Multigang switchgear

Abstract

The invention provides a multiple switch device capable of providing an excellent assemblability and a stable switching operation. This multiple switch device comprises an operating mechanism part 1 having a casing 2 and a plurality of operating bodies 3 to 6 held on the casing 2 movably in vertical direction and a switch mechanism part 14 having a plurality of switch elements 29 to 32 for performing a switching operation by the vertical movement of the operating bodies 3 to 6, a plurality of terminals 16 to 21 for connecting the plurality of switch elements 29 to 32 to external equipment, and a base stand 15 supporting the plurality of switch elements 29 to 32 and the plurality of terminals 16 to 21. The operating mechanism part 1 and the switch mechanism part 14 are formed separately from each other, and the base stand 15 is fixed to the inside of the casing 2 so that the operating mechanism part 1 can be formed integrally with the switch mechanism part 14.

Description

technical field [0001] The invention relates to a multi-connection switch device, in particular to a multi-connection switch device suitable for the operation part of a ventilation cover. Background technique [0002] Figure 5 It is a side view viewed from one side of a known multi-gang switchgear. As shown in this figure, in a box-shaped housing 41 with an open side, a plurality of operating bodies 42 and a reset operating body 43 are set, respectively, by means of the biasing force of the return spring 50. Its upper end protrudes from the opening 41a provided on the upper surface of the casing 41 at a certain interval and is held to move freely up and down, and a plurality of operating bodies 42 and a reset operating body 43 in the casing 41 are respectively provided with a support. Partition walls 45 with protrusions 44 and fixed contacts 46 made of sheet metal. [0003] And, in the housing 41, a joint flat plate 47 combined with the joint protrusions (not shown) forme...

Problems solved by technology

[0007] However, in the above-mentioned conventional multiple switch device, the bending portion of each movable contact 46 is inserted between the partition wall 45 and the supporting protrusion 44, and the movable contact 49 is installed in the case 41 by a plurality of operations. The operation in the slit between the body 42 and the partition wall 45 is extremely complicated, thus creating a problem that requires time spent on installation

[0008] And when carrying out this loading operation, because the upper and lower ends of the movable contact 49 hit the fixed contact 46 or the common terminal 48, etc., the bending angle of the movable contact 49 changes. Changes in the elasticity of the switch cause the switching action of the switching element to be unstable
