The invention relates to an interlock assembly for a spindle mixer where the interlock assembly includes a cup guide, an actuator pin, and an interlock mechanism. Placing a cup within the cup guide actuates the actuator pin that, in turn, engages the interlock mechanism. Engagement of the interlock mechanism selectively activates an electric motor. The pin moves through the body of the guide. The guide can be selectively removed from the mixer, and the pin, in one embodiment, is selectively removed from the guide. An optional bypass switch can be included to allow for the direct engagement of the motor.
