    I am in need of a remote control switch for a project I am working on. The only major criteria being that the switching component itself be physically small.
    I bought this item and it seems to work great:
    http://www.ebay.com/itm/121961150278?_trksid=p2057872.m2749.l2649&ssPageName=STRK:MEBIDX:IT

    The remote is nice, and the receiver is 6mm at its widest dimension.
    This 6mm may potentially be too big for my design.
    Does anyone know of the existence of a similar commercial device with smaller dimensions?

    No. Didn't you read the post on eBay? This one is both micro AND mini sized. About 10 years ago, the government experimented with Devices that were the trifecta: nano, micro AND mini but they were so small they disappeared. I'm sorry, @airplane100000 , You'll have to settle for this one.

    I can't accept it. I won't accept it.
    There must be as we speak some obscure Taiwanese manufacturer mass producing 5mm nano switches by the millions just searching for someone who won't settle for 6mm.

    That thing is 6mm at its tallest, not widest.

    The tallest portion of the receiver by a wide margin is the metal encased component seen in the picture. It appears to be a clock. If I were to attempt to grind a mm off of the metal case with a Dremel would it still function? Or would that be bad...

    That is the crystal. Removing the top of the can will save maybe one whole mm, but not more. And, it will expose the crystal to atmospheric contaminants. One spec of dust and the frequency will shift.

    Interesting to see if the remote would still toggle the switch though. I'm prepared to invest $8 and 1 month shipping from Hong Kong to find out.

    I have my doubts. Being the cutting tht top off is more than likely going to both destroy the crystal and contaminate the heck out of the inside of what's left of it shielding box.

    What do you need such a small receiver for anyways? How big is the power source and how big is the load?

    Moving the xtal position might be easier.

    So I can control small stuff. What I had in mind would have a small power source and a big load.
    Possibly, if i could take it off the board that would reduce a mm.

    If the X-Tal frequency is 9.81563 MHz, it can almost certainly be replaced to an SMD version, as this Abracon ABM7 series, found on the Mouser website.

    Somehow, I already knew I would regret asking the question being I had every expectation that I would get an answer that was of zero relevance or use. :(

    My expectations were met.
