Abstract
A control switch is disclosed for a two-speed vacuum cleaner motor and the like. The switch provides three sensors which operate in response to the mounting of three different types of accessories on a vacuum cleaner. One sensor causes low motor speed operation when an accessory is mounted requiring low speed operation. Another sensor operates to provide high speed motor operation when a high speed accessory is mounted. The third sensor prevents motor operation when an accessory is not mounted on the outlet of the vacuum cleaner. The control switch provides a high speed/low speed switch and a power switch. The power switch is automatically moved to its open or OFF position in response to the mounting of an accessory. Copnsequently, the high speed/low speed switch cannot operate to start the motor, and is therefore provided with low cost contacts. The control switch and motor provide plug-type connectors which automatically connect the internal motor wiring when the switch is installed.
