Rope-pull safety switch
IP67, 250 - 400 VAC, 10 A | SiRK, Si1, Si2
BERNSTEIN AG
The switches are available in two metal versions, the Si1 and Si2, as well as an insulation-enclosed version, the SiRK.
These types of cable pull switch are ideally suited for applications with high temperature fluctuations and long cable spans. With their sturdy enclosure, the Si1 and Si2 are the perfect switches for harsh environments.
Two cables spanned in opposite directions are attached to the switching device. The countersprings are secured to the wall at the ends of the cables. Provided the change in temperature is the same at all points along the cable, the springs will effectively compensate for the change in cable length.
