A "Push to make" switch is only in the "On" position when it's pushed in and
held in. Commonly used as door bell buttons and the like.

A "Momentary Action" switch is when the switch will latch (lock) in the "On"
position for a second or two by itself before releasing to the "Off"
position again, or vice versa. Commonly used where a need for a long signal
to start a series of relay contacts need to be established, or as a short
timer for pass through lighting systems.
