Today I will focus on the instructions related to the 30mm la38 button switch. Many customers have purchased our 30mm button with mounting holes but do not know how to use or install it? The 30mm pushbutton switch is different from the 22mm mounting hole button except for the installation hole and components, and the other functions, styles, and colors are the same. The ka series pushbutton switch is made of environmentally friendly plastic heads, and the price is lower than that of metal. Customers who want an economical version can buy buttons made of this plastic material. The Kb series is made of metal brass chrome-plated material heads, and the contacts at the bottom are all universal. If you buy the ka series buttons, you can also replace them with the kb series button heads if you want to buy them later. The biggest difference between Kb and ks is the difference in the mounting holes. Kb is for 22mm mounting holes and ks is for 30mm mounting holes.
When you receive our ks series push button switch, you will find that when the black thread is removed, there will be a transparent component that will also fall off, this is because it is used to fix the button on the panel when the button is installed in the panel A device behind. Only when the transparent component is removed and placed behind the panel can it be installed on a 30mm panel, otherwise you will find that it can only be installed on a 22mm panel.
The correct installation method is as follows:
Step 1: Remove the outer packaging of the received button and take out the button
Step 2: Pull and twist the yellow safety catch to remove the head
Step 3: Take off the black fixing thread on the head, and take off the transparent ring at the same time.
Step 4: Place the head on the 30mm mounting panel, put the transparent ring behind the panel, and fix the black thread, so that the head is installed on the panel.
Step 5: Locate the “Top” logo near the head of the button and the base of the safety lock, align the positions, and rotate the yellow safety lock. The 30mm metal button can be successfully installed on the panel.
