Abstract: Electromechanical relay constructions comprise an external housing, a pair of switchable electrical contacts disposed within the housing, an element for activating the pair of electrical contacts, and a temperature sensing element disposed within the housing adjacent the electrical contracts. The temperature sensing element provides a signal for determining the temperature within the relay housing. The relay may comprise two or more temperature sensing elements disposed within the housing a desired distance from one another. The temperature sensing element may be attached to a member or substrate disposed within the housing, may be attached to an existing internal structure of the housing, or may be attached to one of the contacts. The temperature sensing element may be selected from the group consisting of resistance temperature detectors, negative temperature coefficient thermistors, thermopile sensors, thermocouples, and combinations thereof.

Abstract: The electrical connector assembly for field terminable connections includes a housing, switch assembly, at least one open channel, at least one insulated wire, and removable cover. Switch assembly is arranged and disposed within housing and includes at least one contact. At least one open channel is disposed within housing and aligned with at least one contact. At least one insulated wire includes insulation layer and conductive core and is arranged and disposed within at least one open channel and is adjacent to at least one contact. Removable cover for housing includes at least one protrusion arranged and disposed to cooperate with at least one open channel, at least one contact and at least one insulated wire. Securing removable cover with housing causes protrusion to penetrate insulation layer on at least one insulated wire to form electrical contact between the respective conductive core and the respective contact.
