Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
169 words
A switch for use in controlling operation of a metal-air battery having air-depolarizable cells, means for housing the cells, and terminals connected to the cells, said switch comprising: wall means defining a vent opening for admitting air to the battery cells in the housing; a slide; means for guiding the slide for movement in a preselected path adjacent said wall means; electrical switch means constructed to be closed as a result of said slide being disposed in a first position in said path and open as a result of said slide being disposed in a second position in said path; means for connecting said switch means to the battery cell terminals; a flexible closure; and means for causing the closure to be sealed to said wall means across said vent opening when the slide is in said second position, and opening said vent opening and thereby permitting air flow through said vent opening as a result of movement of the slide from said second position to said first position.
Claim 2
Dependent Claim
169 words
A switch for use in controlling operation of a metal-air battery having air-depolarizable cells, means for housing the cells, and terminals connected to the cells, said switch comprising: wall means defining a vent opening for admitting air to the battery cells in the housing; a slide; means for guiding the slide for movement in a preselected path adjacent said wall means; electrical switch means constructed to be closed as a result of said slide being disposed in a first position in said path and open as a result of said slide being disposed in a second position in said path; means for connecting said switch means to the battery cell terminals; a flexible closure; and means for causing the closure to be sealed to said wall means across said vent opening when the slide is in said second position, and opening said vent opening and thereby permitting air flow through said vent opening as a result of movement of the slide from said second position to said first position.
Claim 3
Dependent Claim
23 words
The battery switch of claim 1 wherein said means for causing the closure to be sealed to said wall means comprises adhesive means.
Claim 4
Dependent Claim
29 words
The battery switch of claim 1 wherein said closure means comprises a flexible strip having one portion secured to said slide and another portion secured to said wall means.
