E50-34 T5GK、E50-34T5GH、E50-34T5GJ、 E52-20D0.3NK、E52-20D0. 3NH E52-20D0.3NT、E52-20D0.3PK、E52-20D0.3PH、E52-20D0.3PT、E52-20D0.3DK、E52-20D0.3DH、E52-20R2NK、E52-20R2NH、E52-20R2NT、E52-20R2PK、E52-20R2PH、E52-20R2PT、E52-20R2DK、E52-20R2DH、E52-20T5NK、E52-20T5NH、E52-20T5NT、E52-20T5PK、E52-20T5PH、E52-20T5PT、E52-20T5DK、E52-20T5DH、E57-20D0.3NK、E57-20D0.3NH、E57-20D0.3NT、E57-20D0.3PK、E57-20D0.3PH、E57-20D0.3PT、E57-20D0.3DK、E57-20D0.3DH、E57-20R1NK、E57-20R1NH、E57-20R1NT、E57-20R1PK、E57-20R1PH、E57-20R1PT、E57-20R1DK、E57-20R1DH、E57-20T5NK、E57-20T5NH、E57-20T5NT、E57-20T5PK、E57-20T5PH、E57-20T5PT、E57-20T5DK、E57-20T5DH、E60-20D0.5NK、E60-20D0.5NH、E60-20D0.5NT、E60-20D0.5PK、E60-20D0.5PH、E60-20D0.5PT、E60-20D0.5DK、E60-20D0.5DH、 E60-20R2NK、E60-20R2NH、E60-20R2NT、E60-20R2PK、E60-20R2PH、E60-20R2PT、E60-20R2DK、E60-20R2DH、E60-20T5NK、E60-20T5NH、E60-20T5NT、E60-20T5PK、E60-20T5PH、E60-20T5PT、E60-20T5DK、E60-20T5DH、   American Raytek: MT4, ST20XB,ST60XB,ST80XBRS,MX2C; Taiwan, China Hengxin: AZ8868, AZ8886，AZ8866，AZ8859，AZ8901，AZ8904，AZ8908，AZ8921，AZ8925，AZ8877,AZ9871，AZ8888，AZ8889，AZ8856，AZ8801，AZ82100; Huayi pressure gauge: YO60, YO-60，YY60，YY-60,Y60,Y-60，Y100，Y-100，Y150，Y-150，Y200，Y-200，Y250，Y-250; Seismic pressure gauge: YN60, YN-60，YN100，YN-100，YN150，YN-150，YN200，YN-200，YN250，YN-250; Magnetic assisted electric contact pressure gauge: YXC100, YXC-100,YXC150，YXC-150; Shock resistant magnetic assisted electric contact pressure gauge: YNXC100, YNXC-100，YNXC150，YNXC-150； Ammonia pressure gauge: YA100, YA-100，YA150，YA-150; Capsule pressure gauge: YE-60, YE60，YE60ZT，YE-60ZT,YE75,YE-75，YE100，YE-100，YE100ZT,YE-100ZT,YE-150; Stainless steel pressure gauge: Y60BF, Y-60BF,Y100BF,Y-100BF,Y150BF,Y-150BF; Sanitary diaphragm pressure gauge: Y100ML, Y-100ML，Y60M,Y-60M,Y100M,Y-100M; Aerospace plug/junction box type resistance remote transmission pressure gauge: YTZ150, YTZ-150, stainless steel film composite gauge: YE100BF, YE-100BF.YE100BFZT,YE-100BFZT,YE150BF,YE-150BF,YE150BFZT,YE-150BFZT; Remote thermometer: WTYY0-300, WTYY-50& 200; Pressure thermometer: WTZ280.WTZ-280, WTQ280，WTQ-280，WTZ288，WTZ-288; Bimetal thermometer: WSS301, WSS-301;WSS311，WSS-311，WSS411，WSS-411，WSS501，WSS-501，WSS451，WSS-451，WSS481，WSS-481，WSS581，WSS-581，WSSX301，WSSX-301，WSSX401，WSSX-401，WSS411N,WSS-411N; Rectangular membrane combined meter: YEJ-101, YEJ-121; Glass rotor flowmeter: lzb-3, lzb-4，lzb-6，lzb-10，lzb-15，lzb-25，lzb-40，lzb-40，lzb-50，lzb-80，lzb-100，lzb-15f，lzb-25f，lzb-50f，lzb-80f，lzb-100f，lzg-4，lzg-6，lzg-10，lzg-15，lzg-25，lzg-40，lzg-50，lzg-80，lzg-100； Marine pressure controller: YWK-50-C, YWK-50CYWK50C; Tractor thermometer: wyz-01; Thyristor adjustment tester: ZK-1, ZK-3，ZK-03;
