ABSTRACT:
A switch and connector for selectively creating an electrical circuit between a motor mounted in a power foot and a combination vacuum cleaning/water extraction machine is disclosed. The motor mounted in the power foot drives an agitation member rotatively mounted in the power foot. The power foot is inter-connected to the housing of the machine through a rigid wand, a grip tube and a flexible hose. A pneumatic switch is mounted in the electrical circuit between the source of electricity and the power foot motor. A bladder is mounted to the grip tube and in fluid communication with the pneumatic switch through a conduit. The bladder is constructed such that the pneumatic switch cannot be activated to create a complete electrical circuit between the source of electricity and the power foot motor unless the grip tube and wand are properly assembled.
