Nikon F100 35mm SLR Film Body Only. All Working But Has On/off Switch Issue

Nikon F100 35mm SLR Film Body. Tested and it appears to be in full working order apart from the on / switch that is behaving oddly. The switch needs to be turned all the way to ‘illumination’ to switch the camera on and it will not fully turn off when switched back to the off position. All other functions appear to work well but it has not been film tested and I’m selling as not working / spares or repair.
