Abstract

Improvements in speed regulation devices for portable electric tools or similar apparatus, characterized in that each device is provided with: a housing adapted to be mounted inside said motorized tools or similar apparatus; means within said casing that define a speed regulation circuit provided for a rheostat, whereby the speed of the associated motor can be varied in response to changes in the resistance of said rheostat; a speed control element operable by hand, mounted on said casing and coupled with the element of said rheostat to move it in response to the movement of said element; on-off switch contacts comprising a moving contact associated with said circuit for opening and closing it; and a connection-disconnection control element, operable by hand, movably mounted in said casing, adjacent to and independently of said speed control element, said connection-disconnection control element coupling with said mobile contact to operate said on-off contacts in response to movement of said on-off control element.
