For a project I'm working on I've located and sourced some reed switches that can handle switching larger currents and are still in a small package. The switches I'm looking at are the COMUS MH5 reed switch, which is 11mm long and can handle a 2A switching current at 25V. They're rated for 50W.
Anyhow I thought this would simplify the design of some of the circuits in lights that people often build by eliminating the need for a FET ckt used in conjuction with a reed that can only handle small currents.
The only problem is if I order them I have to order at least 10 at a price of $6.50 each + S&H and just wanted to see if there would be any interest in them as I don't need 10 and could pass off the extras.
I've attached a spec sheet so people can see exactly what they are and their ratings.
This could be used to power something like a P7 in a situation where you have say 2 18650's w/ about a 1.5A input current to the driver which could regulate the LED current to 2.8A at about 3.75V (example of J forward voltage bin). Since the switch would never see the full 2.8A as that would be through the LED it would operate just fine switching the 1.5A input current.
Other combinations of supply voltage and input currents would work with other drivers too as long as it doesn't draw more than 2A of input current, exceed 50W of power or 500V of supply voltage (not likely to exceed 50W or 500V in a dive light).
Anyhow just a probe to see if there is interest, I'm probably going to purchase them regardless for my project but don't really have any need for 10 of them, maybe 3 I'll keep.
