Eaton 10250TM42 industrial power supply legend plate half round off on black 30.5 mm

Industrial selector-switch legend plate

The Eaton 10250TM42 is a half-round aluminium legend plate sized for 30.5 mm selector switches and roto-push operators. It carries the permanent Off-On marking in black on a black background for clear status identification in industrial panels. The 1.75 in height and width match standard cut-out dimensions.

Fixed legend limits flexibility

Because the Off-On text is stamped into the plate it cannot be changed to custom wording or additional positions. The half-round shape only fits operators that accept a 30 mm diameter legend, so it will not mount on square or rectangular bezels. Installers must verify the operator cut-out before ordering.

30.5 mm mounting diameter decides fit

The single specification that determines compatibility is the 30.5 mm operator size. If the switch or push-button uses that exact mounting diameter the plate will seat correctly; any other diameter means the part cannot be used.
