H01H 5/06

by compression or extension of coil springs

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

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 compression or extension of coil springs

CPC:

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 compression or extension of coil springs

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.
