Abstract
Viene proposto un apparecchio elettrico (10), preferibilmente un apparecchio interruttore con componenti elettrici (11) su una piastra portante (12), che è chiusa a tenuta in una cassa (14) per mezzo di una massa di resina colata (19), che è applicata dall'esterno sulla piastra portante (12) e arriva fino al bordo 18 della cassa. Per compensare variazioni dimensionali, dipendenti dalla temperatura, fra piastra portante (12) e cassa (14) la piastra portante (12) nella propria zona marginale (12a) è dotata di un agente di separazione (20a); repulsivo per la resina colata, per formare una zona di dilatazione elastica X nella massa (19) di resina colata (fig. 2b).
