In response to TE Connectivity issuing end-of-life for high current relays to optimize current product offerings, Chief approached EGIS Mobile to create a drop-in replacement to fill a need in the market.

Certain applications require a specific type of relay, as different amperage and current ratings can change the current flow and also hamper device performance.
