The seat spaced with a plurality of receiving grooves, each groove is connected with two terminal receiving holes at the lower side thereof. The upper cover is spaced with a plurality of holes with respect to the receiving grooves on the seat, the upper cover covering on the top of the seat. A plurality of push buttons each having a push button seat. The top of the push button seat is installed with a protrusion which protrudes from the holes of the upper cover. The bottom of the push button seat has a convex pushing portion. The push buttons are matched with the push button seat on the receiving grooves of the seat. A plurality of terminal sets each including a first terminal and a second terminal. The first terminal and second terminal are fixed to the terminal receiving hole of the seat. Each of the first terminal and second terminal extending with two clamping portions. The upper ends of the first terminal and second terminal each extending with a contact portion. The contact portion of the first terminal is formed as a convex portion; and the contact portions of the first terminal and the second terminal are installed on the receiving grooves of the seat; the contact portion of the second terminal is formed below the contact portion of the first terminal. The pushing portion of the push button ejecting against the contacting portion of the first terminal. Therefore, an easily assembled and low manufacturing cost dial programming switch is formed by aforesaid structure.

An automatic-transmission control for outputting a switch signal of a shift position is produced as follows. A first terminal unit includes small-power fixed contacts coupled with small-power contacts of a connector through a coupling portion, is formed. A second terminal unit, which includes large-power fixed contacts coupled with large-power contacts of a connector through a coupling portion, is formed. A positioning resin block is formed to at least one of the first and second terminal units. The first and second terminal units are laminated through the positioning block. A switch body and a connector are molded upon inserting the laminated first and second terminal units in a molding die. The switch body and the connector are separated by cutting the coupling portion.

A fluid pressure responsive electric switch (10) is shown having an elongated base (12) in which first and second terminals (34, 48) are mounted by dropping them into respective slots (26, 28). The terminals are provided with tabs (38, 52) to engage with a platform (30) of the base to limit motion in one direction and are in turn engaged by a guide member (62) to prevent motion in an opposite direction. The guide member (62) has a cylindrical force transfer portion (86) aligned with the weld portion (104) of a sensor assembly (92) to transfer force without adversely affecting the calibration of the sensor assembly. Electrical leads (118, 120) have connectors (126, 128) attached to an end thereof along with cylindrical gaskets (134) which form an interference fit in bores (22, 20) of the base to provide an environmental seal at the same time electrical connection is made to the terminals. In a modified embodiment a special thermal isolation fitting (140) is shown particularly adapted for use in sealed refrigeration applications.

The object of the present invention is to enable a power source line and load to be connected in a single operation via a plug-in jack by operating a switch, and reliably support the bases of plugs while protecting the plugs with a plug cover formed into a single structure with a switch cover. In the present invention, a slide switch is described comprising: a knob facing to the outside from a slot continuous with a recess of an insulating base, movably providing a sliding body within the above-mentioned recess of the above-mentioned insulating base, arranging in parallel a plurality of fixed contacts that make sliding contact with a movable contact resiliently provided on the sliding body by means of a resilient spring, and covering its outside surface with an insulating plate; wherein, at least one of the above-mentioned fixed contacts is bent to compose a plug, and a guiding member, which guides the insertion of a plug-in jack J that attaches to the plugs, is formed into a single structure with the above-mentioned insulating plate.

The present invention is illustrated in one form as an inline electrical circuit breaker system for an electrical extension cable comprising an intermediate coupler having opposite end terminals adapted for electrically coupling a female terminal of a first electrical cable to a male terminal of a second electrical cable. A recess is formed in the coupler and has a pair of opposite end walls, the recess being adapted for receiving a circuit breaker. A first power bus segment extends from one of the opposite end terminals through an adjacent one of the opposite end walls and partially into the recess. A second power bus segment extends from another of the opposite end terminals through an adjacent one of the pair of opposite end walls and partially into the recess. The circuit breaker includes terminals for coupling the first and second power bus segments for establishing a current path through the coupler when the breaker is installed in the recess.

An electrical connector assembly has a threaded part having a conductor, an unthreaded part having a conductor, fittable along an axis with the threaded part for engagement of the conductors with each other, and formed with front and back axially spaced stops, and an internally threaded nut axially displaceable on the unthreaded part between the stops through a predetermined axial distance, rotatable about the axis on the unthreaded part, and threadedly engageable with the threaded part to lock the parts axially together with the nut engaging the front stop. The nut is formed with at least one axially extending and radially projecting tooth, the unthreaded part is formed with at least one axially extending and radially projecting tooth, and the teeth are so positioned that they come into engagement with each other only during a small fraction of the displacement of the nut on the unthreaded part immediately prior to engagement with the front stop.

摘要:
A rotary key switch has a momentary action such that a lock cylinder and control member are returned to normal positions by a torsion spring provided in a central bore of the control member. The switch housing is in two parts, a lower body portion and an upper panel mounted cap portion that also supports the lock cylinder. The lower portion defines a cylindrical cavity and supports the control member on a central post that is also provided in this central bore. The housing portions are telescopically secured to one another and a stop is deformed in part by the control member and the panel mounted cap portion to positively limit the rotation of the key and lock cylinder.
