Match by reference first
Search the marking on the switch.
Part-number searches are usually the quickest way to find a replacement. CtrlOn stocks references including LXW5-11Q1, LXW5-11Q2, ME-8108, ME-8104, ME-9101, XZ-1108, XZ-9104 and XZ-15GW-B. A visually similar switch can still have a different actuator, contact arrangement, travel or electrical rating, so the reference and application should be checked before fitting.
If the reference is unreadable, send a clear photo of the complete switch, the label or moulded markings, terminal arrangement and the equipment nameplate. CtrlOn can help identify the component or source an alternative where appropriate.
