mechanical characteristics
snap-action switching element
switching system
The double-break, snap-action switching element is equipped with
one or two independent contact systems, acting as normally open
or normally closed contact.
The snap-action switching element is fitted with self-cleaning con-
tacts.
Up to 3 switching elements can be snapped to each actuator.
material of contacts
hardsilver, gold/silver, silver/palladium (for aggressive atmosphe-
res)

connection method
screw terminals
plug-in terminals 6.3 x 0.8 mm:
max. wire cross-section: 2 x 2.5 mm&
max. wire cross-section of stranded cable: 2 x 1.5 mm&.
For switches with plug-in terminals it is necessary to provide insu-
lation sockets and to maintain a spacing of 65 mm between rows
(mounting dimensions).
