  • Patent number: 4217474
    Abstract: A simplified linkage and cam member having first and second cam surfaces for interacting with a bail to drive said bail between first and second limits is provided. The cam surfaces restrict the movement of the bail when the bail is at either limit. However, when the bail is intermediate of the limits, the relationship of the effective portions of the cam surfaces allow increased bail movement for a given position of the cam member and associated cam surfaces. The structure is particularly well adapted for actuating a bail from a first to a second position wherein forces other than those applied by the cam also act on the bail; and at a critical bail position, the other forces take control and urge continued motion of the bail independent of the cam member.

This actuator means is shown as a lever which acts on an actuable portion of a contact blade or directly moves a contact portion into and out of engagement with an individual contact. For economy the actuator means lever may be unitary with a housing by means of a unitary hinge which not only permits movement of the lever but also provides a resilient force in first and second generally perpendicular directions. This resilient force is used to establish the contacts in a closed circuit condition and is also resisted by a detent so that the switch remains in that selected circuit condition. When the switching mechanism is constructed as a multiple pole switch, then a common conductor is provided which has individual contact portions actuated by a plurality of levers for an economically produced switch.

  • Patent number: 4052580
    Abstract: A momentary contact push switch comprising a thin terminal board having spaced stationary contacts on a narrow intermediate region thereof. A bridging contact is positioned on the underside of a unitary plastic housing member. The housing member includes integral yieldable side skirts that extend downwardly from opposite sides and below opposite side edges of the intermediate region of the terminal board. Inwardly extending barbs or latch elements on the bottoms of both side skirts snap under the edges of the terminal board and hold the housing on the terminal board. Spring means extending between the terminal board and the bridging contact hold the bridging contact and housing member above the stationary contacts. A downward force on the housing member overcomes the spring force and brings the bridging contact into contact with spaced stationary contacts.
