Polyester LED Metal Dome Membrane Switch, Membrane Switch Keyboard he metal dome switches and snap dome are sure to be the switch
button. If the various switches are separated from the Metal Domes,
it loses its meaning, so it is said that the Metal Domes plays a
key role in the switch, and it was later known as the metal dome
switches and snap dome. Application of a metal dome: used on button switches, membrane
switches, tact keypads, self-locking switches, metal dome switches,
and snap dome. Function of metal dome switches: to power on and off, which can
give the operator good tactile feedback. Originally, there is no professional name called snap dome in the
early days. And a snap dome is made of metal material. Because it
is a dome, it can bounce upward and be concave downward (convex and
concave). Its initial state is convex upward, and it will concave
downward when the operator exerts a force, and then rebounds after
the force is removed. This kind of elastic metal material is
uniformly called metal dome or snap dome. Later, when metal dome
switches were introduced into China, many people were used to
calling them metal dome switches. Metal domes also referred to as
metal snap domes or tactile metal domes
