This keylock switch is part of the Siemens 3SU1 operator station platform. It is a front-panel actuator body designed for a 22.3mm round panel cutout in industrial control enclosures. The unit is non-illuminated and requires separate contact blocks (ordered independently) to complete the switching function. The body ships as a box-encapsulated component and carries ROHS3 compliance status.
Series Context — 3SU1 Platform
The 3SU1 series covers the Siemens 22mm modular operator station line. Actuator bodies like the A6X30136923 accept snap-fit contact blocks on the rear — typically single-pole or double-pole modules depending on the circuit configuration. Key-operated variants in this family provide mechanical latching positions that differ by internal cam profile; the title notation "O.M.R. O<I" refers to the specific position sequence encoded on the internal mechanism.
Physical Integration Notes
The 22.3mm round cutout is the standard Siemens 22mm panel dimension for this series. Keylock actuators project forward from the panel face and require adequate clearance behind the mounting plane for the contact block assembly. The box encapsulation describes the shipping/package form factor, not the enclosure IP rating.

Why A6X30136925 is Similar
Shares the same actuator type (Keylock), series (3SU1), and panel cutout specification. The MPN shares the first 10 characters with identical prefix structure, indicating the same functional variant within the family.
Why A6X30136920 is Similar
Matches the A6X30136923 on all shared spec keys — keylock type, 3SU1 series, 22.3mm round cutout, and requires contact blocks. The difference lies in the cam profile encoding ("I-O" vs "O<I" position sequence).
Why A6X30136903 is Similar
Shares the same parameter set as the primary part across actuator type, series, encapsulation, and cutout dimensions. The MPN prefix differs by one character, placing it in the same ordering-code family with a similarity of 0.96.
The remaining alternates (A6X30136928, A6X30136929, A6X30136926, A6X30136936) are pushbutton variants within the same series. They share the 22.3mm cutout, contact block requirement, and ROHS3 status but differ in actuator type — round pushbutton rather than keylock.
FAQ
Q: Does the A6X30136923 include contact blocks? No. The catalog listing specifies that this actuator body requires contact block(s) ordered separately. The switching elements are not built into the actuator body.
Q: What panel cutout is required for this switch? A 22.3mm round hole is specified, consistent with the Siemens 22mm operator station standard.
Q: Is the A6X30136903 interchangeable with the A6X30136923? Both parts share identical specifications for actuator type, series, cutout, illumination, and contact block requirement. They belong to the same 3SU1 ordering-code family, though final interchangeability remains subject to the user's qualification process.
