Hard-drawn Copper blades, formed into a trussed "A" frame shape for rigidity and maintenance of proper alignment, provide the strength that makes Turner Hookstick switches perfect for demanding Substation applications.
All blades latch into position for positive locking. Blade stops are provided at 90º, 105º and 135º openings. Standard factory setting is 90º. Standard switches come with 2.5" or 3" B.C. station post insulators.
