In Fig. 1 a window installation of an embodiment according to the present invention is shown. One Locking lock switch construction 30 is used for locking the lower sliding window 32 of a window arrangement 54,

The lock lock holder assembly 30 is attached to a window frame 36 in which the lower sash 32 slides. In the particular embodiment shown, the locking lock-bchalter-Anorclaun.g 30 is also arranged at a point at which the lower sliding window 32 and an upper sliding window overlap when both sliding windows are in the in / ir ,. 1 are in the fully 'closed position \

.iflg. Figure 2 shows the general construction of the lock switch assembly 30 in detail, -i'ie also from fig. 2, the device consists of an anchorage-steep 40 attached to the window frame 36, and a locking bolt housing 42 which is embedded in a corner recess of the anchoring part 40 · The housing and the anchoring member 40 are dimensioned so that when they are assembled, their outer surfaces abut one another and offer the image of a single compact block.

The housing 42 wears a socket 44, which is transverse to Direction of movement of the lower sliding window 32 runs. When the lower sliding window 32 is open and moving down in the vertical direction, the extends

.7-109816 /0033

called hole through the housing 42 horizontally to the lower sash window 32. A cylinder lock 46 fits exactly in the lock hole 44 of the housing 42 * There is also a key-operated lock cylinder 48 which extends into the lock 46 and on the front of the lock 46 has a slot 50 for a key.

From Fig. 3 it can be seen that the anchoring part 40 consists of a relatively thin splash section 50 and a stronger switch housing section 52, which protrudes from the splash section. The flange section has several fastening holes 54 through which screws or bolts for fastening the anchoring part 40 = can walk on the window frame 36. Ss will it should be noted that the holes 54 are completely covered by the locking bolt housing 42 when the device is fully assembled.

The switch housing section 52 of the anchoring part is provided with a recess 56 which follows outside in a curses that open with the outside surface of the flange portion 50 matches. An electrical switch 58 is inserted into the recess 56. The switch 58 contains an actuation button

and a flexible leaf spring switch 62 »which is located extends over the push button 60 * The switching arm 62 protrudes normally up without touching the push button 60. By the influence of the locking bolt housing 42 it is pressed down against the push button 60 when the locking bolt housing is in its normal or not operated position, which is in the Pig. 2 and 3 is shown. -ie Pig too. 3 shows, there is an opening 64 at the end of the locking bolt housing 42 smaller diameter present, which is opposite the sliding window 32 and in the yet to be described Veise allows the locking bar to be pushed out.

As the sectional view of Fig. 4 shows, is the anchoring part 40 attached so that its splash portion 50 rests flat on the window frame 36, namely the front of the sliding window 32 opposite. With this type of fastening, the switch recess 56 covered by the window frame 36, at the same time the Fastening openings 54 covered by the locking bolt housing 42. As a result, neither the switch nor the mounting screws are accessible to unauthorized singing.

As FIG. 4 further shows, the lock bore 44 is in the locking bar housing 42 after the front end of the housing

open minded. The bore 44 extends through the housing up to a point almost on the opposite snout Housing, but a thin -and 66 remains at this opposite end of the housing. The locking bolt opening goes through this end wall 66 64 and establishes a connection with the lock bore 44.

You can see there? the lock 46, which is exactly in the Lock bore 44 fits, is significantly shorter in the longitudinal direction than the bore 44 and is therefore in '' ipp.:r hole can move back and forth »Las inner The end of the lock 46 is provided with a cylindrical locking bolt 68 which is connected to the locking bolt opening flees. As a result, when the locking lock 46 moves back and forth in the lock bore 44, the locking bolt 68 pass the bore 64 ". <Which will be described in detail later, are means of holding on of the lock 46 is provided in the inner position shown. The locking bolt 68 is thereby in held in the position in which it protrudes from the housing and engages in dos lower sliding window 32.

The lower sliding window 32 is provided with a Hiegelaiifnehiasr which has a tubular oil transducer

housing 70 extends all the way through bore 72 and is on the opposite side of the sash window 32 open. In the housing 70 there is another spring-loaded bio-gel part 74, which is normally is held completely in the housing 70. However, if the seal 68 protrudes into the housing 70, he displaces the bolt 74 and moves it against the

upper sliding window 38. The upper sliding window 38 is also with its own bolt receiver housing 76 provided, which flohtet with the bolt 74 when the upper and lower sash windows are completely closed position. This protrudes when the spur bolt operated by a key -58 to the Locking the lower sliding window 32 advanced into the housing 70 in its closed position fc, also the bolt 74 from the lower sliding window into the bolt receiver housing 76 in the upper sliding window 38, so that this sliding window is also locked in its closed position.

