Abstract

The invention relates to a multipole switch operated by one finger. The switch comprises a multipole switch; the multipole switch consists of a master switch and a plurality of auxiliary switches; an operating handle is installed on the master switch; linkage handles are installed on all the auxiliary switches; all the linkage handles are connected with the operating handle, which is capable of driving motions of the linkage handles; and the operating handle and the linkage handles are connected with operating mechanisms in corresponded switches. Beneficial effects of the multipole switch provided in the invention are as follows: the operation is simple; closing is synchronized; locking is firm; the structure is simple; and production costs are reduced.

Description

technical field [0001] The invention relates to a single-finger operated multi-pole switch. technical background [0002] Single-pole switches and multi-pole switches can meet the needs of different lines. In the field of terminal electrical appliances, in order to meet the requirements of modularization and reduce the production cost of products, most multi-pole switches use multiple handles to form a linkage handle. to operate. In order to meet the requirements of preventing misoperation by others when the switch is not allowed to be switched on, some switches are currently equipped with a locking device to limit the operation of the switch. [0003] Electrical products generally do not have special requirements for the operation method, but since the operating parts of the current multi-polar products on the market are generally composed of multiple single-pole handles, the operating position is relatively wide, and it is inevitable that it will be used in different ope...
