Abstract:
1. A hand-held controller which comprises: a cup-shaped housing, a circuit board mounted in the housing, at least a pair of activation switches comprising first and second activation switches mounted on the circuit board, a separate electrical circuit connecting the activation switches of said pair of activation switches wherein opening and closing of said first activation switch of said pair of activation switches, when activated, is configured to communicate a first function and opening and closing of the second activation switch of said pair of activation switches, when activated, is configured to communicate a second function that is different from and independent of said first function, and a separate controller means for completing or interrupting said separate electrical circuit and thereby activating or deactivating said pair of activation switches in the associated electrical circuit, each controller means comprising an on-off switch connected in the respective electrical circuit and a separate rotatable knob for operating each on-off switch, wherein said on-off switch is arranged relative to said pair of activation switches such that when said on-off switch is positioned to complete said separate electrical circuit the opening and closing of the first activation switch of said pair of activation switches communicates said first function and the opening and closing of the second activation switch of said pair of activation switches communicates said second function, and wherein each of the on-off switches has an axially movable activation element and each knob is rotatable about its axis and has a knot with a surface that rotates when said knob rotates, and wherein when the knob is rotated, said surface of said knot engages said activation element of said on-off switch depressing said activation element axially inwardly to activate the on-off switch for cutting off the circuit for the activation switch.
