Ultra Subminiature Basic Switch
Snap-action Switch with Ultra
Subminiature Size (6.5 8.2
(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.

D2MQ D2MQ Precautions Refer to pages 26 to 31 for common precautions. Correct Use Cautions Mounting Terminal Connections Use M1.4 mounting screws with screws to securely mount the Switch. Tighten the screws to a torque of 0.1 N S m {1 kgf S cm}. Make sure that the capacity of the soldering iron is 15 W maximum (temperature of soldering iron: 250°C max.). - Page 6 General Information General Information Correct Use Electrical Conditions Area Item Page Load Using Switches The switching capacity of a switch significantly differs depending on Selecting Correct Switch whether the switch is used to break an alternating current or a direct Electrical Load current.
