The control button switch is the intermediate link between the operator and the control device. It can be seen that the correct installation of the control button switch is very important. Hongbao Electric has compiled a small section to introduce in detail the installation position and wiring process of the control button switch.
When installing the control button, first measure the diameter of the button thread, drill the installation hole on the control panel, exit the button nut, thread the button threaded column through the back of the control panel, adjust the stop on the threaded column to the appropriate position, and then screw the button on the threaded column from the front of the control panel and tighten it.
When the buttons are installed on the panel, they should be arranged orderly and arranged reasonably. It can be arranged from top to bottom or from left to right according to the order of motor starting.
Several different working states of moving parts of the same equipment, including up and down, front and back, left and right, tightness, etc., need to install each pair of buttons in the opposite state together.
In order to deal with emergencies, when there are more buttons installed on the button board, the red mushroom head button is used as the main stop button, and it is installed in a conspicuous and easy to operate place.
In general, a button always has a pair of moving contact and a pair of moving and breaking contacts. Before connecting, use the multimeter resistance to distinguish the corresponding contact.
The exception is that some of them have two pairs of contacts with indicator light, which should be paid more attention to when wiring.
The button board and box for installing buttons must be metal, and try to connect them with the general grounding bus of the equipment. For hanging buttons, special grounding wire must be set, and metal tube is not allowed to be used as ground wire.
