Snap Switches –
De?nitions and descriptions
Snap switches are activated by a
spring-operated (or “snap-action“)
mechanism. Depressing the actuator
triggers the switching operation, with
Actuator
Applying force to the actuator of a snap switch releases the snap-action
mechanism, which in turn triggers the switching operation.
Auxiliary actuator
It is possible to attach an auxiliary actuator to a snap switch in order to
meet the speci?c requirements of a given application. Doing so usually
alters the travel and forces involved in the switching operation, depending
on the length of the levers. By attaching an appropriate auxiliary actuator,
it is possible to increase travel and/or reduce the actuating force required.
a pre-de?ned force and travel. The
Terminals
switching speed itself is largely inde-

is, the terminal is connected to COM. When
the switch is actuated, the contact opens.
NO (Normally Open = 4): The contact is open in the rest position, that
is, the terminal is separated from COM. When
the switch is actuated, the contact closes.
Contact gap
(contact opening distance)
The contact gap is the distance between a pair of open contacts. For snap
switches, it is usually around 0.3 mm. Generally speaking, for switches
with contact gaps < 3 mm, additional measures are
necessary for separation from the mains. These switches bear the mark μ
for European approvals. Switches with a contact gap > 3 mm can general-
ly be used directly for separation from the mains. Please check the device
speci?cations applying to your particular product, and if there is any doubt,
please clarify with the responsible testing agencies.
Clearance
and creepage distance
Clearance is the shortest distance through the air between two electrically
conductive parts or between an electrically conductive part and a metal foil
af?xed to an accessible surface of some insulating material. The creepage
distance is the shortest distance along the surface of an isolating material
between two electrically conductive parts or between an electrically con-
ductive part and a metal foil ?xed to an accessible surface of the insulating
material.
