A manually actuated switch includes a pair of terminals forming switch poles and a knob which is manually actuated to complete or interrupt an electrical circuit across the poles. A pair of spaced contacts are embedded in the knob and resiliently grip therebetween a diode which controls current direction of the completed circuit.
The invention relates to a manually actuated switch of miniature size wherein a circuit path is completed between poles of the switch by a contact having independent cantilever beams contacting a respective switch pole. The contact is carried by a manually displaceable sliding element in the form of a carriage. Movement of the carriage causes wiping of the cantilever beams over a substantial length of the switch poles. To interrupt the circuit the sliding element is moved to an extreme position whereby one of the beams is slidably traversed off a corresponding switch pole and into abutment against a dielectric projection which prevents chatter of the disengaged beam. Detenting action for precise positioning of the slider element is accomplished by sliding at least one of the cantilever beams over an irregular surface of one of the switch poles. To maximize cantilever beam length, each beam originates on one side of the slider element, projects diagonally across the free space under the slider element and slidably contacts a corresponding switch pole. Since the cantilever beams diagonally bridge across the entire length of the free space under the slider element the beams are of maximum permissible length assuring resiliency over a substantial range of deflection.
An electrical interconnection system comprises a main electrical bus to which branch electrical buses are electrically interconnected. The main bus and branch buses include a plurality of insulated electrical conductors extending crosswise to one another with electrical interconnectors electrically interconnecting selected electrical conductors of the buses together. The electrical interconnectors penetrate the insulation of the buses and make electrical connection with the electrical conductors. The terminated sections of the buses can be housed in housing assemblies providing strain relief and insulation. Shielding can be applied onto the main bus and ground connections can be effected at the housing assemblies.
An electrical plug connector comprises a dielectric contact-carrying member having signal contact members secured to one side of the contact-carrying member at spaced intervals therealong. A ground contact member is secured to the other of the contact carrying member with contact sections of the signal contact members and the ground contact member extending from a front end of the contact-carrying member. Conductor-connecting sections of the signal and ground contact members extending along the contact-carrying member. Signal conductors and ground conductors of electrical cables are electrically connected respectively to the conductor-connecting sections of the signal contact members and the ground contact member. A dielectric housing member is secured onto the contact-carrying member and part of the electrical cables so that the contact members from their contact sections to their conductor-connecting sections are covered. The signal and ground conductors are electrically connected to the signal contacts and the ground contact member respectively by first being force-fitted into respective slots thereof and then terminated by being laser welded thereto.

A DIP test socket is disclosed to provide a zero entry force receptacle for dual in-line packages. The receptacle comprises a transport block receiving a DIP package thereon, with rows of contact legs positioned to depend adjacent the sides of the transport block. A housing block is disclosed, loaded with dual parallel rows of contact members having upwardly directed spring finger portions receiving the transport block therebetween. The housing block is further adapted with camming means for influencing engagement between the DIP package contact legs and the contact spring finger portions as the transport block is inserted toward the housing block.
A double row connector is provided having an upper row and a lower row of a signal contacts with spring arm contact sections thereof projecting forwardly thereof from horizontal body sections of contact members. The contact members also have vertical body sections extending vertically from a side of the horizontal body sections and secured in vertical slots of a dielectric spacer block, and the horizontal body sections of upper contacts are disposed adjacent the upper surface of the spacer, and those of lower contacts are disposed adjacent the lower surface. Vertical body sections of the upper and lower contacts alternate along the spacer. The upper subassembly thus formed is secured to an upper surface of a planar insert having a ground plane secured to its lower surface, comprising a lower subassembly to form a contact assembly. Signal conductors of trilead cables are welded to ferrules of signal contacts, which ferrules extend rearwardly from the signal contacts beyond the spacer and are aligned adjacent the planar insert. Ground conductors are welded to the ground plane.

Abstract:
A miniature switch utilizes a flexible diaphragm which seals the switch. The diaphragm is compressed sealably against a cover by a spring biased inverted cup which compresses the diaphragm outwardly against the cover. The switch is actuated by pressing the diaphragm to displace the cup against the biasing action of the spring. The cup is conductive and bridges across poles of the switch to complete a momentary switch operation.
