Final answer:
The statement regarding routers, planers, laminate trimmers, sheers, and jig saws having positive 'on-off' control is true, but high-voltage wires being wrapped in insulating material is false; they are carried by insulators but the wires themselves are bare.
Step-by-step explanation:

The statement that routers, planers, laminate trimmers, sheers, and jig saws may be equipped with positive "on-off" control is true. These power tools often include a feature where the 'on' position is maintained until the user actively disengages it to the 'off' position; this is a safety feature. Nonetheless, the high-voltage wires that you see on metal-frame towers are not wrapped in an insulating material; they are actually bare wires supported by insulators, making the assertion false.
