The designer has requested anonymity.... only retail outlet that agreed to carry them was Luna....
I have one, and it is a good product. I paid full retail for it.
Lol. Sure.. Invented by... Flipsky.. Or at least here is the Flip sky one that has been around forever and can handle like 280/800A... not the wimpandcheapasf Luna offering.
Amain has them. Always had. Alien power systems have them.

Here is the Alien one.. SAME EXACT PCB but BETTER RATINGS withGOOD COmponants... Rated for 2x the current and power. Luna is only ( lol ) 120A PeAk.... Plus the Lunashit is always unavailable. Lol. What a surprise, they will come out wit a "better one" and talk up them "ratings"...
See a Luna pattern ? Emerging? Old tech talked up and sold for more than it is worth? lol.... Lemme pay 99.95$ for that INFINEON clone 60a controller again...

Its an old switch, from my experiences. I have seen one with the exact same sticker. Same PCB, low ratings... on the luna.
Another.

Same exact look.
Another. Same exact PCB... I guess your friend who invented it is getting rich from the royalties?

No offense to you, SM.... Just your place to purchase is always the most jazzed up with ratings and prices that can be easily beat. I believe you have some proprietary design info like a choice of populated components 0r something, but I dont think it was made specifically for the Luna, when Flipsky has been selling the same thing but with a 300A/800A rating. They are cheap, and they fail straight closed. Dont hate me for being the Devils Advocate. I believe there is a list of options the ( chinese) manufacturer offers to the ( business that sells to) consumers with options for population and certain design aspects, but the contracting company still just picks the stuff off a list, chooses how many to buy, marks up, and then caters to the individual buyers..
Another: Same exact PCB, but this one is doubled pcb for more power and Voltage handling... Emcotech is good stuff.... You know, for when you are flying your 3-5000$ RC jet that only allows ONE mistake... Double redundancy...

Not trying to knock your idea, S. Magnets. Only and just the idea that the LUna switch is the best or the one that was first, or proprietary in some way ( I would love to see concrete evidence of this)... Show me the concrete and I will stand on it as you do. It is a RC switch from what I have experienced. Commonly availible from the world of RC for ages now. My best heli cost 3000$ and that is real brand new money. I have been doing the RC thing for many years now, as long as you and the Ebikes. We all strive. My heli is reliable as i could make it. They kill in an instant .. so they have to be.
You would think they ( Luna) would have designed their own sticker to go under the clear heatshrink... Not to much more ( cost in) setup in a production run ( of a number of products) to implement such a thing? A sticker, printed from a graphic, on a computor, that you will be printing anyway?... The Flipsky one is even in a hardcase. Lol.
You said above that I have not used them ( that design.. that pcb, with that red and black silicone wire, and that shiny remote mounted switch, same length of wire and same look: carried by many other online retailers... ). I have. They failed.
People, please knock my ideas freely. Honestly, using a 30v rates switch for a 48v system should not be to much a problem, a 120/240v AC breaker will still break at rated current on DC of half the voltage at load, and a precharge will stop eroding of contacts if implemented correctly. You can double up two DC DIN power breakers for 2x rated current. ( 2x30A DC DIN) = 1x60A DC DIN). Understand zero crossing, amplitude, magnetic flux, power and load as you will.
If you want to buy cheap common Solidstate RC switches, do as you wish.
Lotta Wh in our application vs hobby rc application ( where the batteries are put away after flyig for the day.. NOT left hooked up FOREVER and wheeled INSIDE to charge .. permanently mounted... on vehicles... that shake and go through rain and mud and snow... ( unattended) (in your home, where the children play)( and sleep).
Any Ev system should have a fuse, a breaker, and an emergency/maintenance disconnect. All three, IMo, if it has any significant power or energy stored. I bet you will knock me for using "12v rated" audio fuses, on 90v.. too. Even when some have sworn by them on the forum. Sound like a pistol when the go and they go fast. I have alot of (laymans) experience with power in industry and what is commonly used and the redundancies surrounding them.
