Claims

[Scope of Claim for Utility Model Registration]' 1. The upper support insulator is provided with a fixed contact, and the lower support insulator is provided with a movable contact that can move toward and away from the fixed contact. A current-limiting fuse is connected to the current-limiting fuse, and a locking member for inserting and holding the movable contact against the spring force of a release spring is connected to the fusing indicator that protrudes when the current-limiting fuse is blown, via a connecting rod. In a pneumatic switch with a granulated fuse that can be drawn out, the upper and lower supporting insulators are fixed to a base provided at one location, and the connecting rod is connected so that one end thereof is connected to the tip of the lower supporting insulator. 1. A pneumatic switch with a current-limiting fuse, characterized in that it is disposed at a position corresponding to between the upper and lower support insulators so as to be attached to a part of the fuse holder provided. 2. The current limiting fuse according to claim 1 of the utility model registration claim, wherein the base is formed in a mountain shape, and the upper and lower support insulators are attached to the base so as to form a V-shape. Attention switch.
