Title:
WINDOW SWITCH IN VEHICLE WITH LEAKAGE CURRENT PREVENTION MEANS
Document Type and Number:
WIPO Patent Application WO/2012/015142
Kind Code:
A1
Abstract:
The present invention relates to a vehicle window switch for turning-on and turning-off of an electrical signal input to a micro controller for controlling opening/closing of a vehicle window, the window switch characterized by: a manipulation switch; a leakage current prevention means applying or interrupting an electrical signal to the micro controller as the manipulation switch is closed or opened; a first resistor connected in series between the manipulation switch and a power source terminal; a second resistor connected in series between the power source terminal and the leakage current prevention means; and a third resistor connected in series between the leakage current prevention means and ground. The present invention disposed with the leakage current prevention means can prevent an excessive current from flowing in a micro controller to prolong life of the micro controller and to enhance reliability of the micro controller.
