Hazard-Switch Nut Wrench

Open-sided wrench for removing and installing the plastic retaining nut around the hazard switch without plier damage. The creator physically demonstrates the wrench with the switch and recommends the stiffest suitable material because the clearance slot permits some flex. The title's 61311356193 identifies an early complete hazard switch, not the printed tool or its nut, so it is not assigned as an OEM number. Switch design varies by production date; use only light hand torque on the plastic nut and confirm jaw fit before turning.
