Pushbutton switch 8R-N｜NIDEC COMPONENTS

Pushbutton switch 8R-N

FeaturesFeatures

The 8R Soft-Touch Pushbutton switches has a unique snap action structure which provides light and soft tactile feel.
The short travel distance (Alternate action: 2.5 mm,Momentary: 1 mm) and the low-profile design make the 8R series suitable for applications where panel space is limited
Silver or gold-plated contacts
Epoxy resin case: UL94V-0 self-extinguishing epoxy.
Insulation between terminal and ground: 4 mm minimum.
Prevention of flux entry: The epoxy resin seal on bottom of the switch helps prevent short-circuiting between poles ensuring high reliability
Insulation barrier: Insulation barrier design between poles helps prevent short-circuiting between poles ensuring high reliability.

Manual soldering
Device：Solder iron
①420 ℃ Max. 3 sec. Max.
Auto 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.
When 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.,

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.

Solvent : Fluorine or Alcohol type.
8A/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.
