Abstract
"Battery Switch"
Abstract A switch (11) for use in controlling operation of a metal-air battery (10). The switch includes a slide (21) guided for reciprocal movement in a preselected path adjacent a wall (18) defining a vent opening (19). The switch includes contacts (25,26,31,27,32,28) providing a closed electrical circuit as a result of the slide being disposed in a first position and providing an opened electrical circuit as a result of the slide being disposed in a second position. In the second position, the vent opening (19) is sealingly closed by a flexible closure strip (35) having one portion (37) adhesively bonded to the slide and a second portion (39) adhesively bonded to the wall portion (18) defining the vent opening.
The strip is arranged to be selectively peeled from the slide bottom surface (38) and wall portion surface (40) and readhered to the opposite surface as a result of the selective movement of the slide in effecting the opening and closing of the vent opening.

Patent ~,262,062, Norman Zatsky discloses a metal-air battery having an internal gas permeable membrane for restricting the transfer of oxygen from the ambient atmosphere to the battery cathode. This structure utilizes an internal valve actuated by an external force on the cell to open the valve and admit substantial quantities of oxygen for intermittent high current drain on the cell. The external force is provided by the same switching device which closes the electric circuit re~uiring the high current drain.

-~- M-POR-7801 Best Mode for Carr~in~ Out the Invention __________________ __ ________________ _ In the illustrative embodiment of the invention as disclosed in the drawing, a metal-air battery generally designated 10 is provided with a switch generally designated 11 mounted to a housing 12 of the battery. The switch includes a finger manipulating portion 13 for selectively disposing the switch in electrically opened and closed switching conditions, while correspondingly selectively preventing and permitting air flow to the battery cells 1~ within the housing 12.
As best seen in Figure 2, switch 11 includes a switch housing generally designated 15, including a base portion 16 and a cover portion 17. Base portion 16 is defined by a wall portion 18 defining a vent opening 19. As seen in Figure 4, vent opening 19 may be aligned with an opening 20 in the battery housing 12 for selectively permitting air flow from the ambient atmosphere to the cells 14.
Switch 11 further includes a slide 21 which is reciprocable along a rectilinear path defined by sidewalls 22 and 23 of the base portion 15 of switch housing 15. Cover 17 is provided with a through opening 2~ through which the finger manipulating thumbpiece 13 extends for engagement by the user's fingers.
On its upper surface, slide 21 is provided with a pair of movable contacts 25 and 26. The fixed contacts of the switch are defined by a first pair of spring finger eontacts 27 and 28 extending through one end wall 29 of cover 17 for connection to cell terminals 30 of the battery.
The fixed contact means further includes a second pair of spring finger contacts 3~ and 32 projecting outwardly through the opposite end wall 33 of the cover.
~Zl~t7~
-5~ L'O~-7801 As seen in Figule 2, th~ spring fingel - contacts are provided with distal rorrned portions 34 arrallged so that the contact portions 3~ of spring finger contacts 32 and 28 are bridged by movable contact 26 and forme(] portions 3~ of sprin~ fir~ger contacts 31 nnd 27 are bridged by movable contact 25 when the switch is in the electrically closed condition, as shown in Figure 3.
The invention comprehends the provision of a novel closure means for selectively closing the vent opening 19. As illustrated in ~igure 2, the closure generally designated 35 comprises a strip of flexible material, SUCll as Mylar* synthetic resin, having an adhesive coating 36 on one face thereof. As shown, tlle strip is folded to define a first portion 37 which is adhesively bonded to the undersurface 38 of slide 21, and a second portion 39 which is adhesively bonded to the upper surface 40 of wall portion 18.
Thus when the switch is in the "off"
condition, wherein the moving contacts 25 and 26 are spaced from the fixed contacts 31,27 and 32,28, the righthand end of strip portion 37 has been peeled from the slide undersurface 38 and underturned into adhesive engagement with the wall portion 18 defining the vent opening 19 so as to effectively sealingly close the vent opening.
As can be seen in Figure 4, at this time, portions 37 and 39 of strip 35 are effectively facially abutted, being urged together by the slide 21 to effectively provide a positive closing of the vent opening 19.
~ Yhen the rnanipulating portion 13 is urged to the left from the position of Figure 4 to the position of Figure 3, wherein the movable switch contacts 25, 26 are in switch-closed relationship with the fixed * Mylar is a trade mark ,; .

-6- M-P~R-7801 contacts 31,32 and 27,~8, the righthand end of strip portion 37 is peeled from the wall surface 40 of base 16 and adhesively secured to the undersurface 38 of slide 21 so as to expose vent opening 19 for providing communication between the ambient atmosphere and the interior of the battery housing 12.
As seen in ~igure 3, in the closed condition of the switch, the sprin~ finger contacts urge slide 21 downwardly to maintain firm adhesive engagement between the slide and strip portion 37 and strip portion 39 and base surface 40.
Industrial A_plicability ____________ ________ The improved switch 11 may be utili~ed in a wide range of industrial applieations in controlling the electrical connection and air vent means of metal-air batteries, such as ~inc-air batteries and the like.
The switch may be installed directly on the battery housing for use of the housing as a base for the switch.
Terminals 31 and 32 of the switch may be connected to the external appliance as desired.
The improved metal-air battery switch of the present invention is extremely simple and economical oE
construction while yet providing improved positive control of the air vent opening in a novel and simple manner.
The foregoing disclosure of specific embodiments is illustrative of the broad inventive concepts comprehended by the invention.
In one form, the closure means comprises a flexible strip of synthetic resin, such as Mylar~
