A red push button is easy to notice, but its colour does not tell you what happens inside the switch. It may provide a momentary command, hold a contact in a changed state or combine switching with illumination. Choosing the right device starts with the required control function, not the colour of its head. For […]

A round push button switch gives an operator a clear, physical way to issue a command. On a machine panel, that command might start a cycle, reset an alarm or request a change of operating mode. The circular head is easy to arrange in a panel, but its shape tells you little about the electrical […]

What is an AC relay switch? AC relay switch is an electrical component used to control AC circuits. It uses electromagnetic principles to achieve on-off control of the circuit. When a control signal (usually a low voltage or low current signal) is applied to the input end, the electromagnetic coil inside the relay generates a magnetic field, […]

What is a Door Limit Switch Door Limit Switch, also known as door limit switch, is an electrical switch device used to detect the door position. When the door opens or closes to a predetermined position, the limit switch triggers the circuit action, thereby realizing the monitoring and control of the door status. It is usually […]

What is an Electrical Limit Switch An Electrical Limit Switch is a switch device used to detect mechanical position or travel. When an object (such as a robotic arm or moving part) reaches a preset position, the limit switch is triggered and the circuit state is switched. It converts electrical signals by opening and closing […]

The purpose of limit switch connection The purpose of limit switch connection is to control the movement or operation in mechanical equipment or systems, and to achieve automatic control and protection functions by detecting the preset position or state. Limit switches can help equipment automatically stop or switch operations when reaching a specified position, preventing […]
