Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
140 words
A pushbutton switch comprising: a housing; an elongated slider arranged to move in the housing along a substantially straight axis; contact bridge means on the slider; contacts mounted in the housing for cooperation with the contact bridge means; removable stop means extending through an opening in the housing into the slider in a direction generally perpendicular to the axis in order to locate the slider in at least one particular position along its axis of movement; and a helical spring which has an axis parallel to the axis of movement of the slider and normally at least partially surrounds the stop means to retain the latter in operative position, the helical spring being capable of being compressed for uncovering the stop means and permitting removal of the stop means from the slider in a direction generally perpendicular to the axes.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
46 words
A switch in accordance with claim 1 in which the stop comprises a generally U-shaped part with two generally parallel limbs and a crosspiece connecting the limbs, the crosspiece having a spring engaging surface which makes an angle with the axis of movement of the slider.
Claim 4
Dependent Claim
29 words
A switch in accordance with claim 2 in which the spring engaging face of the U-shaped part makes an acute angle with the axis of movement of the slider.
Claim 5
Dependent Claim
36 words
A switch in accordance with claim 2 in which one limb of the U-shaped part fits in a hole in the housing and acts as a pivot and extends into a longitudinal groove in the slider.
Claim 6
Dependent Claim
38 words
A switch in accordance with claim 4 with a detent slot beside the groove in the slider, one limb of the U-shaped part being capable of being selectively fitted in the slot or in the travel limiting groove.
Claim 7
Dependent Claim
67 words
A switch in accordance with claim 2 in which a detent slot and a travel limiting groove are provided in the slider, the switch further comprising two such U-shaped parts which may be fitted selectively in position so that one limb of the one U-shaped part fits into the deTent slot or the one limb of the other such U-shaped part fits into the travel limiting groove.
Claim 8
Dependent Claim
33 words
A switch in accordance with claim 6 in which the slot and the travel limiting groove are placed one behind the other in the direction of the axis of movement of the slider.
Claim 9
Dependent Claim
64 words
A switch in accordance with claim 2 comprising a coalescing travel limiting groove and a detent slot in the slider, the switch comprising two such U-shaped parts which may be fitted selectively in position so that one limb of the one U-shaped part fits into the detent slot or the one limb of the other such U-shaped part fits into the travel limiting groove.
Claim 10
Dependent Claim
38 words
A switch in accordance with claim 2 in which tee spring engaging face on the U-shaped part is substantially perpendicular to the axis of movement of the slider and is formed by a step in the U-shaped part.
Claim 11
Dependent Claim
29 words
A switch in accordance with claim 1 in which the helical spring surrounds the slider, ends at a position adjacent to the pushbutton, and serves to load the pushbutton.
Claim 12
Dependent Claim
