PUSH ON OFF LOCKING SWITCHING CIRCUIT 5-15VDC 10A OUT - READ MORE
I BUILT THIS CIRCUIT FOR A PROJECT I WAS WORKING ON.
I NO LONGER NEED IT. IT HAS BEEN TESTED AND WORKS GREAT.
YOU CAN INPUT 5-15VDC IN ON THE + AND - TERMINAL. PLEASE NOTE
THE CIRCUIT WILL LOCK ON WHEN THE MOMENTARY BUTTON IS PUSHED
AND LOCK OFF WHEN THE BUTTON IS PUSHED AGAIN. THE OUTPUT
GENERATED AT THE "OUT" POSITION WILL BE ROUGHLY 1/2 OF THE INPUT VOLTAGE.
THE IGBT DRIVING THE OUTPUT IS CAPABLE OF PROVIDING OUTPUTS OF
UP TO 10 AMPS ACCORDING TO THE SPEC SHEET. THE ONLY LIMITATION
MAY BE THE BOARD. I PROBABLY WOULDN'T RUN MORE THAN AN AMP OR TWO THROUGH
THIS BOARD. YOU CAN USE THE GROUND (-) AND THE "OUT" CONTACT TO DRIVE YOUR CIRCUIT.
PLEASE BE CAUTIOUS. THERE ISN'T ANY INTERNAL RESISTANCE BETWEEN THE "OUT" AND GROUND,
SO MAKE SURE THE CIRCUIT YOU ARE POWERING IS PROTECTED.
I HAVE INCLUDED AN LED AND RESISTOR SO YOU CAN SEE HOW IT WORKS. THE LED
WILL WORK GREAT AT 12V TO 15V, BUT IT YOU ARE RUNNING IN 6V OR LESS IT
WILL NOT LIGHT UP WITHOUR MODIFING THE SERIES RESISTOR ( IN SERIES WITH THE LED).
IF YOU DO NOT NEED HIGH POWER OUTPUT, YOU CAN SPLICE POWER OFF THE 3.7K OHM IGBT
GATE DRIVER INPUT. VOLTAGE OUTPUT HERE WILL BE THE SAME AS THE VOLTAGE INPUT (5-15 VOLT RANGE).
I CAN GARENTEE THE CIRCUIT WORKS, BUT I WILL NOT RESPONSIBLE IF
YOU BLOW IT UP OR BLOW OTHER CIRCUITS UP WITH IT. USE AT YOUR OWN RISK. I CAN BUILD MORE OF THESE UPON
REQUEST, BUT IT MAY TAKE TIME.
