Number of cycles
2 positions
3 positions
SEALING
Internally sealed bushing
Epoxy sealed terminals
Secure assembly of the two
case parts
MECHANICAL STRENGTH
Terminals are strengthened by a
bracket or a ground plate
ensuring the rigidity of the switch
on the board.
Actuator strength is 10N max.
SOLDERING THERMAL SHOCK
The switch is especially designed
for flow soldering at 260°C
during 5 seconds owing to high
temperature polymer parts.
SOLDERABILITY
The switches are tested at 235°C
according to IEC 68-2-20 after
accelerated aging.
AGENCY APPROVALS
Availability
: consult factory for details of approved models.
Marking
: to order switches marked UL, complete appropriate box of
ordering format.
MOISTURE
The insulating materials
employed and the complete seal
permit the switch to withstand a
56 days moisture test
(IEC 68-2-3).
Distinctive features and compatible
wave soldering processes : see
specifications S and SF, section B.
