This switching element for an electrical energy distribution board comprises a distribution bar and a support plate on which the distribution bar is fixed. The switching element comprises a coil, a contact movable under the action of the coil, said contact being mounted movably in a chamber. Said chamber comprises two parts intended to be mounted on the distribution board (P) in such a way that the movable contact acts on said bar, said chamber being furnished with means of fixing to the distribution bar or to the plate, the switching element being non-removably fixed by said chamber onto the distribution board (P).

Examples relate to a compressible housing. An electronic switch may include a circuit board. A first conductive surface may be coupled to the circuit board and a second conductive surface may be located proximate to the first conductive surface. A compressible spacer may be located between the first conductive surface and the second conductive surface to space the first conductive surface away from the second conductive surface. Further, a compressible housing may deform when under compression and may cause, via deformation of the compressible spacer, the first conductive surface to contact the second conductive surface.

Further disclosed is a method for producing an SMD-solderable component.

A modular auxiliary switch includes a housing including a first housing part and a separate second housing part secured to the first housing part. A printed circuit board is housed in one of the first and second housing parts, and has a first side facing the first housing part and a second opposite side facing the second housing part. An actuator mechanism is housed in the first housing part and is coupled to the printed circuit board. A separate first electrical contactor is selectively mounted to the printed circuit board so that a first electrical contact surface of the first electrical contactor overlaps and is in direct contact with one of the first side and the second side to define a first electrical contact pad on the printed circuit board.

A roller electric contact comprises a roller comprising a shaft and a plurality of conductive discs electrically separated by an insulating material. The shaft extends through a rotational axis of the roller. A housing comprises slots in which the shaft of the roller is positioned, the slots configured to direct a non-rotational movement of the roller. A plurality of leaf springs are disposed in the housing. The leaf springs comprise an electrically conductive material. The plurality of conductive discs are spaced on the roller so that at least one of the conductive discs contact each of the plurality of leaf springs. A plurality of conductive wires extend from the roller electric contact, each of the plurality of conductive wires making electrical contact with one of the leaf springs.

A resin structure includes a molded resin element and a push-type switch. The push-type switch includes a receptacle whereon a first terminal and a second terminal are secured, the first terminal and the second terminal configured to connect to an electrical circuit; a button unit protruding from the receptacle; and a contact spring unit configured to move with the button unit, to electrically connect between the first terminal and the second terminal, and to generate an opposing force relative to a pressure applied between the receptacle and the button unit. The receptacle stores the button unit and the contact spring unit. The receptacle of the push-type switch is embedded in the molded resin element with the button unit exposed from the molded resin element.

An electromagnetic relay includes: a housing including a base and a case that opens downward and is provided on the base, the housing having an internal space surrounded by the base and the case; a main fixed contact; a main moving contact that comes into contact with and separates from the main fixed contact; an auxiliary fixed contact; an auxiliary moving contact that comes into contact with and separates from the auxiliary fixed contact; a coil provided in the housing such that a central axis extends in a vertical direction; an iron core disposed so as to be surrounded by the coil; a yoke disposed around the coil; an armature that is disposed to face an upper end of the iron core and swings in response to excitation/non-excitation of the coil; a movable part provided with the main moving contact and configured to move in response to swinging of the armature; and a partition wall that divides the internal space of the housing into a first space and a second space.
