[sdiy] Momentary Toggle Switch question

[J. Larry Hendry]

SPDT - On-None-(On)
Two positions only.  Always spring loads back to the same position.  That
position can be on or off (NO or NC) depending on wiring.

SPDT - (On)-Off-(On)
Three positions (center off) Alwasy springs back to the center from either
of the two outside position.

SPDT - On-Off-(On)
Three positions (center off) - one position springs back to center, the
other side does not spring return.

Subject: [sdiy] Momentary Toggle Switch question


I want to order some high quality momentary toggle switches so I can
finish putting together my Milton sequencer.  All I need is a simple
SPST or SPDT switch that has a voltage on one terminal that gets routed
to the other terminal when the switch is held down.

Going through Mouser's catalog, I'm a little puzzled at the different
options available.  Which of these would be the best choice for that
purpose?

SPDT - On-None-(On)
SPDT - (On)-Off-(On)
SPDT - On-Off-(On)

Thanks,

Romeo
