Technical description of the push button
switches, series FK 310, FK
320, FK 610, FK 620, FK 630, FK 810
Function: The
functions of the series FK… two pole push
button switches are the operation
of the garden
machine and apparatus, electrical machine and similar
characteristic appliances.
Protection against electric shock: Suitable for class II appliances.
Mounting: The switch shall be secured in an
appropiate place within the enclosure
of appliance designed by the
appliance manufacturer where the protection
against electric shock is ensured by the parts
of the enclosure.
Protection: min. IP 40 after mounting.
Type versions:
FK 310: without push-bar, for load
3 A, four srewless terminals
FK 320: without push-bar for load
3 A, two srewless
terminals and two srew type
terminals
FK
610: small black push-bar (11 x 20 mm), two srewless terminals and two srew
type terminals
FK
620: small orange push-bar (11 x 20 mm),
for load 3 A, two srewless
terminals and two srew type
terminals
FK
630: big, orange push-bar, for load 6 A,
two srewless terminals and two
srew type terminals
FK 810: without push-bar, for load
8 A,4 pcs terminals with springy clamp
Operation mode:
The switches in normal state
are OFF. When pressing the button,
the contacts are closed according
to the ON-state
and after release the switch
automatically returns to the rest position
(OFF state).

Electrical connections: The FK 310 and
FK 810 type switches have 4 terminals with screwless terminals, the FK 320, FK610, FK 620 and
FK 630 type switches have 2 srew type
terminals and 2 screwless terminals.
Flexible conductors can only be connected to the screwless
terminals by using conductor end sleeves. The connections can be established by inserting the conductors
into a min. 8 mm deep hole on the
side of the
switch. After connecting the springclamping will be self-locking. The disconnection of conductors is possible by lifting the clamping spring with a tool (e.g.: srewdriver with max. 3 mm blade) throught the openings on
the lower cover plate of
the switch. The srewless terminals are suitable to
connect two conductors per terminals. The srew type terminals
are suitable for one conductor
per terminal without special preparation.
The connection
of the conductors
to the switch
is to be made before placing the swith into
the appliance and the disconnection
is possible when the switch is removed.
