SMK J-M0404 alternate action or SMK lock is a vintage mechanical lock switch in the SMK J-M0404 series. The keystem can be either vertical, or angled.<ref name="DT-Angled" /> The latching mechanism is enclosed in a containing block that slides into place along slots in the shell; a sprung, turned brass follower in this enclosure engages in a track in the slider.
The switch has "SMK" embossed on the bottom, either in the older SMK diamond logo (below), or the newer logo without the diamond.
No NEC or Maxi Switch variants have been encountered thus far.