The construction of the bolt receiver housing 72 in The lower sliding window 32 can best be seen in FIG. 5, as shown here, the bolt 74 has in the Area of the level switch device 30 a section 78 of larger diameter. This "larger diameter" portion 78 is in contact with the locking bar 68 of the bolt switch device 30 »

The housing 70 itself is provided with a longitudinal slot in the area of the wider section 78. By the longitudinal slot 80 is a small guide screw in the enlarged diameter portion 78 of the bolt

screwed so that its head protrudes into the slot 80. The screw 82 allows the Latch 74 by a length which corresponds approximately to the length of the slot 80. Between section 78 with A compression spring 84 encloses the larger diameter and a wall 85 at the inner end of the housing 70 Latch 74. Spring 84 normally holds latch 74 in the retracted position shown in FIG. When the seal 68 is out of the bolt switch assembly 30 ™

is advanced into the housing 70, it strikes the enlarged diameter portion 78 of the bolt 74 and moves it to the left (see Fig. 5). As a result, the bolt 74 is in the housing 76 in the lower sliding window 3.8 pushed, whereby the upper sliding window 38 and the lower sliding window 32 locked together while the lower sliding window 32 is locked to the window frame 36 via the bolt switch arrangement 30 is. I.

As FIG. 5 shows, the bolt housing 42 is provided with a longitudinal slot 90 which extends outward from the lock bore 44 to the surface resting on the flange section 50 of the anchoring part 40. A small lead screw 92 goes through the slot 90 and is screwed into the lock 46. With axial movements of the

. _13th 109816/0033

Lock 46 in its bore 44, the head of the guide screw 92 in the slot 90 is moved back and forth. As a result, the lead screw 92 limits the size of the Longitudinal movement that the lock 46 can perform in the housing 42. The position and length of the slot 90 are chosen so that that the lock 46 moves from a first position in which its outer surface with the outer surface of the housing aligns and the Riegql 68 is completely withdrawn, like fe this is shown in FIG. 2, can be moved into a second position in which the lock 46 is located in the housing 42 and its locking bolt 68 projects completely into the housing 70 of the lower sliding window 32, as in FIG. 4 is shown.

How to get out of the exploded view of Fig. 6 recognizes, the Megel housing 42 is provided with a projection 94 which is inserted into a recess 96 in the Switch housing portion 52 of the anchor member fits. A force adjustment screw 98 goes up through the Lütte of the recess 96 and is screwed into the projection 94 of the Hiegelgehäuses 42 to this at his To keep space on the anchoring part 40. As FIG. Also shows, the resilient leaf spring switch arm 62 also goes up through the upper surface of the Section 52 and meets in a designated

-H- 108816/0033

Recess 100 on the housing 42. enn the housing rests flat on the top of the switch housing section, presses the surface of the recess 100 downwards onto the switch arm 62, but the housing 42 is moved away from the surface of the switch housing section 52 is lifted off, the Sehaltarmt62 can be raised move, whereby the switch 58 is actuated.

From Fig. 7 it can be seen that the switch housing section 52 of the anchoring part 40 is provided with a pin bore which is aligned with a point in the vicinity of the lower end of the recess 96 and extends up to this point. The pin bore 102 and the recess 96 are connected via the screw opening 104 through which the force adjustment screw 98 passes. A spring 10G that responds to the force surrounds the force adjusting screw 98 between its head and the opening 1C4 in the switch housing section 52 of the anchoring part 40. The spring 106 serves to pull the head of the force adjusting screw 98 downward, as described in Pig. 7 can be seen, whereby the bolt housing 42 presses down on the surface of the holder housing section. However, ^r Yenn the Megel is advanced 68 and a force for lifting the sliding window is applied to the top 32, causes this force upward,

-15- 109816/0033

that the housing 42 lifts against the "Virkung of responding to the force of spring 106 from the switch housing section 52 ^u. hen this occurs, the shift arm is as already described, 62 moves upward and thereby actuates the switch 58th It can be seen that by turning the force adjusting screw 98, the distance between the head of the screw and the opening 104 can be adjusted in order to thereby change the tension of the spring 106 W and to be able to adjust the magnitude of the force required to actuate the switch 53.

