RoHS Compliant
■Features
The 8P series is a panel seal pushbutton switch with
an O-ring to provide drip-proof and dust proof effect
(corresponding to IP67 rating). Since a locking ring cannot
be used because the panel seal is required, “D-cutting” is
provided to the sleeve to prevent the switch from rotating.
Note that the switch can also be mounted to a 6.5 mm dia.

■Precautions （8N・8P・8R・8W・8Y）
⑴Manual soldering
Device：Solder iron
①420℃ Max. 3 sec. Max.
⑵Auto soldering
②The above-stated soldering conditions shall apply
only to switches with straight terminals. Auto
soldering is not possible with right-angle terminals.
Switches with right-angle terminals should be
soldered manually according to the conditions
specified in (1) above.
⑶When putting the switches through an aging process
after they were soldered onto the printing board or after
installed into a complete end product, be sure to remove
the buttons ofthe switches.,
2. Mounting
●Do not bend the terminals before mounting the
switch on the PC board.
●After mounting the switch, do not place the device
in such a way that the device weight will be applied
on to the actuator of the switch.
●For switches with straight terminals, solder the
switch on the PC board after fixing the switch on
the panel with a nut.
3. Flux Cleaning
⑴Solvent : Fluorine or Alcohol type.
⑵8A/B/C/D/E/F/J/S series are not washable. To wash the
PC board, clean the soldering surface of the PC board
with a brush so that the switch is not exposed to the
cleaning solution.
