A hybrid dimming controller for a lighting control system providing isolated class 1 and class 2 dimming outputs. The controller has two NEC class 1 outputs for providing independent low-voltage dimming-control signals for two lighting loads and two NEC class 2 outputs for providing the same two independent dimming control-signals for the lighting loads. Thus, the controller has both a class 1 and a class 2 outputs for delivering the same dimming-control signal for each of the two lighting loads while maintaining within the controller the isolation that is required between class 1 and class 2 circuits.

A heavy-duty plug-in connector has a ground terminal that can be conveniently assembled and can comprise the greatest possible number of electrical crimp plug-in contacts (4,5). For this purpose, ground plug-in contacts (4′, 5′), likewise of a crimping configuration, are fitted in formations (13, 13′, 23, 23′) of the contact carriers (1, 2) for electrical contacting with metallic protective earthing elements (3, 3′, 3″, 3″). For said contacting, the formations (13, 13′, 23, 23′) have a respective opening (130, 130′) or passage (230, 230′). In the formations (13, 13′, 23, 23′), not only ground plug-in contacts (4′, 5′) but also further plug-in contacts (4, 5) are arranged, so that the number of plug-in contacts (4, 5) of the plug-in connector is increased considerably.

An electrical connector assembly includes: a housing having a base, a body extending rearward from the base, and a hole through the base and the body, the hole including a first part of a first diameter, a second part of a second diameter greater than the first diameter, and a step portion between the first part and the second part; a connector received by the housing, the connector having an insulating member, an inner conductor, and an outer conductor received by the first part of the hole, the outer conductor having plural tabs received by the second part of the hole; and a metal plate confining the tabs to the second part of the hole.

An electrical power tap connector for a model vehicle is provided including a first power tap housing. The first power tap housing contains a power tap terminal configured to electrically couple with a connector terminal of an electrical connector. The power tap connector also includes a second power tap housing releasably securable to the first power tap housing and a releasable locking mechanism configured to physically secure the power tap connector to the electrical connector. Wherein the power tap terminal is configured to electrically couple with the connector terminal via a non-mating end of the electrical connector.

A metal shell-less receptacle connector includes a ceramic module, a glass seal having an insertion hole into which an outer circumferential portion of the ceramic module is fitted, and a ceramic support having a seal fastening hole into which an outer circumferential portion of the glass seal is fitted and fastening holes to which fasteners are fastened. Contacts and a ceramic material are integrated, whereby high data transmission is enabled due to impedance optimization and low loss characteristics, heat dissipation performance is improved due to high thermal conductivity, and durability is improved due to high strength. The shell-less structure reduces frequency interference, thereby improving the performance of an antenna positioned adjacent to the connector. The glass seal improves waterproof performance. The connector is connected to a main board using an FPCB, thereby improving the degree of freedom of position. A simple assembly structure promotes mass production, thereby reducing cost.