7 further shows, the lock 44 is in its outer position (the locking bolt 68 is completely withdrawn) by one or more lock springs 110 pressed, which is between the housing end wall 66 and the lock 46 extend. The springs 110 are guided by support struts 112 attached to the '.' / And 66 of the ^ Housing 42 are directed against the lock 46, 'töenn the lock 46 is moved inward to push out the bolt 68, the struts 112 protrude inward Bores 114 which are provided in the lock 46.

The housing 42 is additionally provided with a snap-fit bore 116 provided, which in the inner wall surface of the lock bore 44 goes. The catch hole 116 is

109816/0033

brings that it can work together with a snapper attachment 118 in the lock 46 "This snapper attachment 118 is pressed outward by springs (not shown) and can be withdrawn by turning a key inserted into the key cylinder 48," the shooting 44 is located in the Tig. 7, the latch boss 118 is held in its upper or retracted position by the inner surface of the lock bore 44. However, when the lock 46 is advanced so that its bolt 68 protrudes as shown in FIG the latch attachment 118 to lie opposite the latch bore 116 penetrates the bore and holds the lock 46 against the action of the lock springs 110 in its inner position. The device remains in this locked state until the latch attachment 118 is lifted out of the latch bore 116 by turning a key. \

When the above-described arrangement is operated, there is no effect whatsoever on the upper sash window 38 still exercised on the lower sliding window 32, when the bolt switch device 30 is in its non-locking position. The sliding windows can be opened individually or together at will or

getting closed. The locking of the sliding window is effected simply by pressing the lock 46 with the thumb or finger of the locking bolt 68 in the housing 70 is pushed in the lower sliding window 32. When this is the case, the additional protrudes Locking bolt 74 in the housing 76 of the upper sliding window 38, whereby the two sliding windows together and the lower sash window 32 via the bolt switch device 30 can be locked to the window frame 36.

In addition, the device is automatically held in the locked state, since the snapper attachment 118 in the Snap hole 116 of the latch housing 42 occurs.

When an attempt is made to forcibly open the lower sliding window 32, a force is applied via the latch 68 ) exercised the housing 42, which tries to lift this up from the anchoring part 40, which is on the window frame 36 is attached. This upward force is to some extent due to the on the Force responsive spring 106 "/ drag glides. If however, the resistance of the spring 106 is overcome, the housing 42 is removed from the switch housing portion of the anchor plate 40 lift slightly so that the switch

arm 62 can move away from the switch lower part 60 and thereby the electrical switch 58 is actuated. Of the electrical switch 58 is not shown outer coat for remote triggering of an alarm in conjunction.

The arrangement described above can be applied to the surfaces of the window and door frame with a minimum

make constructive changes. Still it is ^

impossible, although the arrangement is mounted on the outer surface, to close the interlock or the switch eliminate it or switch it off in some other way without that an alarm is triggered. For example, any attempt to disengage the lock by loosening bolt 98, which holds the fierel housing 42 on the anchoring part 40, for actuating the electrical switch 58 and thus trigger the alarm.

In Fig. 9 is the locking Alarni device 200 on top of a lower sliding window 202 in close proximity to one

- ¹⁹ "

109816/0033

Side or edge 204 of an upper sliding window 206 is milled. The lock alarm device 200 includes an anchor plate 208 that is attached to the lower sash window 202 and an outer enclosure 210 that fits onto the anchor plate 208. At one end of the outer encapsulation 210, a lock bore 212 runs in the horizontal direction and contains a lock 214 similar to the lock 46 according to the previous exemplary embodiment *. An acoustic alarm transmitter 216 is mounted on the outer encapsulation 210 in order to transmit the locally generated alarm tone. Just-. if present, there are a pair of tension adjustment screws 218 that can be turned down to adjust the amount of force required to trigger an alarm.

As Fig. 10 shows, the lock 214 is with a lock bolt 220 is provided, which, when the lock 214 is fully pushed in, into a bolt receiver 222 of the Slider 204 of the upper sliding window 206 protrudes, whereby the two sliding windows 206 and 202 are effective are locked together.

