BOSCH 0332019110 Normal Open Mini Relay - 4 Pins, 12 V, 30 A - Single

This Bosch relay is great quality and compact in size which is helpful using it to create automotive auxiliary circuits as I needed to do. Used one to create a 20 amp ignition switched circuit for a mobile GMRS radio and it has been working great. I had not doubts about the function or quality since these Bosch relays are commonly used by OEM's in their factory wiring.

I had an issue with a lawn tractor not wanting to start. It's a common issue where all the safety switches over time contribute to a voltage drop by the time the signal makes it to the starter. Instead of troubleshooting the existing wiring and all of the switches (could be very time consuming and costly)... I opted to wire in this relay switch that pulls the current directly from the battery. All of the safety switches still work and the tractor starts every time now, and there's no more delay or failure to start. It actually starts quicker than it did when brand new (there was always a significant delay). I'm aware that if this relay were to ever malfunction, the tractor could bypass the safety switches and start when it shouldn't, but I follow good procedures anyway so it's a non-issue.

Fits like the original! .. works like a charm .. no more issues with not having my glow plugs light up!

This works great in my TC 40 new Holland tractor. My glow plug light quit working,making it hard to crank in cold weather. Installed this relay and had it going in no time. Would buy again and well worth the money.

Great item

Great to use in motorcycle & other circuit where you want to let small current control heavy (high amp) currents such as starter motors.

Works perfectly, great material. Bosch is a good name brand so I’m not surprised! Hope it stays this price !

I bought this relay as an exact replacement for my push mower. It was also the cheapest one surprisingly. Fit like a glove and restored my mowers electric start back to when it was new in 1994(lol)

Buon prodotto

Die Hupe eines Traktors sollte über ein Hitzerelais geschaltet werden. Der vorhandene Strom reichte für die Hupe nicht aus. Dank Relais funktioniert nun alles wie es soll.

Degelijk autorelais van een degelijke fabrikant Bosch. Met interne blusdiode tegen piekstromen, perfect. Niet twijfelen, als je zo'n type relais zoekt, deze kopen.

Je m'en suis servi pour remplacer un qui avait cramé dans mon camping car pour le frigo je suis parti en vacances et mon frigo a très bien marché en 12 volt. Je les reçu deux jours après pas besoin de perdre du temps à courir après la débauche merci Amazon.

Muy bien cumple como el original.
