A control housing body (10) containing a cavity (12) of sufficient size to allow entry and movement by a human thumb, and capable of housing a number of controls (14, 16). Body (10) is inserted under a covering grip (33) that is connected in line with a surface grip (32) of a rotating steering device (31). Dial control (14) is provided to set a scalar variable such as vehicular speed at a constant number. A thumb rest (13) and a control guard (17) inhibit the thumb from slipping downwards and unintentionally activating a contracting control (16) that can be actuated by the contracting movement of a human thumb. A sliding cover (40) can be alternately positioned over cavity (12) or inside retraction slot (46). A pivoting pin (22) and pivoting rotator (24) allow the control housing body to rotate around the axis between two pivot holes (26) and (28). Signal-conducting wires (35) pass through rotator (24), through right pivot hole (28) and then through surface grip (32), spoke (34), and steering column (36), transmitting signals to other devices such as brakes, throttles and cruise controls. When control housing is not in use, magnetized members (38a) and (38b) cause a rotation to hide surface grip (32) under covering grip (33).
