Today we’re going to review part number PK34212. This is the Pollak Heavy-Duty Toggle Switch. This is a custom-design, chrome-finish toggle switch. It is a single-pole, single-throw, on-off toggle switch. It is designed for high-current application, provides the longest possible service life, has an aluminum knurled face nut right here on top. On the bottom is a nickel-plated hex nut. It does use a rugged, glass-filled nylon slide.

Here’s a close-up of the Delta Engineering Model SRP1 short-run, weigh-counter filling 50 pieces of a 5/16-18 X 3/4 Hex Washer Head Cap Screw into a bag. The machine does the filling so the operator can do the closing and labeling. Being an easy to use, fast to changeover, semi-automatic system, the operator only touches product to correct the final count much like a check weighing system.
