S - SF series

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 specially designed for flow soldering at 260°C during 5 seconds owing to high-temperature polymer parts.
• Iron soldering (SF 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 (-20°F to 185°F)
• Storage temperature: -40°C to +85°C (-40°F to 185°F)
• 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): 4A 30VDC
- gold plated brass contacts (CD or 0): 0.4VA 20VAC or DC
- gold plated silver contacts (AD or 2): 4A 30VDC (300mA 30VDC for gold plating)
