Full Title
Full titles differ between systems:
Snap-action arrangements, i.e. in which during a single opening operation or a single closing operation energy is first stored and then released to produce or assist the contact movement > Energy stored by deformation of elastic members > by flexing of blade springs > blade spring with at least one snap-acting leg and at least one separate contact-carrying or contact-actuating leg
Snap-action arrangements, i.e. in which during a single opening operation or a single closing operation energy is first stored and then released to produce or assist the contact movement > Energy stored by deformation of elastic members (by deformation of bimetallic element in thermally-actuated switches H01H37/54) > by flexing of blade springs > blade spring with at least one snap-acting leg and at least one separate contact-carrying or contact-actuating leg
IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
