ABSTRACT:
A pressure-actuated switch mounted in the handle of a self-inking stamper is actuated by a stationary plunger assembly which extends into the handle and pressures the switch when the stamp element is moved into contact with a surface being marked. Actuation of the switch advances a counting circuit remotely located inside the lid of a lockable box. A circuit times the stamp element in the stamping position to avoid multiple markings on a single count.
