Abstract
A pushbutton actuated excess current switch with thermal tripping by a bimetal strip and with trip-free release. The pushbutton includes a component incorporating an actuating rod, a connecting bridge and a stud pointing away from the actuating rod and having an annular groove for receiving one end of a disconnecting spring the other end of which is supported in a switch housing, this component being unitarily made of synthetic material. Furthermore a threaded sleeve inserted into the switch housing and serving for guiding the pushbutton or the actuating rod as well as for affixing the switch housing is unitarily produced from synthetic material. The use of such unitarily produced components simplifies the manufacture of the switch.
