Supreme electrical installation with all starters housed in one case together with an isolator. Each starter carried three thermal overloads and no-volt release and were operated by push-button contactors paced  in convenient positions. The socket seen on the top of the case was used to power the mortising attachment, an accessory that came with its own motor

The Dominion saw setter was made in four sizes to suit all blades likely to be found on the company's machines. Fitted with hardened jaws, the top of the pair was fitted with a spring such that, after each tooth had been set, it sprang back into the open position.
