Problems solved by technology
When used in high temperature, humidity, dust, irregular vibration of moving machinery, etc., it is easy to have single or difficult failures such as lever deformation, aging of rollers and return springs, weakening or failure of elastic force, poor contact between moving contacts and static contacts or difficulty in breaking. Various forms of malfunction
Affected by environmental factors, it is difficult for maintenance personnel to repair or replace it, which seriously restricts the automation of PLC for the control of motion machinery.

Embodiment Construction
[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0014] see figure 1 with figure 2 , a touch switch equivalent to a travel switch, including an insulating material 2, on which a touch spring 1 connected to the intermediate relay coil through a wire and a "ground" reliably connected through a wire are fixed on the insulating material 2 The secondary grounding spring 4 is vertically above the secondary grounding spring 4 and is provided with a striker 5 on the moving machine. When the striker 5 on the moving machine moves vertically downward and touches the secondary grounding spring 4, The striker 5 first touches the secondary grounding spring 4 after being reliably connected to the "ground" and then touches the touch spring 1. The touch spring 1 is connected to the "ground", and at this time the intermediate relay coil is connected to the "ground". Thus forming a control loop.

The invention relates to a touch switch equivalently applied as a stroke switch and an application of the touch switch. The touch switch comprises an insulating material. The insulating material is fixedly provided with a touch spring connected with an intermediate relay coil through a wire and a secondary earthing spring reliably earthed through a wire. Bumping iron arranged on motion machinery is vertically arranged above the secondary earthing spring. When the bumping iron on the motion machinery moves vertically and downwards and makes contact with the secondary earthing spring, the bumping ion makes contact with the secondary earthing spring firstly, is earthed reliably and then makes contact with the touch spring. The touch spring is earthed. Then the intermediate relay coil is earthed, and a control loop of the touch switch is formed. According to the touch switch, the stroke switch in a PLC control system is omitted, and the purchasing cost and maintenance cost of spare parts are reduced; in the production control process, the failures of fuse burning caused by power short circuit, earthing and the like in the control loop can be avoided effectively, and the failure rate of the control system is reduced.
Description
technical field [0001] The invention belongs to the technical field of stroke switches of PLC control systems, and relates to a touch switch equivalent to a stroke switch for automatic control of mechanical equipment by sending instructions to the PLC control system after touching iron and springs and its application . Background technique [0002] Travel switches are widely used in PLC control systems. The known roller travel switches are composed of rollers, levers, return springs, normally open and normally closed contacts, and a shell. When used in high temperature, humidity, dust, irregular vibration of moving machinery, etc., it is easy to have single or difficult failures such as lever deformation, aging of rollers and return springs, weakening or failure of elastic force, poor contact between moving contacts and static contacts or difficulty in breaking. Various forms of failure phenomena. Affected by environmental factors, it is difficult for maintenance personnel...
