CAD Data
■ Fastening of the switch body
1) In fastening the switch body, use the
M1.4 screw (3 types ... screw head
diameter from 2.4 dia. to 2.6 dia.), with
tightening torque of not more than 0.098
N·m.
2) In setting the movement after
operation, the over-travel should be set
within the range of the minimum OT
value. Please set up so that a operation
object does not apply force to the switch
body.
■ Environment
Avoid using and storing these switches in
a location where they will be exposed to
corrosive gases, silicon, or high dust
levels, all of which can have an adverse
effect on the contacts.
■ Soldering
1) Manual soldering should be
accomplished within 5 seconds with max.
320°C iron. Care should be taken not to
apply force to the terminals during
soldering.
2) Terminal portion must not be moved
within 1 minute after soldering. Also no
tensile strength of lead wires should be
applied to the terminals.
3) When using the angle terminal type,
insert an insulation separator between
the switch body and the PC board
(Insulation separator 0.2 to 0.4mm thick)
to prevent the soldering flux from flowing
under the PC board.
■ Cleaning
As AV4 (FU) switch is not completely
sealed construction, avoid cleaning.
■ Selection of switch
Please make your selection so that there
will be no problems even if the operating
characteristics vary up to ±20% from the
standard values.
■ When switching low-level circuits
(max. 100 mA), Au plated contact
types are recommended.
