welcome to diydegss , you could order the items for home , ckichen tool , stroage ,decorations and so on Features:
Safer design with protective case, suitablefor home and factory use.
Using original imported 41A SCR.
Using 1.6 mm FR-4 PCB, reliable and safe weldingdesign.
Upgraded double capacitance circuit design (safecapacitance and metal film capacitance) protects the SCR by reducing surge andvoltage spike. Brings more safety and efficiency.
