Abstract: 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.

Abstract: A wire insertion tool for inserting individual wires into an insulation displacement contact of an electrical connector includes a wire insertion head; a palm handle; a wire insertion punch disposed on a forward end of the palm handle; means for mounting the palm handle to the wire insertion head such that the punch can be reciprocated towards and away from the wire insertion head by grasping the palm handle and the finger grip of the wire insertion head; a connector positioning means for positioning a connector opposite the wire insertion punch; and bench mounting means formed along a distal edge of the wire insertion head for engaging a structural feature on a removable bench mounting block secured to a mounting surface to releasably secure the wire insertion tool to the mounting surface for use as a bench mounted tool. A palm button can be removably mounted to the palm handle when the tool is bench mounted to provide a greater handle surface area.
