Ultra-small Tactile Switch
Ultra-small-sized Tactile Switch with
High Contact Reliability:
1.2 × 3 × 2.5 mm (H × W × D)
Industry’s smallest switch* allows high-density
mounting on PCBs for mobile equipment.
*As of October 2006 (according to OMRON survey).
Dust-proof construction provides high reliability in
dusty environments.
Surface mounted: Ideal for high-density mounting.
Models with ground terminals are available for
protection against static electricity.
RoHS Compliant

    ... Make sure that the polarity of the LEDs is correct. The polarity is not indicated on the Switch, but the positive pole is located on the back surface of the Switch on the side without the OMRON mark. Connect limiting resistors to the LEDs. The Switch does not have built-in limiting resistors, so satisfy the LED characteristics by obtaining the limiting resistance according to the following formula based on the voltage to be used ...
