ABSTRACT:
An electrical meter apparatus wherein the elements of construction of the meter are so constructed as to not warrant any significant amount of precision in manufacture. A selector knob is connected to a switch rotor with a switch rotor being mounted upon a panel bushing which is fixedly connected to the meter housing. A limited amount of canting movement is permitted along with the normal rotative movement between the switch rotor and the panel bushing. The switch rotor is connected in a non-precision manner with a socket and a plug. The plug is loose fittingly connected within an opening in the printed circuit board of the meter. A limited amount of canting movement of the plug is capable of occurring with respect to the printed circuit board. A single electrical contact member is fixed to the panel bushing and includes on opposite sides thereof resilient electrical contact elements which are to physically contact the printed circuit board and tend to maintain the plug in axially alignment within the opening.
