GENERAL SPECIFICATIONS
AGENCY APPROVAL
• Torque : 0,25 Nm (.18 Ft.lb) applied to nut (threaded bushing)
• Total travel : 0,50 mm (.019)
• 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.
• Operating temperature : -20°C to +85°C
• Storage temperature : -40°C to +85°C
• Moisture :
The insulating materials employed and the complete seal permit the
switches to withstand a 56 days moisture test (IEC 68-2-3).
• Soldering - thermal shock (plain bushing models only) :
The switches are especially designed for flow soldering at 260°C during
5 seconds owing to high temperature polymer parts.
• Iron soldering (threaded bushing models) : 300°C max., 5 seconds max.
• Solderability : The switches are tested at 235°C according to IEC 68-2-20
after accelerated aging.
Availability
: all models with silver
or gold plated silver contacts.
Marking
: to order switches marked
UL , complete appropriate box of
ordering format.
