FEATURES OF LE TOUCH SWITCH 3.1 Operating voltage recommended 3.5~5.5 V(C) 3.2 uilt-in regulator for touch sensor (2.0V) 3.3 The response time max about 3.4 Sampling length time about 1.6mS. 3.5 Provides direct mode or toggle mode by pad option. 3.6 Output modes can be selected active high or active low by pad option. 3.7 the surface can display in two different designs: 1. symbol display in the middle by RG LE 2. outer circle background controlled by single chip of LE; the LE is independent installed and both can be reacted by external chips. 3.8 Auto calibration for life, the re-calibration period is about 4.0sec, when key has not be touched. 4.

If the supply voltage drift or shift quickly, maybe causing false detections The material of panel covering on the Switch can not include the metal or the electric element At irect mode: IC Maximum on time about 80 Sec. 12.
