Outline： Never use the detection switch alone when there is combustible or flammable mixture. Electric arc caused by switch heating may cause safety accidents

Which three points should be paid attention to when using the detection switch?

1. Electrical standards

The switching value of AC and DC power supply is very different. Please use the detection switch within the rated current range. The control ability of DC power supply site is relatively low.

This is actually because there is no zero point. Once the arc is caused, it cannot be dissipated, and the arc lasts for a long time. And the current direction is established, so

Contact migration will occur so that the contact cannot be broken due to unevenness.

2. Contact protection power circuit

In order to facilitate the service life of the detection switch circuit breaker, prevent noise and reduce carbon or sodium cyanide caused by arc, the circuit breaker is used to protect the switching power supply

Road. However, if the operation is wrong, it is very likely to be penny wise and pound foolish.

3. Application Scenario

Never use the detection switch alone when there is combustible or flammable mixture. Electric arc caused by switch heating may cause safety accidents

Or explosion accidents. The switch is not a waterproof and airtight structure, so a protective cover is used to prevent oil or water from flowing, fluttering or dust from adhering

Liquid immediately.

[Detection switch] What should be paid attention to when selecting the detection switch for installation?

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.
