'-The lamp brightness can be adjusted by requirement,it is very to operate. -It can touch in medium protection,such glass,acrylic,plastic,ceramics and so on,which is very safe. -Wide application of voltage range,you can choose arbitrarily between 2.4V to 4.5V. -Anti power and phone interference,the EFT can reach above /-2KV;the touch response sensitivity and reliability will not affected by the close distance or multi-angle mobile phone interference. -Install: Needn’t to touch copper foil directly,the dimming can be processed across acrylic glass(above 3mm) or plastic. -Application:It can control LED module,light and so on.It is available for indoor LED,lighting lamp,DIY automotive lights dimming refit. -Function:Single touch,using the principle of capacitance touch .-The default function is switch,dimming,with brightness memories LED touch dimming.It will light slowly when turn on the lights,and become dark slowly when turn off,which effectively avoid the stimulation to eyes. -Dimming mode:Non-polar PWM dimming. -Wiring method:PCB board(VCC,GND) is power input,(LED , LED-) is connected with the LED lamps of positive and negative level (fingerprint) touch area, also can wire to lead out (the wiring should not be too long), copper skin area should be 2x3cm. With copper foil copper foil board module will side to the shell side.
