19mm Metal Switch- China Suppliers Factory Manufacturers

The core of industrial control is the control of the motor, the core of the motor control is the contactor, the conventional component of the contactor coil control is the button switch, today we will take the button switch of GQELE Electric as an example, briefly introduce the function of the button switch in the second Function, use and installation in control loops.

Installation category

This series of buttons are φ22mm panel mounting buttons, and the panel mounting holes are φ22.7mm~φ22.3mm. Standard buttons can use 1~6mm thick mounting panels, and economical buttons can use 1~4mm thick mounting panels.

Button (button) is a commonly used control electrical component. It is a switch used to control certain functions of machinery or programs, or to turn on and off control circuits, so as to achieve the purpose of controlling the operation of motors or other electrical equipment. Generally speaking, the red button is used to stop a certain function, while the green button is to start a certain function.

Waterproof push button switches, as the name suggests, are switches that can be operated with wet hands. In some humid environments, it can be used with confidence because it has good sealing performance. The highest IP rating of the waterproof switch is IP68. The waterproof button switch has a reasonable design, long service life, high temperature resistance, and current shock resistance, which can meet your specific use needs.

Precautions

The specific application of these waterproof switches is restricted by many factors, such as the installation method and the installation direction of the product, the pressure difference of the airflow acting on the product, the strength of the fluid rebound and the working voltage. We also need to prevent the intrusion of corrosive gases or the intrusion of substances.

The waterproof metal switch cooperates with the circuit breaker to perform switch operations according to the needs of the system operation mode, and change the system operation wiring mode.

A push button is a manually controlled master electrical appliance. It is mainly used to issue operation commands, turn on or off the control circuit, and control the operation of mechanical and electrical equipment. The working principle of the button is very simple. For the normally open contact, the circuit is disconnected before the button is pressed. After the button is pressed, the normally open contact is connected and the circuit is also connected; for the normally closed contact, Before the button is pressed, the contacts are closed, and when the button is pressed, the contacts are opened and the circuit is broken. Due to the needs of the work of the control circuit, a button can also have multiple pairs of contacts that act simultaneously.

Buttons have a wide range of uses, such as starting and stopping of lathes, forward rotation and reverse rotation, etc.; start, stop, rise, fall, forward, backward, left, right, slow or fast operation of tower cranes, etc., all need buttons control.

The push button switch refers to a switch that uses a button to push the transmission mechanism to make the moving contact and the static contact press on or off and realize the circuit switching. The push button switch is a kind of master electrical appliance with simple structure and wide application. In electrical automatic control circuits, it is used to manually send control signals to control contactors, relays, electromagnetic starters, etc.
