An electrical outlet, such as a cigar-lighter type socket in a vehicle, has a conductive socket well 1, an insulating connector housing 11 adjacent the transverse distal end of the socket well, and two electrical terminals 12, 13. A fuse member 8D may be provided, which may be an SMT fuse on a PCB 8. The electrical outlet is also preferably provided with integral over-temperature protection, comprising a spring-loaded leaf spring 6 impinging on a thermoplastic disc 7 that softens at a threshold temperature, allowing the leaf spring to penetrate through the disc and short-circuit the electrical supply.
