Title:
ELECTRONIC DIAL
Document Type and Number:
Japanese Patent JPH1131435
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide such an inexpensive electronic dial that generates a signal corresponding to the rotational angle of the dial with a saved space. SOLUTION: An electric conductor ball 16 which is stored in a space formed by a cam groove 18 crossing a switch groove 12 to always contact a ground terminal 20 is moved in the switch groove 12 with the rotation of the rotating member 14 of a dial to selectively contact one of contact terminals 21a-21f corresponding to the rotational angle of the rotating member 14. In this way, the ground terminal 20 is short-circuited with one contact terminal to generate a signal corresponding to the short-circuited contact terminal.
