ABSTRACT:
A hermetically sealed relay of the reed-type in which an elongated switching control rod is angularly displaced in operation. The extreme positions include internal stops, which may be contacts, in which case the switch is a single-pole-double-throw device. An attached actuator for the switch device provides tolerance-absorbing overtravel by means of uniquely arranged resilient means, such that switch-gap tolerances are effectively absorbed. The device may be of the magnetically latching type or may, in simplest form, include a single controlling electromagnet and only one fixed contact. Two embodiments are described.
