- brass, gold plated contacts (CD or 0) : 0,4VA 20VAC or DC
- silver, gold plated contacts (AD or 2) : 2A 250VAC - 5A 125VAC - 4A 30VDC
(300mA 30VDC for gold plating)
Initial contact resistance : 10 m max.
Insulation resistance : 1.000 M min.
Dielectric strength : 1.000 Vrms 50 Hz min.
Electrical life with nominal load :
GENERAL SPECIFICATIONS
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 (S series only) :
The switches are especially designed for flow soldering at 260°C during
5 seconds owing to high temperature polymer parts.
Iron soldering (SR series) : 300°C 5 sec. max.
Solderability : The switches are tested at 235°C according to IEC 68-2-20
after accelerated aging.
