Abstract
The invention relates to an improved pressure switch, which comprises a casing, a returning diaphragm, a ceramic top rod, a baffle plate, a connection sheet and a connection contact, wherein the returning diaphragm is arranged in the casing, the top of the ceramic top rod passes through the baffle plate to be connected with the connection sheet, the bottom of the ceramic top rod is in contact with the returning diaphragm, the top of the connection sheet is provided with a reset spring, the reset spring is fixedly arranged in the casing through a regulation screw, the connection contact is arranged above the connection sheet, in addition, gaps are left between the connection contact and the contact sheet, a sealed pressure chamber is formed between the returning diaphragm and the casing, and the bottom of the casing is provided with a pressure passage communicated with the pressure chamber. The improved pressure switch is characterized in that a stainless steel sheet is arranged outside a contact point. The improved pressure switch has the advantages that the rusting cannot be easily caused, the service life is long, and the switch precision and the sensitivity are high.
Description
Technical field
The present invention relates to a kind of switch, specifically, relate to a kind of improved pressure switch.
Background technology
Pressure switch generally is divided into normally closed switch and normal open switch.The contact contact that no matter is normally closed switch or normal open switch can produce spark when sheet contacts with connecting; This damage to the contact contact is bigger; Time one, length was easy to get rusty, and the precision of causes switch and sensitivity reduce, and have shortened the useful life of pressure switch greatly.Therefore, need a kind of new technical scheme to solve above-mentioned technical problem.
Summary of the invention
The purpose of this invention is to provide a kind of improved pressure switch, this switch long service life, be difficult for getting rusty, switch precision and sensitivity are strong.
The technical scheme that the present invention adopts is:
A kind of improved pressure switch comprises housing, return diaphragm, ceramic push rod, baffle plate, connection sheet and make contact, and said return diaphragm places in the housing; The top of said ceramic push rod is passed baffle plate and is connected with the connection sheet; The bottom of said ceramic push rod contacts with the return diaphragm, and the top of said connection sheet is provided with back-moving spring, and this back-moving spring is fixed in the housing through adjustment screw; Said make contact place the top of connecting sheet and and connect between sheet and leave the gap; Form an airtight balancing gate pit between said return diaphragm and housing, said housing bottom is provided with the pressure channel that communicates with this balancing gate pit, and said contact is provided with stainless steel substrates outside the contact.
Said make contact places the below of connection sheet and contacts with the connection sheet through stainless steel substrates.
The present invention is provided with stainless steel substrates outside the contact contact, can prevent to contact the contact effectively because of the oxidation and rusting that is heated, and has guaranteed the precision and the sensitivity of contact contact, the useful life that has strengthened pressure switch.
Advantage of the present invention is: be difficult for getting rusty, long service life, switch precision and sensitivity are strong.
