A control mechanism is provided for coupling/interrupting two transmission leads. A first cam configured for spring-loaded rotation in a direction of rotation is positioned between the two leads. A lead coupler attached to the first cam couples the two leads to one another when the first cam achieves a prescribed position. A second cam is disposed adjacent to the first cam for, in sequential fashion, i) maintaining the first cam in a first position different than the prescribed position prior to rotation of the second cam, ii) permitting the spring-loaded rotation of the first cam from the first position to the prescribed position after rotation of the second cam commences, iii) inhibiting the spring-loaded rotation of the first cam from the prescribed position for a prescribed period of time during continued rotation of the second cam, and iv) permitting the spring-loaded rotation of the first cam from the prescribed position during continued rotation of the second cam after completion of the prescribed period of time.
