Pushbutton switch 8R-N
- ●To buy this product, please go to the following Online Web stores.
Soft Touch Pushbutton Switches
- 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.

Soldering Specifications
- 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.,
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.
Flux Cleaning
- 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.
