i was satisfide with this product
Look good and well packed/packaged. A wiring shjeet would be useful as there appears to be no marking on the pcb so I assume that the centre is the switched output but which side is +ve and -ve will be trial and error.
Paid a few cents more for Canada Direct Mail shipment and items arrived in just 11 days. Items arrived in great shape and don't expect any problem with them, but won't get a chance to actually try them out for a few days.
Perfect. However at first view I thought it's work as a simple switch, but it needs extra circuit elements.
nice
