AJ8 (J8) Switches

AJ8 (J8) Switches Causions For Use

1.Switch mounting

Mount the switch with the hole cutting dimensions shown in the dimensions.
Please contact us if you are considering using a panel of other than the recommended size and shape.

2.Regarding fastening lead wires to terminals

  • 1.When connecting the tab terminals, use a .250 Quick-connect and insert the terminals straight in.
    If they are skewed, the terminals will require excessive insertion force.
    In addition, there is some variation in the insertion force required for different receptacles from different manufacturers, so confirm how much force is needed under actual conditions.
    Do not solder wires onto tab terminals.
  • 2.With manual soldering: Complete the soldering connection work within 3 seconds with the tip of the soldering iron at a temperature of 420°C or lower, and take care not to apply any force to the terminal area.
    Avoid touching the switch with soldering iron.

Refer to the diagram above, "soldering position," for details on the position where a wire should be soldered to a terminal.
When soldering PC board terminals, keep soldering time to within 5 s at 270°C soldering bath or within 3 s at 350°C soldering bath.

  • 3.The terminals should be connected in such a way that they are not under constant stress from the connecting wires.
  • 4.Terminal material is copper alloy which may discolor due to finger's oil or after long time. But that discoloration does not effect actual performance.

3.Resistance to chemicals

To clean the switch unit, use a neutral detergent diluted with water.
Do not use acidic or alkaline solvents as they may damage the switch.
Furthermore, be careful not to get any of the detergent solution inside of the switch while cleaning it.

4.Environment

Avoid using and storing these switches in a location where they will be exposed to corrosive gases, silicon, or high dust levels, all of which can have an adverse effect on the contacts.

5.Take care not to drop the product as it may impair performance.
