Power supply circuit for spot lamp switch

Power supply circuit for spot lamp switch

Answer:

Is the main capacitor, you can calculate the total work left in 15 equal to the capacitance current of the capacitor (uF), on can in AC circuit bridge rectifier before, remember on a capacitor and a resistor 470K
That is to change the circuit, more trouble, it is better to do their own capacitor step-down circuit, simple and affordable
Yes, 35W spotlight switch, the power supply voltage is how much, greater than 24V on the line, equal to 24V better, direct power up.
