A snap action switch requires very little mechanical
movement (a very short linear distance) in order to actuate
the electrical switch contacts. Internally, the movement
and mechanical advantage of a lever is used to activate,
make or break, switch contacts.
The sensor elements in pressure switches: diaphragms,
pistons, bellows, all have move relatively small distances
with changes in pressure. A snap action switch is used as
the electrical component in a pressure switch because it can
be actuated/tripped by the small movement of pressure switch
sensor.
Mechanical adjustments allow for an adjustable setpoint by
moving the snap action switch with respect to the sensor
element.
The name of the firm that invented snap action switches is
Microswitch, so snap switches are frequently called
microswitches, which is technically a brand name.
In contrast, ordinary switches, like a toggle switch or a
rotary switch, rely on the relatively large movement of an
operator handle/lever to actuate the electrical contacts.
