<p>The invention concerns a switching apparatus advantageously providing a better distribution of forces for pull-in and tripping forces, requiring reduced manoeuvring force, providing high-current circulation sections for limited space requirement. Said switching apparatus (1) is characterised in that each switching module (10) comprises for each fixed contact (4, 4'), two symmetrical mobile contacts (6, 7) arranged on either side of the fixed contact, each mobile contact (6, 7) is associated with a spring (62, 72) and coupled to a slide (63, 73) mobile in translation. The control module (11) comprises a control shaft (14) passing through the switching modules (10) and bearing cams (16, 17) co-operating with each slide (63, 73). Said cams (16, 17) are designed to move simultaneously the two mobile contacts (6, 7) of each fixed contact (4, 4') between a pulled-in position and a tripped position. The invention is applicable to any industrial electrical installation.</p> |
