Abstract

En trykkbryter omfatter et plasthus (1) hvor det er inn- støpt et tungerelé (2). Ved siden av tungereléet (2) er det i en fordypning på bryterhuset (1) anordnet en per- manentmagnet (3). En bevegelig bryterarm (4) svinger om en aksel (5) montert i bryterhuset (1) og heves ved hjelp av en fjær (6) som også låser akselen (5). En ned- ragende flik (10) på siden av bryterarmen (4) danner når bryteren mot fjærkraften ligger i anlegg på bryterhuset (1) en skjerm som skjermer tungreléet (2) mot magnetfeltet til magneten (3). Bryteren er i denne stilling av bryter- armen (4) åpen, og sluttes dersom bryterarmen ved hjelp av fjæren (4) heves en viss vinkel. En trykkbryter av denne art er særlig egnet som panser- eller alarmbryter i biler, men kan også inngå i serie med flere andre slike brytere i en alarmkrets. Fordelaktig er det da i parallell over tungreléet og likeledes i bryterhuset (1) anordnet en motstand (R). Slike brytere kan benyttes i både bilalarmer og husalarmer.A pressure switch comprises a plastic housing (1) where a tongue relay (2) is embedded. Next to the tongue relay (2), a permanent magnet (3) is arranged in a recess on the switch housing (1). A movable switch arm (4) swings about a shaft (5) mounted in the switch housing (1) and is raised by a spring (6) which also locks the shaft (5). A projecting flap (10) on the side of the switch arm (4) forms when the switch against the spring force rests on the switch housing (1) a screen which shields the tongue relay (2) against the magnetic field of the magnet (3). The switch is in this position of the switch arm (4) open, and closes if the switch arm is raised at a certain angle by means of the spring (4). A pressure switch of this kind is particularly suitable as an armor or alarm switch in cars, but can also be used in series with several other such switches in an alarm circuit. Advantageously, a resistor (R) is arranged in parallel over the tongue relay and also in the switch housing (1). Such switches can be used in both car alarms and house alarms.
