ZB4-BW113

1. Overview

The ZB4BW113 is the metal operator head for a Harmony XB4/ZB4 22mm illuminated pushbutton — one piece of a modular "build your own switch" system where head, contact block(s), and lamp module are separate part numbers snapped together. Schneider's own datasheet titles it "white projecting illuminated pushbutton head Ø22, spring return, for integral LED," and DigiKey categorizes it under "Configurable Switch Bodies," noting it "Requires Contact Block(s), Illumination Source." Distributors (Radwell, MISUMI, Newark, Zoro, Crescent Electric) all echo this: it's a head/actuator, not a complete switch.

2. User Sentiment

No forum, review, or community discussion specific to this part number turned up across 835 pre-filtered sources — this is an industrial-automation component, not a consumer product. The closest thing to sentiment is distributor marketing copy (Crescent Electric, se.com) calling it "clearly distinguishable visually at a distance thanks to clear color and by touch due to projecting element, minimizing errors in machine control."

3. Real-World Applications

Used on industrial control panels, machinery HMI/operator stations, and process equipment wherever a 22mm illuminated momentary pushbutton is needed. Notably, its certification list (BV, DNV, GL, LROS, RINA — all marine classification societies — plus UL/CSA) signals frequent use in shipboard and offshore control panels alongside general factory-floor equipment.

4. Technical Specifications

• Type: Head only, for illuminated pushbutton (Harmony XB4 metal range) — not a complete switch
• Color: White (confirmed: "White projecting unmarked" per Schneider datasheet; "白色" per RS China; "blanc"/"weiß"/"bianco" per FR/DE/IT Schneider sites)
• Profile: Projecting/extended (raised button), NOT flush — "vorstehend" (DE), "dépassant" (FR), "Extended" (Zoro/Crescent/Radwell) all agree
• LED: Head is "for integral LED" / "for universal LED" (compatible with a snap-in LED light block) but does not include the lamp — RS China explicitly notes "plain lens without integrated lighting"; Walmart's listing title reads "No Lamp"; Radwell cross-refs it as "PUSHBUTTON SWITCH ONLY... NONILLUMINATED." No LED voltage value appears anywhere in Schneider's own datasheet.
• Contact block: None integral — separate ZBE-10x (or double) contact blocks snap on behind the head; datasheet's "electrical composition codes" (M1/M2/M6/M10) describe optional combinations, all achieved with add-on blocks
• IP rating: IP66 (IEC 60529) and IP69 and IP69K; also NEMA 13/4X, IK05
• Material: Chromium-plated metal bezel (China listing: nickel-plated)
• Dimensions: 22mm mounting diameter, 28.5mm button face, ~29×29×33mm overall, 29g
• Certifications: UL listed, CSA, BV, DNV, GL, LROS, RINA (EN/IEC 60947 series, UL 508, JIS C 4520)

5. Ordering & Compatibility

Priced around $9-10 (DigiKey unit price $9.79) for the head alone. Requires a separate contact block (e.g., ZBE-101 = 1 N/O, ZBE-102 = 1 N/C) and a separate LED light-block/lamp module (its voltage is a property of that module, not the head) to become a functional switch. Radwell sells bundled "ZB4BW113-SUB-1 N/O-KIT" and "N/C-KIT" substitutes pairing the head with a specific contact block. Sibling ZB4BW113S / ZB4BW113S7 share the identical description, suggesting packaging/retention variants rather than functional differences. The fully pre-assembled, ready-to-use unit in this family is designated XB4-BW..., distinct from the ZB4-BW... head component.
