[TheForge] Power hammer Vs air hammer

[Grover Richardson]

Yes.  A cheap switch would also be the brake light switch for a 1939 Buick.
It sees pressure when you push on the brake pedal.

Hmm.  An addition would be to have a regular light to also shine on the
hammering area.  That way the area of danger would be illuminated as an
additional notice, and as an aid to hammering.

Part numbers like this are useful for anyone who wants to copy the design.

Thanks!!

All the best.
