BTC 53 series is a series of keyboards from BTC with BTC foam and foil switches. This term (styled as "B T C - 5 3 series") is included on the label of some 53-series keyboards.

53 series encompasses significant variation. There are several case styles, and the sliders can either be supported by a moulded plastic plate (as with BTC dome with slider keyboards), or in plate-mounted inserts as with Realforce keyboards. Both the linear (sub-keycap coil spring) and tactile (with a buckling rubber sleeve). All variants have BTC's 1.25-unit escape key.

The plastic plate under the keycaps has been found in both beige and black, and the sliders can be found in various colours, including white, cyan, yellow and pink.

There is a "MACRO" key in the lower left-hand corner of many 53 series keyboards, of unknown function.
