Description
Technical field
The present invention relates to electric elements, and in particular to a kind of elevator limit switch.
Background technology
There are following technical problems for existing limit switch：The moving component of switch it is exposed in working environment, in electricity
In sub- enterprise's electroplating industry, scene has serious corrosive gas, damages switch block.And existing limit switch makes
Declined with the power performance that a period of time rear limit switch switchs, the button of final Taoist priest's switch is insensitive, it is therefore desirable to seek
A kind of technical solution solves such technical problem.
Invention content
The present invention provides a kind of elevator limit switch, this limit switch has acid-resistant property, and this switch is dynamic
Power performance significantly improves.
The present invention provides following technical proposals：A kind of elevator limit switch, which is characterized in that the elevator limit
Switch includes switch case 1, threaded cap 2, spring 3, slide core 4, automatic screw 5, switch cover 6, rubber washer 7, inserts 8, mandril
9, lever 10, rubber sleeve 11, push jack 12, flat spring component 13, wiring gasket 14, static contact 15, bridge contact component 16, institute are pressed
It states threaded cap 2 and screws lid with the switch case 1 and connect, the slide core 4 is equipped with the spring 3, and 3 one end of the spring is opened with described
It closes shell 1 to be fixedly connected, 9 one end of the mandril is fixedly connected with described by lever 10, and the rubber sleeve 11 coats the mandril
9, the other end of the mandril 9 is fixedly connected with the slide core 4, and the slide core 4 is fixedly connected with the bridge contact component 16,
1 inner wall of the switch case is fixedly connected with the static contact 15, the static contact 15 under 3 squeezing action of spring with the bridge
Formula contact component 16 crimps, and one end of the mandril 9 is equipped with push jack 12, flat spring component 13, the inserts 8, wiring gasket 14
The static contact 15 is installed.
Beneficial effects of the present invention are as follows：This bridge contact component 16 is in normally off with the static contact 15 first,
