Patent number: 4329757Abstract: There is disclosed a suction cleaner having a motor, a body portion housing the motor, and interengageable attachments adapted to be attached to the body portion for cleaning operations requiring different motor speeds. A safety switch is provided within a headlight shroud. Attaching elements are provided on each attachment so that the attachment may be affixed to the body portion of the cleaner. The attaching members are covered by the headlight shroud and are exposed by the shroud when the shroud is pivoted to an open position. The safety switch has a first switch position which disconnects the motor from an electrical circuit and a second switch position which causes the motor to run at a relatively slow speed and a third switch position which causes the motor to run at a relatively high speed. Each attachment is provided with a pin which actuates the safety switch to run at either a high speed for off-the-floor cleaning operations or a low speed for on-the-floor cleaning operations.Type: GrantFiled: November 21, 1980Date of Patent: May 18, 1982Assignee: The Scott & Fetzer CompanyInventors: Lee W.
