Touch Switch, is an emerging product of technological development. It generally refers to a type ofWall Switch, which is a replacement for traditional mechanical button wall switches. Touch switches that can achieve smarter and more convenient operation have incomparable advantages over traditional switches and are a very popular decorative switch in home products. Today, the touch switch manufacturer Tongke Technology will discuss the classification and technical bottlenecks of touch switches.

1. Classification of Touch Switches

Touch switches can be classified by switching principle into resistive touch switches andcapacitive touch switches, and by wiring method into single live wire touch switches and double wire touch switches (live wire and neutral wire). Globally, the vast majority of countries adopt single live wire wiring rules, so early touch switches were mainly controlled by single live wire. As applications deepened, the stability of neutral and live wire control became higher, and the load of the switch increased. Currently, the market is dominated by neutral and live wire control.

2. Technical Bottlenecks of Touch Switches

Touch switches are a type of smart control wall switch that consumes a certain amount of electrical energy. In standby mode, the single live smart switch draws power through the current flowing through the electronic ballast to supply power to the control circuit of the smart wall switch. If the standby input current is too low, the standby circuit will not work; if the standby input current is too high, it can cause issues such as cold flash after the electronic ballast lamp is turned off or red filament problems after incandescent lamps are turned off. During operation, the single live smart switch draws power through the voltage difference at both ends when the switch is open. When the switch is closed, there is no voltage difference, and it cannot draw power, leading to loss of control of the circuit. Therefore, the technical challenge of power supply for single live wire touch switches has always existed, and the development difficulty of micro-power single live wire standby and working power supply circuits is very high. This is the main technical bottleneck limiting the development of single live wire touch switches both domestically and internationally.

To achieve a truly capacitive sensing touch switch, stable single live wire power processing and reliable touch sensing chips are required, along with features such as anti-misfire, resistance to various electromagnetic interference, load interference, environmental interference, and even waterproof and dustproof functions.Touch Switch Functions, and integrating sensing touch functionality into system solutions is a technical challenge in the industry.
