I have a Fuji camera with a selector switch problem that I could probably fix IF I could take the unit apart. However, I do not have a screwdriver to fix a triple slot screw and can not find what the screwdriver is called to search where to order one (called electronix store and they had no idea what I was talking about). The screw head is a normal circle with a perfectly even 'Y' in it. Anyone know what it is called? Thanks
