Abstract (en)
[origin: US4562418A] An electromagnetically operated electric switch has its movable contact system attached in a contact carrier, which via rotatable arms is connected to two identical magnetic cores of an operating magnet. Both magnetic cores move along a line perpendicular to the contact movement, towards each other upon closing and away from each other upon opening. The cores are suspended from the stand of the electric switch by means of leaf springs which control the movement of the cores. The leaf springs may also serve as opening springs.
