"This precision switch is designed for use on hinged guards, with the operating shaft fixed to the hinge bolt. On opening the guard, the shaft will rotate, breaking the N\/C contacts with a positive mechanical linkage. The stainless steel shaft has a 10mm bore hole. Positive break is achieved with just 2 degrees of rotationSeries = TVS 335Lock Style = HingeNormal State Configuration = NO\/NCMaximum Current = 4 AMaximum AC Voltage = 230VMaximum DC Voltage = 24VNumber of Cable Entries = 1Size of Cable Entries = M20 x 1.5Conduit Entry = M20Shaft Length = 24mm"
