Probe domestic switch needle KG-300K needle head diameter is 3.0mm normally open switch needle
100V, 250mA, surface mount, high speed switching diode
MOS power IC full range
SMD aluminum electrolytic capacitor
L: Connect 220v AC line
N: Connect 220v AC neutral line
FG: pick up the earth
G: DC output ground
+5v: output port with +5V point
ADJ: The output voltage is adjusted within a certain range. The rated voltage output on the switching power supply is originally fixed at the factory, that is, the nominal rated output voltage. Setting this potentiometer allows the user to use a smaller one according to the actual use. Adjust the output voltage within the range. Under normal circumstances, it is not necessary to adjust it.
