Omron clone

An Omron clone is a clone of an Omron B3G-S series switch. Per the 1986 B3G-S specification, the switch is 13.4 mm squared at the plate level (fitting a 13.5 mm squared hole), and 12.2 mm from top to bottom excluding the slider.

While the B3G-S design has inspired other switches, unlike with Alps clones these copies do not all follow the Omron physical specification.
