Abstract

The modular electrical apparatus contact lock prevention has a moving contact (4) with a contact carrier (5) connected to a command handle (M) pivoting between two positions. There is a rotating command in which the pivot is commanded simultaneously with the moving contact in rotation, acting during the closure contact operation. A handle is operated during opening, If a solder contact loss occurs the handle is blocked in an intermediate position between the two positions, obscuring holes in the lateral ears.
