Catalog peers listed require individual qualification; similarity scores do not constitute interchange approval.

Why A6X30136444 is similar: Both parts share the Siemens 3SU1 series, 22.3mm round panel cutout, non-illuminated construction, and box packaging. The actuator type differs (keylock vs round pushbutton), which affects the human-machine interface function but not the mounting or contact-block interface.

Why A6X30136414 is similar: Identical series, cutout, illumination, and packaging specifications. This row substitutes a multi-position selector (O-I-II-III) for the keylock, serving different operator-control scenarios while preserving the same backend contact-block attachment.

Why A6X30136463 is similar: Both belong to the same 3SU1 family and require the same contact blocks. The coordinate switch provides four switch positions versus the two-position keylock, broadening control flexibility while using the identical panel footprint.

Ordering Note — Siemens 3SU1 Family Context

The 3SU1 series covers a broad range of 22mm human-machine interface devices. MPN prefix A6X30 identifies the body/operator component; matching contact blocks (ordered separately) complete the switching function. This keylock variant supports two positions (O-I) and requires at least one contact block for circuit completion.

FAQ

Does the A6X30136424 include contact blocks? No — the body requires separate contact blocks for electrical function. The catalog record specifies "Contact Block(s)" as a required accessory.

What panel cutout does this switch require? The specified cutout is 22.3mm round, consistent with the Siemens 22mm device series.

What is the difference between the keylock and selector variants in this series? The A6X30136424 provides keylock actuation with two maintained positions (O-I). The selector variant A6X30136414 offers four positions (O-I-II-III) operated by a rotary lever without key retention.
