Abstract: A switch assembly comprising a housing including a baseplate on which are mounted a magnetic core having a pair of flanges and a winding wound around it, and two switch capsules positioned on either sides of the magnetic core with each capsule being insulated from each flange of the magnetic core by insulating means. Magnets are also positioned to provide either a monostable or a bistable mode of operation as desired. With this constructions, the magnetic and electric paths in the assembly are physically separate from one another, thereby allowing the magnetic and electric materials to be chosen independently from each other.

Abstract: A reed contact relay comprising within a capsule, reeds the coacting tips of which are provided with spots made of a material which can not be wetted with mercury. Two tubes in magnetic material are aligned in spaced apart relation around the reeds such that an axial gap is formed therebetween at the lenghtwise level of the coacting tips of the reeds. The inner wall of these tubes and the surface of the reeds, except the surface of the spots, are wetted with mercury.
