Abstract
The capacitance to ground of a metallic ornament is included in an oscillator. When a person touches the ornament, the period of the oscillator increases. The increased period causes a change of state of a bistable latch. In response to the change of state, a silicon controlled rectifier either provides a path for current through a lamp or prevents a flow of current therethrough. The metallic ornament is preferably a Christmas tree ornament or light.
