Patent

CA 2179957

An illuminated sign, such as an emergency exit sign, includes a stencil in which a pair of oppositely- directed, arrow-shaped through-holes are disposed. At least one arrow-shaped snap-in element is provided which is inserted into either of the through-holes to block the passage of light therethrough. The snap-in element includes elastic spring fingers having hook- shaped ends adapted to engage a rear end of a ridge which borders a rear side of a respective through-hole, thereby yieldably retaining the snap-in element within the through-hole. All of the spring-fingers are movable simultaneously through a respective through-hole.
