    Abstract: A bistable switching arrangement has a magnetic system comprised of a yoke/core, an armature and at least one permanent magnet, as well as a magnetic coil. The armature is swingably held at the core by a spring and mechanically linked to a movable contact, with an air gap being formed in one switching state between the armature and a pole face of the yoke/core combination. In order to attain that only slight forces act upon the released armature, the permanent magnet is positioned in a region of the yoke to form one part of the cross sectional area, with the other part being formed by a non-magnetic member.

    Abstract: A switching device (FIGS. 5 A and 5B) employs as actuator a bistable solenoid which includes a plunger (16) movable within a winding (12) between end positions in each of which it is held by permanent magnets (18, 20). The plunger (16) of the actuator is engageable with an insulated lever (86) which in turn actuates a contact blade (76) via a spring (108). The lever may be cranked, and may have an extension (90) outside of the casing (70) to enable the device to be manually operated or to provide a visual indication of the state of the switch. Other types of solenoid may be employed as the actuator.

    Abstract: The invention relates to a polarized electromagnetic relay with magnetic latching and sliding armature.The magnetic circuit comprises a tubular frame enclosed by two flanges (22, 24), a permanent magnet (14) with axial magnetization fitted between one (22) of the flanges and a flux-diverter (26), and a cylindrical trip coil (30) mounted on a bushing inside the frame (20). The other flange (24) is fitted with a tubular sleeve (46) made of ferromagnetic material coaxially surrounding a part of the moving armature (16) with a uniform radial air gap (jl) interposed. The axial overlapping distance (L) of the armature (16) by the sleeve (46) in the latched position of the relay (10) is greater than the thickness (11) of the flange (24) and/or than that of the frame (20).

    Abstract: A detent hold and release mechanism on a manually positioned valve controller which electrically signals a servo controlled conventional hydraulic control valve. The mechanism has a detented operating position and a spring-returned neutral position when the detent is released; the detent is held in operating position by a locking pawl urged by a permanent magnet. The mechanism is released by energizing an electro-magnet positioned adjacent the permanent magnet with reverse polarity whereby the combined magnet forces are neutralized, thereby releasing the pawl and allowing the valve controller to return to the neutral position.
