A support plate for mounting one or more potentiometers includes a receptor for receiving a potentiometer and alignment tabs for guiding the potentiometer into position and preventing it from rotating during mounting. The potentiometer may be secured to the alignment plate through the application of clamping force produced by torquing a lock nut on the threaded stem of the potentiometer. The alignment tabs prevent the potentiometer from rotating during the application of the clamping force so that the contacts of the potentiometer maintain a predetermined position.

A mounting for the electronic components of computer system's functional control unit comprises a housing for supporting a display unit and for enclosing an electronics chassis comprising electronics to control access to a variety of peripheral units. The electronics chassis is removably mounted within the housing on slide rails so as to be removed, serviced or replaced without having to lift the terminal off the housing of the functional control unit. The mounting thus simplifies the installation and maintenance procedures for computer systems.
