These washable miniature toggle switches with plain bushing
Specifications
Distinctive Features:
- Process sealed
- Front and rear sealing
- Process compatible
- Wave solderable
- Washable
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.
- 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 (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
- 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).
