Editing Omron B3G-S series (section)

==Description==
B3G-S switches have both "OMRON" and "B3G-S" written on the top of the shell, allowing them to be easily recognised without needing to be de-soldered and removed from the keyboard.

The 1986 catalogue entry for B3G-S is subtitled  「DIN規格に適した全18.1mmのロープロタイプ」: the switch is noted as being DIN compliant.

The shells of some white-slider switches contained a slot for an LED; some keyboards used these switches without LEDs fitted.

There is a slightly smaller Omron keyswitch, provisionally termed the [[Omron Alps-style switch]] for its more Alps-like slider, that has the Omron branding on the bottom, and only two legs in the switchplate.

The switchplate in the B3G-S series is a partially sealed unit: the front panel affixes to the back panel using melted plastic lugs. The contact bridge fits so tightly into the back panel that it is virtually impossible to remove it. The centre leg is also fitted in such a way that it is impossible to remove it: the movable contact lug is above a square block of metal that is walled in on all four sides, with the leg protruding from a hole in the plastic. It is possible that the plastic is moulded in around the metal, as it does not appear possible to assemble the switch. No switchplate has ever been sighted fully disassembled. In comparison, the Alps switchplate is a simple sandwich of metal and plastic layers that can be manually disassembled and reassembled with very little damage.

The switchplate itself simply holds a very thin strip of a copper-coloured, ferrous alloy; the top of this strip is pressed against a static contact by the actuator leaf, by way of a plastic leaf on the switchplate front panel.
