ABSTRACT:
An improved solenoid and reset pin for a modular display apparatus for displaying indicia at a front thereof having a frame for rotationally mounting a plurality of pixels. Each pixel includes first and second display faces joined along respective adjacent edges. A triggering mechanism has a plurality of solenoids adapted for selective actuation to rotate selected ones of the pixels for changing the pattern of the desired display indicia and a plurality reset pins to return the pixels to an original position. The reset pins and the plungers for the solenoids include a spring and a rod extending axially outward from said spring to provide radial flexibility.
