The municipality's arms might be described thus: Per bend sinister Or a lion rampant sinister gules armed and langued azure and vert in base an attire of four points fesswise above which a birch leaf palewise, both of the ﬁrst.
The charge on the dexter (armsbearer's right, viewer's left) side, the lion, is drawn from the arms once borne by the Waldgraves, among whose holdings was Hausweiler.