From Fig. 11 it can be seen that the clamping screws 218 extend through the outer encapsulation 210 and into the

- ^{? n} - 109816/0033

anchor plate 208 are screwed. On the action of force Responsive springs 224 enclose the screws 218 between their braid and the lower surface 226 of the Outer enclosure 210. For lifting the outer enclosure 210 of the anchor plate 208, it is thus necessary to compress the force-responsive springs 224. The amount of force required for this lift-off depends on how far the tensioning screws are 218 are screwed in, as this is the size of the force -f

determine up to which the springs 224 withstand the upward movement of the outer enclosure 210.

From Figs. 11 and 12 it can be seen that when trying to forcefully move the upper sash window 206 down or the lower sash window 202 up, a reaction force between the locking bar 220 and the recess 222, in which it engages, is generated, whereby a Tilting effect on the outer enclosure 210 | the locking alarm device 200 opposite the anchoring plate 208 is exercised. It can also be seen that, when this tilting process takes place, a blocking surface 230 assigned to the outer encapsulation 210 is lifted from a shoulder 232 assigned to the anchoring plate 208. If this is the case, a switching process takes place ^,! that triggers the alarm. Details of the switching process are described in detail below.

- ²¹ "

109816/0033

As can be seen in FIG. 13, the outer encapsulation is in principle a hollow structure in which an electrically operated alarm generator 234 is attached directly below the alarm transmitter 216. The alarm generator can be an electrical siren such as that disclosed in U.S. Patent Application Serial No. 530 883 filed March 1, 1966, or an ordinary electric horn. The alarm generator 234 receives a positive ψ potential via a wire 236 which leads through a bushing 238 in a battery holder 240. The battery holder 240 is made of a synthetic fiber material, plastic or other insulating material and holds one or more batteries 242 or corresponding electrical energy sources. The positive terminal of the battery 242 is held in contact with a spring-like contact element 244 which is connected to the bushing 238 and thus produces the positive connection to the electrical alarm generator 234. The negative or ground connection of the electrical alarm generator 234 is established through the outer encapsulation 210 made of metal or another conductive material. As can be seen from FIG. 13, however, the negative terminal of the battery 242 is kept separated from the outer enclosure 210 by an insulated button 246 on the rear of the battery holder 240. The entire battery holder 240

-22- 109818/0033

is by a lug 232. which is assigned to the anchoring part 208, and is attached to the rear blocking surface 230 of the battery holder 240 is located, printed forward. At the same time one tries in the following spring arrangement described in more detail to push the battery holder 240 backwards.

If the outer encapsulation 210 is pressed upwards as a result of an attempt to press or break into the ski window 204 or 206, the outer encapsulation 210 is lifted slightly from the anchoring plate 208 against the effect of the force-responsive springs 224. This lifts itself up The rear surface 230 of the battery holder 240 moves away from the shoulder 232 on the anchor plate 208. As a result, a biasing or pushing arrangement, to be described below, moves the entire battery holder 240 to the rearward position shown in Figure 14, thereby contacting the negative end of the battery with an inner {

Shoulder 248 in the saw on the rear side of the external encapsulation 210. As a result, the electrical circuit for viewing the battery 242 and the alarm generator 234 is closed and an acoustic alarm signal is emitted via the alarm transmitter 216.

- 23 -

109816/0033

It should be noted that the approach 232 on a leaf spring 250 is attached so that after the cessation of the pushing or breaking force that the Sounding of the alarm triggered, the battery holder 240 presses down on the extension 232, but through the Approach contact with shoulder 248 is not broken. This will keep the alarm state as long as possible maintained until the battery holder 240 is moved back "to v ^ rn, whereby the connection with the Shoulder 248 is interrupted and the approach 232 behind the back 230 of the battery holder 240 can move back up.

The spring pressure arrangement attempting to push the battery holder 240 rearward is shown in FIG. 15 and 16 shown. As these figures show, the battery holder 242 has laterally protruding lugs 250 provided on each side. These approaches can align with the battery holder 240 in length moving recesses 252 of the outer encapsulation 210 back and forth. Run in the recesses 252 two guide struts 254 which are connected to the outer encapsulation at the front end of these recesses and go through (not shown) openings in the seats to guide the lugs during their longitudinal movement

to support. Cylinder springs 256 surround the guide struts 254 between the front end of the recess 252 and the lug 250 and try to pull the lugs and the battery holder 240 backwards to press.

