an isolating switch

Abstract

A disconnect switch. Oval receiving grooves (111, 121) are respectively provided at corresponding positions of a base (11) and an upper housing (12) of the disconnect switch. A protruding column (31) is separately provided on both sides of a movable contact carrier (3). The movable contact carrier (3) is movably disposed in the oval receiving grooves (111, 121) by means of the protruding columns (31). A spring (6) or / and a tension spring (7) is provided between the movable contact carrier (3) and the base (11). One end of the spring (6) or / and one end of the tension spring (7) acts on the base (11) and the other end acts on the movable contact carrier (3). The point of action of the spring (6) or / and the tension spring (7) on the movable contact carrier (3) is located above the protruding column (31) and near the protruding column (31). The disconnect switch overcomes the shortcomings in the prior art, and provides a novel disconnect switch which is easy to operate and high in closing and opening speed and has an indication function.

Description

technical field [0001] The invention relates to a switch, in particular to an isolating switch. Background technique [0002] The existing isolating switch structure is a multi-contact isolating switch. A plurality of moving contacts move up and down linearly under the direct drive of the handle and the connecting rod to realize the separation and contact of the dynamic and the static, thereby realizing the closing and opening of the isolating switch. The product has some shortcomings: 1. The use of precious metals is large, the production cost is high, and the reliability is also reduced due to the large number of contacts; 2. There is no quick closing device, and the closing speed of the product depends on the speed of the human-operated handle. It is beneficial to the electrical life of the product; 3. There is no arc strike pin, the arc stays between the dynamic and static contacts for a long time, and the contacts of the product are easily burned during the opening and ...
