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.
Claims5
A mercury-wetted switch assembly, comprising:
- a housing;
- a baseplate inside the housing;
- a winding construction including a magnetic core mounted on the baseplate and having a pair of end flanges, and a winding wound directly around said core;
- a pair of mercury-wetted switch capsules mounted on the baseplate with one capsule being positioned on either side of the magnetic core, each capsule being insulated from each of the flanges of the magnetic core by insulating means;
- at least one of said capsules having at least one magnet externally positioned to the capsule;
- and
- each of said capsules having terminals connected directly to the capsule and projecting from the housing, whereby said terminals are physically independent from the winding construction.
