Abstract

1304920 Current responsive thermal switches ROBERT BOSCH GmbH 16 Dec 1970 [19 Dec 1969] 59617/70 Heading H1N An overcurrent cut-out for an electric motor or like has a one piece bimetal strip with two arms 21, 23, one of which (23) is of smaller crosssection and shorter than the other, the smaller arm being arranged to urge a contact 18 towards a fixed contact 26 upon increase in temperature while the larger arm urges the contacts apart.
