Ultra Subminiature Basic Switch

D2MQ

Snap-action Switch with Ultra

Subminiature Size (6.5 8.2 2.7 mm

(H W D)) and Light Weight (0.3 g)

Excellent electrical characteristics and a snap-ac-

tion mechanism in spite of its ultra small size.

Gold-plated (Au-P) contacts for micro load

switching available in addition to silver-plated

contacts (Ag-P).

Ideal for applications where size is extremely

limited and high reliability is demanded, such as in

compact audio, optical. and telecommunications

equipment.

Unless otherwise specified, a tolerance of 0.15 mm applies to all dimensions. 3. The following illustrations are for the straight terminal models. Those for the left-angled terminals and right-angled terminals are different from straight terminal models in terminal size only. Refer to Terminals on page 211 for these terminals. 4.

D2MQ D2MQ Precautions Refer to pages 26 to 31 for common precautions. Cautions Correct Use Mounting Terminal Connections Make sure that the capacity of the soldering iron is 15 W maximum (temperature of soldering iron: 250°C max.). Do not take more than 3 s to solder the switch terminal.

General Information General Information Correct Use No. Area No.
PAGE 7
General Information General Information Contact Protective Circuit When a switch is used under high humidity, arcs resulting from certain types of load (e.g., inductive loads) will generate nitrious oxides and, with mater the nitrious oxides will become nitric acid, which will corrode internal metal parts and may cause malfunctions. Always use a contact protective circuit according to information provided in the following table when using a switch under circuit conditions of frequent switching and arcing.

General Information General Information Switching Speed and Frequency Mechanical Conditions Operating Stroke Setting Contact force Operating force The setting of stroke is very important for a switch to operate with high reliability. The chart below shows the relationship among operating force, stroke, and contact force. To obtain high reliability from a switch, a switch actuator must be manipulated within an appropriate range of operating force.
PAGE 9
General Information General Information Incorrect • Do not modify the actuator. If the actuator is modified, excessive external force may be applied to the internal switch mechanism, characteristics may change, and the switch may stop functioning. • If an external actuator is used as an operating object, check the material and thickness of the lever to make sure that the force applied to the lever is within the permissible range.

General Information General Information terminals, otherwise the terminal may be deformed or the housing may be damaged. Wiring Work When wiring a switch, check the insulation distance between the switch and the mounting plate. If the insulation distance is insufficient, use an insulation guard or separator. Be particularly careful when mounting a switch to metal. Use wire sizes suitable for the applied voltage and carrying current. Do not wire a switch while power is being supplied.

General Information General Information Switch Trouble and Corrective Action Type Failures related l t d tto electrical characteristics Location of failure Contact Failure Contact f il failure Possible cause Dust and dirt on the contacts. Water or other liquid has penetrated into a switch. Chemical substances have been generated on the contact surface due to the atmosphere containing chemical corrosive gas.
