EOS To M42 Auto Adapter HELP

Just bought a Vivitar 300 TX that has the M42 mount but goes not have the Auto/MF switch so with my existing EOS to M42 adapter I can only use it wide open.
Anyone know of an adapter that will depress the button so that I can use it in Stop Down metering mode

Hi Captan,

See photo of two different M42->EF mount adapters>

The left one has a ledge which pushes aperture pin of M42 lens,
you should get this type of adapter. I got that black one from
ebay seller ROXSEN in Japan, a reliable seller and long time telescope
and camera accessary seller originally and now too.

note: This type adapter sometime causes a problem for m42-lens which
has a bigger rear block, this prevents from inserting the lens in the final
resting position. In this case you may not be able to focus infinity.

The right side M42->EF adapter was from ROXSEN or HappypageHK.
