Abstract

Connector for a reed switch comprises a cylindrical connector body having two stamped and formed contact members thereon. One of the contact members has a wire receiving slot adjacent to a first end of the switch body for one of the switch leads. The other contact member has a wire receiving slot adjacent to the second end for the other switch lead. Both contact members have slots for external conductors at the first end. An inserter is slidably mounted on the first end for pushing external conductors into the slots which receive the external conductors. The switch body has excess lead storage portions at each end for storing portions of the leads which extend beyond the lead wire slots. A housing encloses the switch body and has an opening through which the inserter projects.
