ABSTRACT:
An improved ordnance arming knob assembly. An arbor is secured to a switch shaft. A knob is keyed to the arbor to move in an axial direction relative to the arbor while preventing rotation between the knob and the arbor. A pin on the knob extends in a direction parallel to the switch shaft axis into a stationary hole located, for example, on a panel on which the switch is mounted. The knob must be pulled in an axial direction against the force of one or more springs to withdraw the pin from the hole prior to turning to actuate the arming switch.
