A push switch includes an electrically insulating cylindrical base defining an interior space in which an actuator is movably disposed. Fixed contacts are associated with the base, while an inverted V-shaped contact is carried by the actuator so as to be capable of coming into contact with the fixed contacts and thereby making and breaking an associated electrical circuit. The base includes stepped detents which coact with terminal engagement ends associated with elastically deformable engagement legs of the actuator so as to limit the actuator's extent of movement. A resilient protective cap collectively covers an upper region of the insulating base and the actuator and is coupled to the base by a pin formed on the base being engaged within a recess formed in the cap.

Waterproof and dustproof push switch

Connector assemblies for mounting electrical components and for establishing electrical connection with the same are provided with a support base which defines an engaging hole to accept a connector subassembly. The connector subassembly includes an electrically insulating base member, and a pair of U-shaped resilient electrical connectors which are adapted to support an electrical component as well as establish electrical communication therewith. The support base and the connector subassembly are collectively provided with structures which allow the insulating base member to be inserted into the engaging hole of the support base to achieve a coupled position and such that, upon reaching this coupled position, the insulating base member is coupled to the support base.

Connector assembly for electrical components

A slide switch includes a slide body having a movable electrical contact. An insulating housing for the sliding body is formed in a substantially inverted U-shape and is provided with a slot to allow a knob to project therethrough and thus permit the sliding body to be manually manipulated. The housing also includes a number of projecting pins which are received within respective holes formed in a bottom insulating plate to provide connection between the housing and the plate. At least one pair of elongate conductive contact plates extend transversely relative to movements of the slide body (and hence relative to movements of the movable contact). Each of the conductive contact plates defines an aperture at one end thereof through which a respective one of the projecting pins of the housing passes before entering a respective one of the holes defined in the insulating plate. In this manner, the pair of contact plates are positioned within the housing and are, moreover, captured between the housing and the plate. Movement of the slide body, and hence the movable electrical contact, relative to the pair captured contact plates thereby makes and breaks an electrical circuit.
