ABSTRACT:
A blender (13) comprises a base support (12) having a motor (14), a container (22) formed in two connectable and disconnectable portions (23, 26), a first of the portions being a base portion (23) mounting a number of rotatable blades (30) and being connectable to the base support so that the blades will be driven by the motor (14), and the other portion comprising an upper open tubular portion (26), the blender including a motor disable switch (17) arranged to automatically disable the motor unless the base portion and upper portion are fully engaged with each other and the base support. A switch operating member, in the form of a collar (41) and plunger (20), provides effective connection between the upper tubular portion (26) of the container and the switch, such that it will move the switch to its operative position when the upper portion and base portion are full engaged with each other and the base support.
