MITSUMI Rotary Encoder Switches SRE Series Switches FEATURES 1. Mounting area is small ( 18mm). 2. SMT Correspondence Type (Reflow Solder Correspondence). 3. 12/24 detent is prepared as standard. 4. Mounting of thin shape tactile switch : SOT series and 4 direction operation switch : SOQ series is possible into an extraction portion. 5. By the composite with a 4 direction operation + center push, compound operation of seven directions is possible. 6. The example of 4 direction operation + center push mounting use. Character control of LCD is performed by the encoder. And, an inside can be used as five function switches. 7. The mounting height to the operation knob is 4.5mm (SOQ), 2.95mm (SOT), and thin shapeized realization. < Compound form example > SRE only A combination with 4/5 direction control switch. Mounting height 4.5mm SRE + SOQ Mounting example A combination with light pattern Tactile switches. Mounting height 2.95mm SRE + SOT Mounting example USES 1. Cellular phone · PDA · digital camera · car audio · other portable apparatus.
