Aci 116017 Limit Switch Safety Key Fd Fp Fl Fs Series

Product Description

The ACI 116017 is a replacement safety key accessory designed for use with limit switch assemblies in industrial and commercial control applications. The key measures 31.5 millimeters in overall length and serves as a mechanical actuation or interlock component within compatible safety switch housings. Weighing 0.3 pounds, this compact part is typically installed by licensed electricians or qualified control system technicians during routine maintenance, switch replacement, or system commissioning. It is sold individually and requires no special tools beyond those standard to electrical panel and safety switch work.

This safety key is specified for use with FD, FP, FL, and FS Series safety switches. These switch families are commonly found in industrial machinery, HVAC equipment controls, and electrical distribution enclosures where limit or safety switching functions are required. The 116017 is the appropriate replacement or spare key when the original has been lost, damaged, or worn, and is an exact-fit accessory for the listed switch series rather than a universal or aftermarket substitute.
