Timer Interconnection System TE Connectivity's (TE) Timer Interconnect System features contacts used extensively in the automotive industry. Each contact of this TE series consists of a flat receptacle, which mates with a flat tab. The receptacle has two respective four contact springs, which are independent of each other. Two-piece contacts with a steel top spring are predominantly. This two-piece contact design means that the electrical and mechanical properties are separated. One end of the contact body is either crimped to wire or soldered to a printed circuit board. The other end of the contact body mates with the matching tab.
