S series


New product

These washable miniature toggle switches with plain bushing  are specially designed for flow soldering at 260°C during 5 seconds owing to high-temperature polymer parts.

Main features

  • Secure assembly of the two case parts
  • Internally sealed bushing
  • Epoxy sealed terminals
  • Process compatible: Wave solderable and washable
  • Optional ESD protection

    A cap U3012 provide additional protection during PCB processing, supplied mounted on the switch or separately. Material: vinyl.

    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 10 N max.
    • Soldering - thermal shock : The switches are especially designed for flow soldering at 260 °C (500 °F) during 5 seconds owing to high temperature polymer parts.

    Environmental specifications

    • Operating temperature : -20 °C to +85 °C (-4 °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).
    • Solderability : The switches are tested at 235 °C ( 455 °F) according to IEC 68-2-20 after accelerated aging.
