Durite 1-2-both battery isolatorswitch

I expect you will get responses (including from me) asking why you are thinking of buying that type of switch (of any make) when there are far better ways of wiring your batteries and providing isolation than that.
 
I love my 1-both-2 switch, I know there are a lot of people who prefer to use different ways. Personally, I'd go for a better known brand.

I don't want to be told about other ways of wiring my batteries, thank you very much. I know there are alternatives, but I just want an affordable heavy duty 1-2-both switch.

Durite is a British company registered in England and Wales, No. 373113

The Perko heavy duty battery selector switch (2.5 times more expensive) is rated 380 amps continuous, 850 amps intermittent against the Durite's 310A continuous, 500A max, but I can't imagine what onmy boat would ever draw anythng like that current, so feel that from the current rating pov the Durite is probably OK. Certainly many chandlers are selling switches with lower current ratings.

The one I have is neither of these but is badged either Eval, Vetus or Hella, maybe more. Its rating seems to be lower than the Durite you are interested in. It is used with our 2.2 litre BMC diesel engine, which can take prolonged cranking to start. No problems at all in five years. or so.

I suspect it is somewhat more highly rated than mine, and note one of the reviews here refers to good cable entry and access to terminals, and a positive feel to the mechanism - all of which I would value, having re-wired my own in an awkward spot. https://www.amazon.co.uk/Battery-Isolator-Change-Switch-Marine/dp/B00EPFHEO6

I'm not convinced that the switch in your Amazon link is actually a Durite product. It gives a different part number (1016) and merely says it's cross-referenced to the Durite part. It's a copy, most probably.

I did not notice the absence of the Durite name in red, so my apologies and thanks for that.

If it is a close copy, I guess that the reviewer's points about good cable entry and terminal access may well also be true of the Durite.

Rather than a "better known" brand, perhaps a "better quality" brand? As regular readers know, I hate 1-2-Both switches, purely because of their ability to be wrongly set and discharge the start battery. However, if I absolutely had to have one, I'd get a Blue Sea 9001 for £45 (panel or surface mount, 350A continuous, 600A max for 5 minutes - note the Durite's max rating is for 5 seconds). Or I'd get the rather better looking BEP Marine 721 for £49.

Edit: I imagine the Durite is a "make before break" design? It doesn't say. The Blue Sea and BEP switches are.

But Durite have been a respected manufacturer for years, most of the lorries and trailers have used their products since the Scots started throwing spears at the moon.

As you say probably nothing. Even a 2kw starter motor draws less than 200Amps
