Review: Great products - I stopped buying the cheaper Chinese brand Murphy switches recently. They don't last nearly as long compared to the actual Murphy brand switches. The last one lasted three uses before failing, so I bought this one and hopefully it lasts a lifetime Review: perfect - Just as expected ## Features - CLOSED-LOOP WIRING COMPATIBILITY: Allows Swichgage and/or N.C. contacts to be wired in a "Closed Loop" (in series), where any open contact or closed Swichgage contact shunt trips the unit. - MANUAL INDICATING RESET: Operates as a 12-volt model featuring a convenient manual indicating reset type for quick status identification. - DUAL-FUNCTION OUTPUT CONTACTS: Equipped with NCH and NOH control circuit output contacts—providing a "hot" output on the NCH contact in the latched position and on the NOH contact in the tripped position. - RELIABLE ENGINE PROTECTION: Designed for distributor ignition or diesel engines with an energize-to-latch type, contacts rated for 10 amps at 24V, and a 14 amp fuse included. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07SF7GD57 | | Actuator Type | Push Button | | Best Sellers Rank | #163,202 in Automotive ( See Top 100 in Automotive ) #744 in Automotive Replacement Electrical Accessories | | Brand | Murphy by Enovation Controls | | Brand Name | Murphy by Enovation Controls | | Circuit Type | 1-way | | Color | Transparent | | Compatible Devices | Diesel engines, distributor ignition systems, engine control systems, Murphy by Enovation Controls devices designed for 518APH-12 compatibility | | Compatible with Vehicle Type | Trucks, Heavy Machinery, Marine Vehicles | | Connectivity Protocol | Wi-Fi | | Connector Type | Clamp | | Contact Material | Copper, Brass | | Contact Type | Normally Closed | | Control Method | Touch | | Control Type | ON-OFF | | Controller Type | touch | | Current Rating | 10 A | | Customer Reviews | 4.6 out of 5 stars 72 Reviews | | International Protection Rating | IP54 | | Manufacturer | Murphy by Enovation Controls | | Material Type | Brass, Copper | | Model | 518APH-12 | | Mounting Type | Panel Mount | | Number of Items | 1 | | Number of Positions | 1 | | Operating Voltage | 24 volts | | Operation Mode | ON-OFF | | Part Number | 518APH-12 Tattletale (25700147) | | Specification Met | Ul, Ip54 | | Switch Type | Closed Loop | | Terminal | Screw | | Unit Count | 1 Count | | Wattage | 240 watts | ## Product Details - **Brand:** Murphy by Enovation Controls - **Circuit Type:** 1-way - **Connector Type:** Clamp - **Contact Type:** Normally Closed - **Current Rating:** 10 A - **Material:** Brass, Copper - **Operating Voltage:** 24 volts - **Operation Mode:** ON-OFF - **Switch Type:** Closed Loop - **Terminal:** Screw ## Images ![518APH-12 Tattletale (25700147) - Image 1](https://m.media-amazon.com/images/I/71M3PfobCzL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great products *by M***T on April 24, 2026* I stopped buying the cheaper Chinese brand Murphy switches recently.
