Abstract

A switch in which the U-shaped slide actuator that is employed for each switching stage of the switch fits over the contacts of the switching stage so as to slide back and forth in order to operate the switching stage is disclosed. At each switching stage one of the leads is L-shaped with a contact area, while the other is L-shaped with an S-shaped contact section. In assembly of the switch, a plurality of such leads are formed on a single stamped sheet and the base of the switch is split into two halves, one half of which is molded over one set of leads; and the other half of which is molded over the other set of leads. The leads are then cut away from the remainder of the stamped sheets and the two halves of the base are secured together. A cover may be snapped onto the top of the switch so that automatic insertion equipment can pick up the switch by suction for automatic insertion of the leads of the switch into a printed circuit board.

1 SLIDE ACTUATED SWITCH BACKGROUND or THE INVENTION a minimum number of parts must be utilized. In aswitch constructed in accordance with the present in vention, the size of the switch may be maintained very small, although the switch of the present invention may be utilized for much larger applications, if desired. Small size is maintainable in the switch by usinga slide actuator, which except for a small extending actuating knob, is housed completely within the housing of the switch. Another factor that assists in maintaining reliability and keeping the size of the switch to a minimum is that the switch utilizes a simple protuberance on the slide actuator for operating the switch. In addition, no spring members are employed in the switch other than the leads.
' Although the design of the switch of the present invention may be utilized for a single switching stage, it is especially advantageous for use as a multiple-stage switch, especially in view of its construction which makes it adaptable to a novel method of assembly. In accordance with this assembly method, each pair of L- shaped leads are initially joined to a plate member on astamped sheet of metal. The base is split into two halves which are each molded over one set of leads. The leads are then cut and the two base halves are placed together and ultrasonically welded or secured by other means to form the completed base structure. A top housing member having apertures in it for guiding the slide actuating member back and forth which fits over the base member to complete the structure of the switch.
The switch disclosed herein is especially adapted for use on a printed circuit board program board for data processing equipment. This type of switch must be small in size and easily actuatable. The switch of the present invention fulfills these requirements. Although, automatic insertion equipment used to insert microcircuit components of similar size and shape into printed circuit boards is ineffective with switches of this type due to a large extent because of the air leakage path provided in the top of these switches around the sliding actuators. The switch of the present invention may be picked up and utilized with this equipment because of the addition of a snap-on cover which fits over the top of the switch.

Technical Description of the Invention Referringto FIG. 1, there is shown an electrical switch l0'constructed in accordance with the present invention that has a number of switching sections which are encased in the same housing 12. Each switching section of the switch 10 has a' resilient first lead 14 anda resilient second lead 16, the terminal ends of which extend from the base 18 and the upper ends of which form the contact areas for the particular switching stage. 'Also associated with each switching stage is a slide actuator 20 which has an actuating knob 22 that extends upwardly through an elongated aperture 24 in the top surface of a top housing member 28 for the switch.; Large size versions of the switch 10"of FIG. 1 may be actuated by hand; but if the switch is very small, it may be actuated by a driven operating member 30 that is shaped to fit in a small indentation 32 made in the to'p of the actuating knob 22.
The leads 14,16 are generally L-shaped and the lead 14 has a contact area 33 on its upper leg 34 while the lead 16 has a contact area 40 on its upper leg 36. The contact area 40 is actually a downward bend which, along with the upward bend 38, forms an S-shaped contact section. The contact area 40 contacts the contact area 33 of the lead 14 when the switch is closed. The slide actuator 20 has a general U-shaped configuration with sidewalls 20a and 20b that project over the legs 34,36 of the leads 14,16. The actuator 20 is thereby guided in its back and forth motion by the aperture 24 and by the legs 34,36. The actuation of the switch 10 is achieved by interaction of a downwardly projecting actuating member 42 formed on the slide 20 which contacts the'upward bend 38 to force the downward bend 40 into contact with the contact area 33 when the switch isclosed.
When the slide actuator 20 is positioned to the right, as shown in FIG. 2, the downwardly projecting actuating member 42is not in contact with the bend 38; and, therefore, the' normally open contact leads 14,16 are not closed. However, when the slide actuator 20 moves to the left, as shown in FIG. 3, the actuating member 42 comes into contact with the bend 38 forcing the contact leads 14, 16 together to close the switch. In order to cam the actuating member 42 downwardly when the slide actuator is moved toward the left, the upper surface 26 .of the housing member 28 is provided with a sloping wall 28 on its under portion, which engages a slight wedge 46 on the slide actuator 20.
A multiple-stage version of the described switch may be constructed by initially forming a plurality of lead sections 50 on a single stamped sheet metal member 48; with the base 18 being formed in two separate halves 18a, 18b, as shown in FIG. 5. The plurality of leads 14,16 are then bent downwardly, as shown in FIG. 6 and the base halves 18a, 18b are molded onto the leads 14, 16, respectively. The leads 14,16 are initially interconnected by the central plate 52 of the stamped member 48 and by the bars 54,56. As shown in-FlG. 6, the plate 52 andthe leads 14,16 then have a general overall'C-shaped configuration. Following molding of the base members 18a, 18b onto the leads 14, 16, the bars 54,56 are" removed and the plate 52 is severed along the lines 53,55 in order to separate the individual switching's'tages or sections of the. switch. When the leads 14,16 are molded into the base halves 18a, l8b, it is desirable that they be formed with enlarged sections 58,60 in order to firmly secure the leads into the base halves. 1
After the plate 52 and the bars54,56 have been severed, the basehalves 18a,: 18b are supported-on a support member- (notjshown) by the flat surfaces 62,64, with thelefthand edge 66 of the base half 18a being in contact with the righthand'edge 70 of the base half 18b so that the projection 68 on the base half 18b projects,

Many of these circuit packs are inserted by automatic insertion equipment into printed circuit boards by means of a vacuum pick-up More efficientfuse of a programmable switch 'of a similar size an d shape could, thus, be achieved if tion. The cover 80 has resilient legs 82,84 which contact the sides 83,85 of the switch and have feet 86,88 that grip the bottom 90 of the housing of the switch. The cover80 may abut the top surface 26 of the housing member 28, or it may have a shoulder 92 formed thereon to hold it slightly off the surface 26. Since vacuum pick will be achieved by suction applied to the top, preferably flat, surface 94 of the cover 80 opening provided at the ends of the switch by the shoulder 92 will prevent pick-up of the switch by a pick-up probe. Slot 96may' be provided approximately midway along the length of the legs 82,84 to increase the flexibility of the legs for easier snapping of the cover 80 on the switch 10, andalso to provide foreasier removal of said leads and in a second position of s'aidslide actuator is in contact with said second lead so as to force said second contact area into contact with said first contact area, an aperture in a surface of said housing, an actuating member on said slide actuator which projects through said aperture to allow for external actuation of said switch, a cover for covering said aperture in said surface of said housing so as to substantially seal off leakage air paths associated with said aperture when a suction pick-up means is placed adjacent said apertured surface having snap-on holding means for temporarily securing said cover on said switch which fits over the top of said switch and comprises a pair of resilient legs that contact the sides of the switch and which have feet that grip the bottom of the switch.
