Note about JIS/Phillips screwdrivers, screws and Special Tools.

JIS, sometimes called a "Japanese Phillips screwdriver" is very similar to a Phillips screwdriver.
The difference in a nut shell:
The difference is the walls of the slots in the JIS screw head, which are parallel and which will
cause the regular style Phillips screwdriver to cam out of the screw as you're trying to turn it.
Also, the JIS screw head slots have a shallower depth, preventing the taller head design of a
Phillips head screwdriver to properly grip the sides of the fastener.
A JIS screw is striking similarity in appearance to a Phillips screw. JIS screws are often damaged in removing
and installing because most people use a Phillips screwdriver on them.
JIS screws can (usually) be identified by a single dot, next to the screw slot or bolt head.
Toggle switches are attached with a nut that has two slotted indentations on opposite sides of the nut.
People usually used needle nose pliers to tighten or loosen this type of nut, but that can scratch and
damage the surface of the equipment and over tightening can damage the switch or ST16S.
Proper Tool is a spanner wrench to do a proper job and to prevent damage to the switch/equipment its
attached too.
