Siemens A6X30138430 — Illuminated Pushbutton Body, Clear
Overview
In a 22mm modular operator station, the pushbutton body forms the primary human-machine interface element. The Siemens A6X30138430 is an illuminated pushbutton body from the 3SU1 series designed for clear-lens applications in industrial control circuits. It requires separate contact block(s) and an illumination source to function as a complete operator. The component ships as a standalone actuator head; lamp and contact elements are ordered independently.

Functional Requirements and Design Context
Assembly Requirements
The A6X30138430 is a modular pushbutton body. To complete a functional operator, two additional elements must be selected from the 3SU1 catalog:
- Contact block(s): Required to establish electrical switching function in the control circuit.
- Illumination source: Required to provide backlighting for the clear lens.
This follows the standard 3SU1 series ordering model where actuator heads, contact modules, and lamp elements are cataloged as separate line items.
Physical Integration
The body accepts a 22.3mm round panel cutout, consistent with the stated 22mm switch family compatibility. The encapsulation is listed as Box, indicating the packaged form factor of the actuator head.
Catalog Comparison — 3SU1 Illuminated and Non-Illuminated Pushbutton Bodies
| MPN | Title | Illumination | Requires | Similarity |
|---|---|---|---|---|
| A6X30138430 (seed) | ILLUMINATED PUSHBUTTON. CLEAR | Illuminated | Contact Block(s), Illumination Source | 1.00 |
| A6X30138448 | ILLUMINATED PUSHBUTTON. YELLOW | Illuminated | Contact Block(s), Illumination Source | 0.96 |
| A6X30138411 | ILLUMINATED PUSHBUTTON. YELLOW | Illuminated | Contact Block(s), Illumination Source | 0.96 |
| A6X30138304 | PUSHBUTTON. BLUE | Non-Illuminated | Contact Block(s) | 0.92 |
All comparison rows share: identical series (3SU1), actuator type (Pushbutton, Round), panel cutout dimensions (22.3mm Round), encapsulation (Box), and ROHS3 Compliant status.
Why A6X30138448 and A6X30138411 are similar: Both share the same series, illuminated configuration, contact block and illumination source requirements, and mechanical envelope. The only recorded difference is lens color (yellow vs clear), which affects operator indication color without changing the body form factor or mounting requirements.
Why A6X30138304 differs: This variant records non-illuminated actuation and does not require an illumination source, reducing assembly complexity when a backlit operator is not needed. The mechanical and compliance specifications remain identical.
FAQ
What distinguishes the A6X30138430 from the yellow-illuminated variants A6X30138448 and A6X30138411? The clear lens designation indicates a transparent or colorless lens suitable for applications where the operator prefers uncolored illumination or where custom indication colors are achieved through a replaceable lamp source.
Is the illumination source included with the A6X30138430 body? No. The record lists illumination source as a separate required item. The pushbutton body must be paired with a compatible lamp element from the 3SU1 series to provide backlighting.
What contact configuration does the A6X30138430 support? The body accepts contact block(s) from the 3SU1 modular system. Specific contact arrangement (NO/NC count, late-break, early-make) depends on the selected contact block — that parameter is not recorded in this catalog entry.
