General specification

• 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 (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.

Environmental specifications

• 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).

Electrical specifications

• Max. current/voltage rating with resistive load :
- silver contacts (A or 1) : 4 A 30 VDC
- brass, gold plated contacts (CD or 0) : 0.4 VA 20 VAC or DC
- silver, gold plated contacts (AD or 2) : 4 A 30 VDC
(300 mA 30 VDC for gold plating)
• Initial contact resistance : 10 mΩ max.
• Insulation resistance : 1,000 MΩ min.
• Dielectric strength : 1,000 Vrms 50 Hz min.
