Product Overview
Relay-Matic 5D1C-1019 Ice Cube Relay with 8 Pin Plug-In Base and Clear Cover
Condition
New. The relay is photographed bare in hand, with no socket, clip, or packaging shown. The clear plastic cover is intact and carries the Relay-Matic name molded into the side, with the internal mechanism fully visible through it: a wound coil bobbin, blue and white coil lead wires, a spring-return armature, white insulator posts, and the contact assembly. The black round base carries eight plug-in pins, straight and bright with no bent tips or socket scoring visible. Four slotted screws sit at the corners of the metal base flange. Both return springs and the plated collars and washers above and below the two white ceramic insulator posts show orange-brown granular surface patina in the photographs, so judge the surface condition from the photos. Body markings for coil voltage and contact rating are not legible in these photos.

Product Overview
This is a Relay-Matic 5D1C-1019 general purpose ice cube relay, stocked at PartsMine as part number CC18057. It is the classic plug-in style: eight pins on a round base that drops into a matching relay socket, with the entire electromechanical works sealed under a clear cover instead of the usual opaque shell. Through that cover you can see exactly what you are buying, which is unusual for a control relay and genuinely useful when you are matching an original part in an older panel or explaining relay operation to someone at a bench. Coil voltage, contact rating, and contact arrangement are not confirmed in the source listing and are not legible in the photographs, so treat this as an identified part by brand and number rather than by electrical specification, and verify against the relay's own markings and your socket pinout before you wire it in. Three pieces are in stock and the photographs show one representative unit.

Frequently Asked Questions
What coil voltage does this relay use?
Not confirmed. No coil voltage is stated in our records and none is legible in the photographs. Check the markings on the relay body and confirm against the 5D1C-1019 data before applying coil power.
How many contact sets does the eight pin base give me?
Not confirmed for this unit. The photographs show an eight pin round plug-in base, but we cannot read a contact arrangement off the part, so verify the pinout against your socket and the relay's own data before wiring.
Does a socket or hold-down clip come with it?
No. The photographs show the relay by itself, and that is what ships. Sockets and hold-down clips are separate items.
Why is the cover clear instead of the usual solid plastic?
That is how this Relay-Matic is built. The practical benefit is that you can inspect the armature, spring, and contacts before and after installation without opening anything, which is handy for troubleshooting and for teaching.
I only need one or two relays for a panel. Do I have to buy a lot of ten?
Not here. Three pieces are in stock and you take the count you actually need, whether that is one relay for a single socket or all three so the drawer has spares. That is the difference from a bulk auction lot, where you buy fifty to get the two you were after and store the rest for years. Shipping is $8 flat rate and free once your order passes $28, and orders leave our Idaho warehouse the same or next business day.
Most relays hide their work behind a wall of gray plastic; this Relay-Matic puts the armature, the spring, and the contacts out where you can watch them close. Drop it back into a control panel or set it on a bench to show somebody how a relay actually makes up its mind, and the next chapter is yours.
