There are various kinds of control unit for a dimmer available in the market, as an illustration, push switch, rotary switch, remote control with keys and touch control panel. Among them touch dimmer switch is a newly emerging technology that allows smooth control by simple finger touch.
The great advantage of a touch dimmer is easy and simple operation by just slight finger touch. All operations including switching on/off, adjusting brightness and adjusting colors are done by simple finger touch. Generally a dimmer switch with touch interface shall be designed with icons which can be easy to grasp and clearly indicate the functions. It is designed with ultra sensitive glass touch panel which allows accurate and fast brightness adjustment. The switching on/off and dimming operation may be quite smooth with none flickering.
Multi-zone control function may be available for the touch dimmer, it may switch and dim all these zones separately or synchronously without any confusions. As an illustration you can control the sitting room, bedroom, kitchen and bathroom together or independently. The touch panel might be available with different output signals so that the control distance varies. While designed with RF signal and match with a dimmer with RF signal receiver, the distance will be over 20 meters. Further distance can be possible while it is designed with signals that require wiring with the dimmer, for instance, DMX, 0-10V or DALI. For home lighting control RF signal is enough.
The touch dimmer switch is designed for not only monochrome LEDs, but in addition dual color (warm white and cold white) one and RGB/RGB(W) one. When controlling monochrome lamps, it offers basic switch and dimming functions and enables multiple zone operation that means one controller can control many dimmers. For dual color lights , it offers color temperature adjustment and brightness adjustment of each channel functions by touch operations. In terms of RGB/RGBW lamps, various functions can be found especially RGB color tone adjustment and dynamic changing pattern control besides dimming and switching.
The dimmer shall be designed with corresponding interface depending on the touch panel. If the panel is a RF wireless controller, the dimmer shall be designed with RF interface that receives RF signal. If the switch is a controller that sends out digital control signal reminiscent of DALI and DMX, the receiver shall be designed with DMX or DALI interface to receive the signal. Pairing is required for RF signal, and wiring is required for DMX or DALI signal. Once all done, you possibly can enjoy ultra smooth control for your property lighting.
