A22-TY-10M

1. Overview

The Omron A22-TY-10M is a 22mm round-body non-illuminated pushbutton switch from Omron's A22 series — a long-running, internationally distributed industrial control switch family. It features a projecting (extended) round actuator in yellow, with a single normally-open contact and momentary (self-resetting) action. The A22 series accommodates both 22mm and 25mm panel cutouts (the latter requires an adapter ring). The product is now obsolete/discontinued per Omron and major distributors (DigiKey, ABC Semi, Ciiva), though aftermarket stock remains available from secondary distributors. The part was manufactured in Taiwan/Japan and carries a datasheet dated 1998, confirming it is a legacy product.

2. User Sentiment

No forum discussions, user reviews, or community comparisons were found specifically for the A22-TY-10M in the research findings. The Amazon Canada listing provides the most complete public-facing product description (confirmed: projection type, non-lighted, momentary, IP65) but no customer reviews were captured. The product's widespread secondary market availability (multiple distributors globally carrying 3,000–7,400+ units in stock) suggests sustained industrial demand even post-discontinuation. Related A22 variants appear in industrial automation contexts without specific complaints noted.

3. Real-World Applications

The A22 series is a standard 22mm industrial control pushbutton widely used in machine control panels, automation equipment, and industrial control cabinets. The projecting actuator style is common in applications where tactile feel and easy actuation without precise alignment is important (e.g., operator control stations, conveyor systems, and general-purpose panel controls). The IP65 oil-resistant rating makes it suitable for light-duty manufacturing environments where splash and dust protection is needed. A companion part A22-TY-01M provides the 1NC contact variant for interlocking and stop-circuit applications.

4. Technical Specifications

• Type: Standard (non-illuminated), projecting round pushbutton — confirmed non-illuminated (非照光式, 不带灯型) per Omron Japan/Chinese documentation; the A22L prefix designates the illuminated variant
• Series: Omron A22 (round body φ22/φ25)
• Part Number Decode: A22 = 22mm round body; T = projecting/extended actuator (突出形); Y = Yellow; 10 = 1NO contact (SPST-NO); M = Momentary (self-resetting); companion A22-TY-10A uses A = Alternate/maintained action
• Color: Yellow (YLW)
• Action: Momentary (Off-Mom / self-resetting)
• Circuit: SPST-NO (Single Pole Single Throw, Normally Open) — 1NO, 0NC
• Current Rating: 10A (AC/DC)
• Voltage Rating: 110V AC / 24V DC
• Panel Cutout: 22.30mm circular; also fits 25mm cutout with adapter ring
• Termination: Screw terminal
• Mounting: Panel Mount, Front
• IP Rating: IP65 — Dust Tight, Oil and Water Resistant (confirmed for non-illuminated models)
• Mechanical Life: 5,000,000 cycles
• Electrical Life: 500,000 cycles
• Operating Temperature: -20°C to +70°C
• Standards/Certifications: UL, CE; IEC EN60947-5-1 confirmed; RoHS compliant (lead-free)
• Packaging: Bulk; MSL 1 (Unlimited)
• Complete vs. Component: The A22-TY-10M is a complete assembled unit (actuator head + switch unit integrated); the A22 series allows separate ordering of switch units (e.g., A22-10 contact block) but the A22-TY-10M ships as a ready-to-install complete switch with contacts included

5. Ordering & Compatibility

The A22-TY-10M was previously stocked at DigiKey under PN Z3596-ND / A22-TY-10M-ND but is now discontinued there. Historical pricing was approximately $10.16–$15.34 per unit. Mouser (multiple regions: US, India, Singapore, Ireland, South Africa, Taiwan, etc.) and secondary distributors carry remaining stock. The A22 series includes a wide family of compatible variants: A22-TY-01M (1NC, same yellow projecting), A22-TR-01M (red projecting 1NC), A22-TY-20M (yellow projecting 2NO DPST-NO), and illuminated equivalents with the A22L prefix (e.g., A22L-TY-T1-10M, A22L-TY-T2-20M). The switch unit sub-assembly can be replaced independently. The product is compatible with 22mm or 25mm panel cutouts (25mm requires an adapter ring).

6. Known Issues

The product is obsolete/discontinued per Omron and DigiKey, which is the primary procurement concern. Some distributor listings and third-party catalog sites (including JAK Electronics and Utmel) incorrectly categorize the A22-TY-10M as "Illuminated Pushbutton Switches" — this is a miscategorization; all authoritative sources (Omron Japan Aperza portal, Chinese product page, Amazon CA, FTC Electronics) confirm it is non-illuminated (no lamp/LED). The Button Index catalog entry also has a data-quality issue: it labels the product "22mm Yellow Illuminated Flush 24V" and subcategory "illuminated-flush" — both are incorrect; the correct description is non-illuminated and projecting (not flush). No mechanical or reliability issues were reported.
