Omron A3d Series Illuminated Latching Push Button Switch Panel Mount 8 mm Cutout SPST LED A3DJ-7121

The Omron A3d Series A3DJ-7121 Illuminated Push Button Switch is engineered for industrial automation and control applications. This panel-mounted switch features a compact 8 mm cutout size and offers latching switch operation, which maintains the ON/OFF state without the need for continuous pressing. Available with green, red, white, and yellow LED illumination, it provides excellent visibility in dimly lit environments.

This push button switch utilizes a Single Pole Single Throw (SPST) contact configuration with solder terminals to ensure robust electrical connections. It is rated to handle a contact current of 100mA at 30V DC and 24V AC, making it well-suited for low-power switching tasks commonly found in control panels and automation systems.

Specifically designed for panel mounting, the device features an actuator style button with a rectangular form factor for ergonomic use. Its operating temperature range from -10°C to +55°C ensures dependable performance in a variety of industrial settings. The IP40 ingress protection rating provides resistance against solid foreign objects larger than 1 mm, though it is not suitable for exposure to water.

The switch complies with relevant international standards including CSS, CE, and UL, assuring safety and quality in demanding applications. It is widely used in industrial machinery control panels, automation systems, electrical enclosures, commercial lighting systems, as well as safety and alarm systems for effective user interaction.
