Please use within the rated load scale. If used beyond the rated load scale, it will not only affect the durability of metal button switches, but may also cause dangerous situations such as heating and burning. Therefore, metal button switches, including instantaneous voltage and current, should be used within the range of rated voltage and rated current.

A button switch is a control switch that operates by applying force to a certain part of the human body (usually fingers or palms) and has spring energy storage reset. It is the most commonly used master electrical appliance. The current allowed to pass through the contact of the button is relatively small, generally not exceeding 5A. Therefore, in general, it does not directly control the on/off of the main circuit (high current circuit), but rather sends command signals in the control circuit (low current circuit) to control electrical appliances such as contactors and relays, and then they control the on/off, function conversion, or electrical interlocking of the main circuit.

In daily life, we often see many signal indicator lights, such as traffic lights. What are the reasons for signal indicator light malfunction? The signal indicator light manufacturer will take you to understand.

Firstly, the underground pipeline of the signal light is blocked and the signal light wires are out of service, resulting in aging and short circuit faults.

Second, during the Roadworks, the wire of the signal indicator light was accidentally damaged.

Thirdly, there are many departments responsible for the construction and maintenance of signal lights, with different construction requirements and construction standards, which makes it difficult and time-consuming to repair some signal light faults.

Fourthly, power outage and continuous rainy weather during power grid maintenance and renovation can cause signal light failures, so these reasons can all lead to damage to the signal indicator light. Therefore, it is necessary to pay more attention in practical life.
