Latching / Non-Latching Switch
-
From Wikipedia, the free encyclopedia. A latching
switch is
a switch that
maintains its state after being activated. A push-to-make,
push-to-break switch would
therefore be a latching
switch –
each time you actuate it, whichever state the switch is
left in will persist until the switch is
actuated again
-
Conversely, a non-latching relay
maintains its state only while being actuated. ... Anon-latching electromechanical
relay is useful in control applications when the
switch must
return to a known state if power is lost. It is often used in push
button applications such as keyboards or microcontroller input
buttons
