Siemens 52RB3D2 Mushroom Pushbutton Accessory

Product Description

The SIEMENS 52RB3D2 is a mushroom-head pushbutton accessory designed for use with compatible industrial control pushbutton assemblies. The mushroom-style actuator provides a large, easy-to-target contact surface, making it well suited for applications that require quick operator response or emergency-stop-style actuation. At 0.044 pounds and compact in form, the 52RB3D2 is a direct-mount accessory that attaches to a base pushbutton body to complete the operator interface. Electricians and industrial controls technicians are the primary installers of this type of component.

This mushroom actuator accessory is typically used in industrial control panel applications, machine tool stations, and process equipment operator interfaces. It pairs with compatible Siemens pushbutton base units and is appropriate for both light industrial and heavy-duty control station installations where a larger actuator head improves usability or meets operator safety requirements.

Key Features

• Mushroom-head actuator profile for increased contact surface area
• Compact and lightweight at 0.044 pounds

Installation Notes
