The poor contact of the travel switch can be solved by adjusting the switch position, cleaning the contact, tightening the connection line, and replacing the spring or contact. The following are the specific operation steps:
If the location of the travel switch is not accurate, it may result in poor contact. Check the installation position of the travel switch to ensure that it is in the correct collision position with the moving parts. If the position is not accurate, adjust the position of the switch so that it can properly contact the moving parts.
Dirt or oxide layers on the contact may result in poor contact. Turn off the power, remove the travel switch, and gently clean the contact surface with detergent or fine sandpaper. Make sure to remove all dirt and oxidation layers, then reinstall the travel switch.
If the connection line of the contact is loose or falls off, it will also lead to poor contact. Check the fastening of the cable. If it is loose, tighten the cable again. If the cable has fallen off, you need to reconnect or replace it with a new cable.
Poor contact may also result if the spring elasticity of the travel switch is weakened or the contact is damaged. In this case, a new spring or contact needs to be replaced. Select the spring or contact that matches the original travel switch and replace it according to the manufacturer's guidelines, if the connection wire of the contact is loose or falls off, it will also result in poor contact. Check the fastening of the cable. If it is loose, tighten the cable again. If the cable has fallen off, you need to reconnect or replace it with a new cable.