As has already been stated, the mode of operation of the lock 214 and the locking bolt 220 during locking corresponds to that of the embodiment according to FIGS. 1 to 8. In the present embodiment, however, the lock 214 also has a reset function. This is achieved by a recess 260 on one side of the key 214 (FIGS. 16 through 16). This recess is equipped with a tapered control surface 262 at the end on the bolt side. In addition, the rear end wall 230 of the battery holder 240 fits into the recess 260 when the battery holder 240 is supported by the compression springs 256 in the in a

14 and 16 is pushed to the rear position when, on the other hand, the lock 214 is in the 15 is the non-locking position shown, the control surface 262 of the recess 260 acts on the Rear wall 230 of the battery holder 240 and pushes the battery holder 240 into its foremost position. If the Battery holder has reached this foremost position,

109816/0033

the extension 232 goes under the action of the leaf spring to redden and latches the battery holder 240 in the foremost position. By pressing in the locking lock 214, the two sliding windows 202 and 206 can then be locked with one another, with the bolt 220 protruding into the bolt recess 222. The lock 214 goes up to a position in which the recess 260 with the barrier wall ψ 230 of the battery holder 240 is at the same height. If the outer encapsulation 210 is now raised, the battery holder 240 can move backwards after releasing it from the extension 232 under the action of the compression springs 256, so that the back of the battery 242 touches the shoulder 248 of the outer encapsulation 210 and the circuit between the battery 242 and the alarm generator 234 closes, so that an alarm is triggered.

. The disassembled representation according to FIG. 17 shows the actual construction details of the outer enclosure 210 and the anchoring plate 208 in more detail. You can see an elongated leaf spring 264, which is attached at one end to the top of the anchor plate 208 and which is normally protrudes upwards against the underside of the battery holder 240, thereby placing the battery holder 240 in the top External encapsulation to keep 2IO.

As a result, when the enclosure 210 is moved upward, the spring 264 can hold the battery holder 240 with the enclosure move upwards so that it can release the approach.

'Tie can also be seen from FIG. 17 are located on the anchoring plate 208 two upwardly projecting Vor sprün. ^ E 266. Bio so Vor projections are threaded and take the tensioning screws 218 through the encapsulation 210 g ^ hen. The clamping screws 218 thereby enable the encapsulation 210 to be moved up and down, at the same time a certain degree of encapsulation effect so that it cannot move sideways. At the opposite end of the anchor plate 208 there are two upwardly projecting lugs 268 which engage in guide openings 270 in the encapsulation 210 and support the mentioned leadership.

•• ^r ie Fig. 17 shows, the anchoring plate 208 is fixed by screws 272 on the upper side of the sliding window. Ivlan recognizes that when the audio encapsulation is in place on top of the anchor plate 208, the mounting screws 272 are visible and that these screws are only accessible when the encapsulation 210 is removed.

19 to 23 show an embodiment of the invention suitable for use on casement or bottom hung windows. The casement window shown in FIG. 19 can be pivoted away from the window frame 302 in the direction of arrow A. The window frame 302 includes a window sill 304 along ί the bottom of the window 300. A latch switch assembly 306 is assembled with the window 300, the window frame 302, and the window sill 304. The deadbolt switch assembly 306 includes a deadbolt enclosure 308 that is mounted on the edge of the window 300 and a stop plate 310 that is inserted into the window sill 304. It can be seen from Fig. 19,

-29- 10981S / 0033

BUILDING

that with the window closed 300 the Kiegelkapseiung is directly above the stop plate 310 *

As FIG. 20 shows, the locking bolt encapsulation 308 is included equipped with a vertical hole 310 ^ in which a lock 312 fits exactly. The lock 312 can be press down into the bore 310 so that a bolt, not shown, in a bolt opening 314 of the Stop plate assembly 310 engages * The stop plate assembly 310 itself has a cylindrical shape Lower housing 316 that is in a corresponding opening finds its place in the window sill 304. As the figure also shows, sits on top of the cylindrical housing 316 a flat flange portion 318 that cuts flush with the surface of the window sill 304. Of the Flange portion 318 is provided with a plurality of mounting holes 320 that can be used for screws or others Fastening means for attaching the arrangement 310 to the window sill 304 are intended.

