Product Details
Fujisoku MRK Series Key Switches
Fuijsoku MRK series Key Switches are designed to be used in many low voltage switching applications. The single pole Fuijsoku MRK Key Switches are available in a choice of straight or right angle PCB mounting options with versions that include key trapping (key cannot be removed in one or two positions) or non-trapping (key removable in all positions). The three position Key Switches have a 45° index angle while the two position Key Switches have a 90° index angle.
All versions feature: steel ball mechanism that gives an assuring click operating feel; self cleaning contacts that provide high contact reliability; and 2.54x2.54mm (.100" x .100") terminal spacing that conforms to standard PCB grid spacing.
