8LM2TB106

1. Overview

The Lovato Electric 8LM2TB106 is a 22 mm blue flush pushbutton actuator from Lovato's 8LM "Platinum" metal control-device series — spring-return (momentary), non-illuminated. Per Lovato's catalog it is a pushbutton actuator (operator head): in the 8LM modular system the actuator takes a separate contact element (8LM2TC.. for NO/NC) on a holder. Blue conventionally denotes a mandatory action / information / defined special function. (Data-quality note: this was cataloged with a "1 NO" contact — the 8LM actuator has no integral contact; the contact element is ordered separately. Same modular pattern as #477/#478/#492 (8LM), ABB MP, and Eaton M22 heads.)

2. User Sentiment

Lovato's 8LM Platinum line is a well-built, value European 22 mm system — metal bezels, broad modular selection, good availability. The flexibility (actuator + chosen contacts) is the plus; the common pitfall is that the actuator alone isn't a working button — add the contact element and holder.

3. Real-World Applications

A blue (mandatory-action / information / auxiliary) flush momentary button on machine and control panels — the installer adds the required NO/NC contact element(s).

4. Technical Specifications

• Type: Lovato 8LM Platinum pushbutton actuator (head), 22 mm, metal, flush
• Actuator: flush, spring-return (momentary); blue; non-illuminated
• Contacts: none integral — add Lovato 8LM2TC contact element(s) + holder
• Cutout: 22 mm
• Sealing: IP65 (assembled)
• Approvals: CE, UL

5. Ordering & Compatibility

Order the 8LM2TB106 actuator plus the required contact element(s) and holder. Fits standard 22 mm cutouts, 8LM Platinum system. Color codes: 03 = green, 04 = red, 05 = yellow, 06 = blue (this); plastic 8LM2M is the economy line.

6. Known Issues / DQ

• DQ: it's a modular actuator (head) with no integral contact — the stored "1 NO" was misattributed. Corrected here (contact → separate 8LM2TC element).
• Practical care: order the contact element + holder separately, confirm the 22 mm cutout, and match the contact configuration to the circuit.
