Abstract: An electrical component, in particular a minature relay having fixed and movable contacts, is made from a lead frame (10) formed with a plurality of conductive fingers and on which is moulded an insulating base (32). Some of the fingers (64, 66) are bent downwards for connecting to a printed circuit board, while others (68, 70; 88 to 94) are bent up to form supports for the contacts (24, 26) or other structure. A second lead frame (34) may be laid orthogonally over the first lead frame for attaching spring arms (36, 38) to fingers (68, 70) before they are bent up.

Abstract: A switching device (Figures 5A 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: A solenoid includes a plunger (16) movable within a winding (12) between stable end positions in each of which it is held by permanent magnets (18, 20). In the form of a switching device (Figures 5A and 5B) the solenoid plunger (16) is engageable with an insulated lever (86) which in turn actuates a contact blade (76). 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.

Abstract: An electromagnetic device, in particular a solenoid contactor for controlling domestic electric heaters, comprises a frame (22), a double wound latching solenoid (18) surrounding a plunger (32), and a permanent magnet (20) which is disposed outside the winding at the end from which the plunger protrudes. The device may include a high current contactor (12) and a low current contactor, and may be operated by coded radio signals.
