Not so straightforward. Looks as though all 3 switches were latching but
now momentary. But there is electronic latching but with little or no
latency.
So if the switch contact is dirty/bounces then will electronically
de-latch, at least on the Harmony sw. Bridging the contact by hand with
a 200 ohm resistor I can make the it change latch a number of times a
second.
