Abstract

The device has a thermal trigger, esp. with a thermal bimetal, that disengages a switch lock latching point via a sliding element (16) movably guided in the switch. An adjustment screw (22) mounted on the sliding element enables setting of the distance between the sliding element and the trigger (15) on the one hand and between the sliding element and a trigger lever (12) interacting with the latching point on the other hand.
