A tingling sensation just ran up your arm because you tried to unplug your coffee maker from the wall only to receive a shock. You were quite literally shocked since the outlet did not have a GFCI (Ground Fault Circuit Interrupter), or it was not functioning properly. GFCI breaker units detect an imbalance in the electrical current and shut down before that electricity reaches you or blows up the electrical device plugged into the outlet. A single unit monitors several outlets in one section of the house. For example, you may have one breaker for the bedroom and one for the kitchen. When a breaker shuts off, you simply switch it back on. They each have a maximum amperage rating, so first find out how many amps you need for the area. For example, a 20 amp GFCI breaker cannot handle as many outlets or as much power usage as a 50 amp unit can. You can find several kinds on eBay and make your home a safer place for everyone.
