Abstract
A dial system for steering wheel of an automobile is divided into two portions electrically connected by a cable and each includes a first casing and a dial set received in the first housing. The dial set includes a number button partially extending the first housing for being operated. A circuit board is received in the first housing for wirelessly transmitting signals when the buttons are operated. A second housing is mounted to the first housing to form a space for receiving the dial set and the circuit board. A battery seat with battery is laterally inserted into the space for providing power to the circuit board. A clamp is mounted to a bottom of the second housing and clamps the steering wheel to hold the dial system in place on the steering wheel for an easy operation.
