D2MQ-1 – OMRON

Overview

The Omron D2MQ-1 is a subminiature SPDT (Single Pole Double Throw) snap-action switch designed for precise actuation in compact electronic assemblies. Its critical operational characteristic lies in its reliable, repeatable contact switching at a low operating force of 1.2 N, ensuring consistent signal routing. A key design consideration often overlooked is the trade-off between its subminiature form factor and its 500 mA current rating; while space-saving, designers must carefully manage power dissipation to prevent premature contact degradation in higher-current applications.

Key Features

• Contact Form: SPDT
• Current Rating: 500 mA @ 30 VDC
• Operating Force: 1.2 N (Max)
• Termination Style: Solder Lug
