Abstract

Inventia se refera la un întrerupator automat de scara ce foloseste un burduf de cauciuc, din care prin apasare pe butonul întrerupatorului se elimina aerul printr-o supapa la sfarsitul cursei butonului fiind actionat un microîntrerupator care comanda aprinderea corpurilor de iluminat umplerea burdufului cu aer facandu-se printr-un ventil tip ac, în final se comanda microîntrerupatorul în sens contrar pentru întreruperea circuitului de iluminat. The invention relates to an automatic ladder switch using a rubber bellows, whereby by pressing the switch of the switch the air is removed by a valve at the end of the button stroke by means of a microswitch which controls the lighting of the luminaires filling the bellows with air, by means of a needle valve, the microswitch is finally commanded in the opposite direction for switching off the lighting circuit.
