Those of you who need a rugged electronic switching relay (solid state relay) for automotive use, that can handle >55 Amps continuos, briefly up to 500A, draws less than 0.2mA and is TTL and CMOS compatible, take a look at PowerMAX. It's delivered by the australian company DTec.

Among other products, they have a thermocouple amplifier, a racer's weather station, and an article section full of useful things, like a very nice DIY flowbench design, and a DIY inertia dyno design. Those of you running EFI may also find other interesting info.

It is not listed in the payment options, but according to their links page, they use PayPal.
