A DUAL FEELING ROTARY SWITCH

摘要

PURPOSE: A dual feeling rotary switch is provided to prevent operation noise by generating the click feeling by the magnetic force of a magnetic ring and an electromagnet with a noncontact method. CONSTITUTION: A button(10) pressurizes a switch terminal of a circuit board. A signal sensing unit(60) operates a sensor installed in the circuit board. A detent unit(70) generates the click feeling when a rotary structure(50) is rotated. The detent unit includes a pair of magnet rings and a pair of electromagnets. The pair of magnet rings are fixed in a lower side of the signal sensing unit. The pair of magnet rings form the different click feeling. The pair of electromagnets are arranged on the circuit board to face the pair of magnet rings.
