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.

Soldering position
When wrapping or soldering a wire
around a terminal, do so in the shaded
area indicated in the diagram at left.
