Abstract

The trigger has a thermal triggering device, pref. in the form of a thermobimetallic device (40), and an electromagnetic impact armature trigger with armature (33), coil (34), yoke and core. The yoke has an arm (35) parallel to the coil axis. The thermal trigger is attached to the arm and lies parallel to the coil axis and to the yoke arm so that it is heated by the current-carrying coil and yoke. The length of the arm corresp. to that of the thermobimetallic element; the former is pref. equal to in length or longer than the latter.
