Product Identity
The Siemens 52BP2D2A is a 30 mm illuminated push button with a red 44 mm mushroom head. It provides 1NO/1NC contacts rated at 10A @ 600V AC and operates on 24V AC/DC incandescent lamp voltage. The unit carries NEMA ratings 1, 3, 3R, 4, 4X, 12, 13 for industrial control panels.
Installation Checks
Verify the panel cutout suits a 30 mm operator with a 44 mm mushroom head and black epoxy coated zinc die cast bezel. Confirm the control circuit supplies 24V AC/DC for the full voltage incandescent lamp module. Ensure the A600/P600 contact rating matches the intended load and wiring scheme.
Thermal Noise Power
The incandescent lamp generates modest heat during continuous illumination at 24V. Mechanical operation is silent aside from the maintained push pull action. Power draw is limited to the lamp circuit and the 10A rated contacts switching the external load.

Questions about this item
What comes in the box and what must I source separately?
The unit includes the illuminated push button with a 44 mm mushroom head, black epoxy coated zinc die cast bezel, and an incandescent lamp module rated for 24 V AC/DC; a replacement lamp (part 52AADN) is not included and must be purchased separately.
Which version should I choose for a maintained push-pull action at 24 V?
This model provides maintained pull and maintained push operation with a red 30 mm operator, 1NO/1NC contacts rated 10 A at 600 V AC, and a 24 V AC/DC full voltage incandescent lamp — select it when those exact specifications match your control circuit.
What does the 10 A contact rating mean in actual use?
The contacts are rated to switch up to 10 A at 600 V AC (NEMA A600/P600), so the button can directly control motor starters, contactors or similar loads within that current and voltage limit without an intermediate relay.
