Hi Andy,

What be you making now.  Trying your hand out with some electro forming
of metals.

There might be some mechanical device that could do what you want
with a switch that has a rotating member that shorts two busbars
for a portion of a revolution and sticks in the off position and tensions
a spring until it is forsed to turn past the 'on' position at a
suitable speed to achieve the required on time.

Semiconductors seem to be available in a few types from what I see on the
list.

Cheers
