Fixed screw, the fixed screw is rotated to adjust the height in fixed screw plane, so as to control the sinking of one-level push rod device
Highly.
Preferably, the movable contact component includes 2 groups of movable contacts, and the fixing terminal is arranged between 2 groups of movable contacts,
2 groups of movable contacts are separated, so as to ensure will not to be interfered with each other between 2 movable contacts.
Preferably, the stationary contact component also includes 2 groups of stationary contacts, glass is provided between 2 groups of stationary contacts, by 2
Group stationary contact separates, so as to ensure will not to be interfered with each other between 2 stationary contacts.
Preferably, the sheet metal on the stationary contact is arranged on the side of upper shell, and the sheet metal is provided with binding post, due to
Sheet metal is arranged on the side of upper shell, and electric wire can be directly connected on binding post, will not inside be surround, from without
The situation of line short.
Compared with prior art, the advantage of the invention is that：Patent structure of the present invention is simple, and upper and lower casing passes through screw
Connect, play dustproof and waterproof effect；Secondly can all be separated between dynamic and static contact by glass or fixing terminal, so as to
It ensure that the stability of elevator door contact switch；Furthermore because stationary contact is arranged on housing side, electric wire can be directly connected to connect
It on terminal, will not inside surround, from the situation without line short, ensure that security performance；Patent tool of the present invention
There are long lifespan, stable performance, and compact-sized, small volume, be adapted to large-scale promotion.
