Snap-in Pushbutton Switches
-
The 8W Snap-in Pushbutton switch is an 8R Soft Touch Pushbutton switch with a 12 mm square button and a
mounting frame. -
The panel cut-out dimensions are the same as the 8H series Lever & Rocker switcheswhich enables side-by-side mounting.
-
Buttons and mounting frames are available in 4 colors.
-
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.