From Fig. 21 it can be seen that the locking bolt encapsulation has two countersunk mounting holes 322 through which the mounting screws or bolts 324 are used to secure the Encapsulation 308 at the edge of the window 300 go «Two access holes 326 are with the mounting holes 322 directly

^"30 ~ 109818/0033

aligned on the other side of the bore 310. The access holes 322 permit the use of a screwdriver or some other tool for securing bolts 324 or other retention means in place. In this connection it can be seen that, when the lock 312 is in the bore 310, it is thereby at least the Boreich between one of the access holes 326 and the associated mounting hole 322 is covered. When the lock 312 is inserted, this can be done Do not remove latch housing 308 from window 300.

The locking lock 312 has a locking bolt 328 which goes from the lower end through a bolt opening 330 at the bottom of the locking bolt housing 308 when the locking lock 312 is in the rig. 21 is depressed position shown. When the locking catch 312 is withdrawn, however, as FIG. 20 shows, the locking bolt 328 is completely withdrawn into the housing 308. An Ä

Locking cylinder 332, which is through the locking lock 312 is provided with a normal keyhole 334 (see Fig. 20) for rotating the lock cylinder in the Lock lock 312 provided. The rotation of the lock cylinder 332 causes a lateral locking lug 336 to be withdrawn into the locking lock 312. The locking lug 336 becomes elastic in the protruding position

according to FIG. 12 held. ^T "7enn the Sperrschljß in the lowermost position shown 21 is shown in Fig., The blocking projection 336 projects downward in an existing in the bore 310 recess 338. It serves the locking block 312 as shown in FIG. Lowermost position shown 21 or Maintain the locked position.

When the lock 312 is in the locked position 21, the bolt protrudes downwardly into the opening 314 of the stop plate assembly 310. As a result, the locking bolt housing 308 and thus also the window are fixed on stop plate assembly 310, locking window 300 to window sill 304.

The stop plate arrangement 310 serves not only to "anchor the bolt 328" and also to monitor any Force exerted on the window 300, which moves the locking bolt in the opening direction of the window strive. For this purpose, the stop plate arrangement is in the cylindrical housing 316 a slide 340 is provided. As FIG. 22 shows, the slider 340 can be in the horizontal direction in to move back and forth on a Kanal342. The channel 342 is cut diametrically through a guide block 344,

-32- 109816/0033

which fits exactly into the cylindrical housing 316. That Slider 340 has a bore 346 that supports the latch. 328 fits exactly when it comes out of the case is pushed out.

The slide 340 is guided in its to-and-fro movement in the channel 342 of the guide block 344. It can be seen that the Gleitstückbohrung 345 while reciprocating right under the opening 314 of the stop plate assembly 310, and the like

moved here. The opening 314 is in turn elongated pulled to allow slight back and forth movement of latch 328 when onto window 300 a force is exerted in the direction of arrow A (FIG. 19). During this movement, the slider 340 is the Clearance B (Pig. 20) between a Sante of the bore 346 and the slider 340 and one end of the elongated Slit 314 in the stop plate assembly 310 overcome. This movement of the slider a 340 counteracts a compression spring 350 between the slide and the inner surface of the cylindrical housing 316 is attached.

Thus, due to the arrangement described above, the window 300 can only be moved in the opening direction if the acting force with the locking padlock locked

101816 * 0033

arrangement 306 can overcome the resistance of the spring 350. After overcoming the force of the spring 350 can move the window only the distance B, whereupon the bolt 328 touches the end of the elongated hole 314 and this prevents further movement.

According to FIG. 22, the slider 340 is equipped with an upwardly projecting shoulder 351. This approach ψ meets an arm 352 of an electrical switch 354, which is attached to the underside of the guide piece 344. The extension 351 can move back and forth in a slot provided at the bottom of the guide block 344-.

Referring now to FIG. 23 covering _s seen from the one that the spring 350 urges the slider 340 in such a direction that the projection 351 to Sehaltarm 352 is moved so that he of a pushbutton 358

Switch 354 presses. The switch arm 352 consists of elastic material, for example fiber steel, and does not normally rest against the push button 358. the The force of the spring 350 by far exceeds the restoring force of the switching arm 352 and thereby pushes it against the switch push button 358. If; however, push or break in forces exerted on the window 300,
