A message-note holder has a fixed jaw member and a pivotal jaw member which is biassed toward the fixed jaw member by its own inherent springiness, which is achieved by the material from which it is made and by placing it in tension. The space between the lower ends of the jaw members defines the volume where a message-note is held by the note-holder of the invention. The pivotal jaw member has a laterally-projecting tubular member which is telescopingly and rotatably received within a tubular housing formed in the fixed jaw member, by which the two jaw members are rotatably coupled together. Within the tubular member of the pivotal jaw member there is provided an on-off switch for turning on and turning off a LED in alternating sequence of rotations or "squeezings" of the pivotal jaw member with respect to the fixed jaw member. Thus, when the pivotal jaw member is rotated for inserting a message-note between the lower ends of the jaw members, the switch closes a battery-powered circuit to energize the LED. When the note is removed by the person for whom the message was intended, or the like, by again rotating the pivotal jaw member, the switch de-energizes the LED. The switch has a first ratchet wheel rotatable with the rotatable tubular member of the pivotal jaw member. This first ratchet wheel meshes with a second ratchet wheel, which meshes with mating teeth on an interior-facing surface face of a stationary LED-housing assembly. The ratchet wheels are biased together via a spring that its ends contacts the LED power electrode and at its other end of the battery source. The switch moves one end into or out of contact with the LED for making or breaking the electrical circuit.
