INTRODUCTION TO 4P CONNECTORS FOR THE AJ8 SWITCH 
(produced by Nippon Tanshi co.,Ltd)
1. Switch mounting
Mount the switch with the hole cutting 
dimensions shown in the dimensions.
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 
(60W 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 a 
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 perfomance.
Contact terminal and ground terminal
Soldering position
When wrapping or soldering a wire 
around a terminal, do so in the shaded 
area indicated in the diagram at left.
