Outline： Detection switch, a kind of position switch (also known as travel arrangement switch, positioning switch), is a common electrical product of low current cam controller. The production and processing kinetic energy components shall be used to impact the isolator to complete the connection or disconnection of the control circuit to ensure a certain control purpose. In general, this switch is used to limit the position or schedule of molecular thermal exercise, so that the industrial equipment for sports and fitness can automatically stop, repeatedly exercise, speed change exercise or automatic back and forth sports and fitness according to a certain position or schedule.

[Detection switch] What should be paid attention to in the selection and installation of detection switch?

Detection switch, a kind of position switch (also known as travel arrangement switch, positioning switch), is a common electrical product of low current cam controller. The production and processing kinetic energy components shall be used to impact the isolator to complete the connection or disconnection of the control circuit to ensure a certain control purpose. In general, this switch is used to limit the position or schedule of molecular thermal exercise, so that the industrial equipment for sports and fitness can automatically stop, repeatedly exercise, speed change exercise or automatic back and forth sports and fitness according to a certain position or schedule.

1. The assembly position shall be accurate and the assembly shall be firm; The direction of barrel rolling shall not be disordered, and the impact position between the stopper and the stopper shall comply with the relevant provisions of the control line to ensure the reliable impact with the stopper.

2. Under the condition of operation, regular inspection and maintenance shall be carried out, oil stains and dust shall be removed, disconnectors shall be checked frequently for flexibility and reliability, and common faults shall be detected in time. Avoid mechanical equipment and safety production accidents caused by unscientific contact or loose connection of positioning switch.

3. It depends on where you use it. If you use a point with a relatively poor ecological environment, you must also pay attention to selecting a point with a relatively high IP rating. The positioning switch can be subdivided into travel arrangement switch and green axis switch by customers. Like the power industry, the demagnetizing magnetic blow type travel arrangement switch is generally used, which will bear very large DC current.

4. If it is used to detect the switch, connect the normally closed point of the detection switch to the control circuit. If it is used to connect other circuits, connect the time delay relay of the switch to the corresponding control circuit. In fact, the detection switch is only a general function key switch, with the same scope of application.

5.20V switch power safety fire line is connected to the common point of the detection switch, then to the normally closed point at the opening and closing points according to your scope of application, and to the A1 point of the DC contactor; A2 is connected to neutral line. Install the detection switch at the required location, adjust the touch interval, and then connect the normally closed point of the switch to the control circuit to complete the assembly.
