Easy installation
Working well. I used it to replace a faulty motor control board on an 18v Ryobi lawnmower. The harness and the length of the leads made for easy installation.

As described and good value, but....
Yes they worked fine, yes they are described, no they are not clear are to which wire connect to the main feed and the 'trigger'. The main issue I had was the short wires. I would much preferred them to have the connectors to wire up in place of having the short wires and then having to join wires to the relevant connections.

Great value for money and pre-wired ease
Great relays for the price, coming pre-wired with an optional holder made life much easier for installation too.

Ho acquistato questo set di relè per un impianto elettrico su auto e sono rimasto soddisfatto. La qualità costruttiva è buona, i cablaggi sono spessi (12AWG) e i connettori risultano solidi, non lasciano gioco una volta collegati. Il diodo integrato è un plus che protegge meglio il circuito e allunga la vita dei componenti. Li ho testati sia su auto che su una piccola imbarcazione e hanno funzionato senza problemi. Facili da installare e con etichettatura chiara dei pin, risultano adatti anche a chi non ha grandissima esperienza. 👉 Pro: cablaggi spessi e resistenti, diodo integrato, versatilità d’uso. 👉 Contro: le staffette di fissaggio potrebbero essere leggermente più robuste.
