I am looking for a miniature DC 18 volt timer with an on/off push button that will also turn to adjust a timer from 5 to 30 minutes. The push button needs to be wired to a bread board with a 4 inch wire lead.

More information is needed.

The ICM7555 can probably do this but a potentiometer will be needed to adjust the delay.

A microcontroller can be used to build a more flexible timing device but will need a voltage regulator (5V or 3.3V) and an output buffer to interface with the 18V devices.
