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.
A rotor on which a moving contact is attached is received and rotatably held in a body, and a knob is received and held in the body side by side with the rotor and is movable. A plurality of first and second teeth are circumferentially staggered with each other on an outer perimeter surface of the rotor near one end and near the other end, respectively, in the direction of the axis of the rotor to project from the surface. An inclined surface is formed in each of the first and second teeth. A projecting part is formed on the knob to project toward the rotor. In response to a depression of the knob, the projecting part pushes the inclined surface of the second teeth to rotate the rotor and, in response to a return of the knob, pushes the inclined surface of the first teeth to rotate the rotor.
The invention provides a push-button switch including: a star wheel which is rotated by a constant angular step in one direction by a depression of a push button that automatically returns; an indenter which is pressed against the outer periphery of the star wheel by a spring; a contact which is attached so as to corotate with the star wheel, and which serves as a movable contact; and terminals with which the contact is contacted in accordance with a rotation angle, and which serve as stationary contacts. A small projection having a rounded tip end is disposed in each of ridge portions of the star wheel. Even when the slope of each ridge portion does not have a large inclination angle, the star wheel is prevented from being stopped at a position where the ridge portion is opposed to the indenter.
Waterproof push button switches, as the name suggests, are switches that can be operated with wet hands. In some humid environments, Waterproof switch from Gaoqiao manufacturer 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.
