H01H1/50 - CPC Classification

Classification description:

Contacts Means for increasing contact pressure, preventing vibration of contacts, holding contacts together after engagement, or biasing contacts to the open position

Sub-classes:

H01H1/502 » {the action of the contact pressure spring becoming active only after engagement of the contacts} 13
H01H1/504 » {by thermal means} 14
H01H1/52 » Contacts adapted to act as latches 15
H01H1/54 » by magnetic force 100
H01H2001/506 » {Fail safe contacts, i.e. the contacts being kept in a safe position, usually in an open circuit position, at end of life time of switch} 10
H01H2001/508 » {with mechanical means to prevent return/reverse movement of movable contact once opening or closing cycle has started} 7
