Occupy larger ratio in not, the convenience for bringing many can be used to user, but many ask is still suffered from during popularization and application
Topic, have impact on the development and popularization of such switch.Existing single channel controls wall touch switch more and is essentially relay（KA）Class and
IGCT（SCR）Class soft-touch control, it was found from Current electronic soft-touch control control of product circuit structure and control mode analysis, after
Electrical equipment（KA）Class and IGCT（SCR）Class is not ideal enough.
Relay（KA）The relay coil used in class wall touch switch must during adhesive and maintenance adhesive
Need have certain operating current, due to the load of single channel dual control, more control wall touch switch is largely low-power LED lamp,
The LED of electricity-saving lamp and fluorescent lamp etc., especially 1W, its operating current are less than the operating current of coil, can not inhale relay
Close, although the slightly larger light fixture of power can make relay adhesive and keep, the 60% of undertension rated voltage during work, the
Two lamps just can not adhesive.Nominal increase coil resistance can effectively reduce operating current, but for the relay of small package, inhale
Power is difficult to ensure that.Particularly inductance type fluorescent lamp, starter operating current before build-up of luminance is very small, the adhesive of relay coil one,
Electric energy is without supplement, the first storage capacitor repid discharge, circuit automatic clear, can not normal work, this is needed the first energy storage electricity
Hold and increase and select the starter of quick build-up of luminance, this not only adds volume, cost, and trouble is also brought to circuit design.When
So, maximally effective solution is selection twin coil magnetic latching relay, and operating current is equal to zero after adhesive.But this relay
The price of device is 3-5 times of common relay, and user is difficult to receive.
And current IGCT（SCR）Single channel dual control, the single channel of class control wall touch switch more, are typically all compared using function
