Abstract

The invention provides an auxiliary switch, which mainly solves the problems that a connection mechanism can be adjusted only by opening an upper cover and use is very inconvenient due to the fact that a binding post of an existing auxiliary switch is provided with the upper cover therein. The auxiliary switch is characterized in that a connection structure (3) which is electrically connected with a static contact patch board (11) for connection is arranged on the outer wall of the upper cover (2). According to the auxiliary switch provided by the invention, a conducting post is arranged on the outer wall of the upper cover, so that the connection structure can be adjusted without opening the upper cover; and the auxiliary switch is convenient to use and convenient to maintain.

Description

technical field [0001] The invention belongs to the field of switches, in particular to an auxiliary switch. Background technique [0002] Auxiliary switch is a part of the main switch. It is configured in power equipment such as vacuum circuit breakers and isolating switches as the opening, closing, signal control and interlock protection of the secondary control circuit. It can also be used as combination switch and transfer switch. use. The reason why the auxiliary switch has the word "auxiliary" in its name is because it is not an independent switch, it is a carrier for the realization of auxiliary breaking, making and interlocking functions in the control system. [0003] The wiring post of the existing auxiliary switch is generally provided with the inside of the upper cover, so when adjusting the wiring mechanism, the upper cover needs to be opened to adjust, which is very inconvenient to use. SUMMARY OF THE INVENTION [0004] In order to overcome the deficiencies...
