SUBMINIATURE Basic Switch D2MQ Subminiature Basic Switch ■ ■ ■ ■ ■ Super compact switch weighing only 0.3 g. Ideal for reducing equipment weight Angle terminal allows operation from the side when mounted to a PCB Despite its compact size, the snap action mechanism gives it superior electrical characteristics Silver-plated contact. Gold-plated contact also available for loads under 50 mA Ideal for use on equipment with stringent space and reliability requirements, such as in compact audio equipment, optical devices, and communications equipment Ordering Information Pin plunger Leaf lever Straight terminal Left-angle terminal Right-angle terminal Actuator Pin plunger Contact Silver-plated (Ag-P) Part Number Straight Terminal D2MQ-1 Left-angle Terminal D2MQ-1-TL Right-angle Terminal D2MQ-1-TR Leaf lever Gold-plated (Au-P) Silver-plated (Ag-P) Gold-plated (Au-P) D2MQ-1-105 D2MQ-1L D2MQ-1L-105 — D2MQ-1L-TL — — D2MQ-1L-TR — Note: The angle of the terminal illustration above is from the side of the arrow shown on the right. ■ CONTACT FORM Specifications Ratings Electrical ratings Inrush current Ag-Plated contact: 50 to 500 mA, 30 VDC (resistive load) Au-Plated contact: 5 to 50 mA, 30 VDC (resistive load) NC: 0.5 A max.

Holding the switch at the free position, solder the lead wire to its terminal within 3 seconds, using a soldering iron rated at less than 15 W with a tip temperature of less than 280°C. Excess wattage or prolonged heating can deteriorate the electrical characteristics of the switch. Mounting hole matching dimensions ■ OPERATION When mounting onto a metal body, always install a separator between the switch and the mounting panel. Set the operating force of the pushbutton and leaf lever at less than twice the OF standard value. Design the insulation separator (made up of hard material) into the shape shown below. Always make the OT value larger than the specification value. Separator shape Do not operate at extremely slow speed; also do not use the switch with its pushbutton located between the free position and the operating position. Do not change the operating position of the actuator. Mount the pin pushbutton type in such a way that the stroke of the pushbutton and the stroke of the operating control overlap on a vertical line. Do not operate the switch roughly as it may deteriorate the functions of the switch. Do not apply excessive force to the actuator of the leaf lever type along its operating direction, opposite to its operating direction, or in the lateral direction. Omron Europe B.V.
