Description

alps.tw Type OD1 is an Alps mount switch. The internals are similar to those of the KPT switch, but it is not a clone. All known variants feature a copper click leaf with a wide base and a narrow upper half. The mechanism by which the switch is secured into the plate is similar to that of the KPT switch and Omron B3G-S series.

Variants

At least two variants of this switch have been discovered so far.

Three pin (Black slider)

This variant has three legs like an Omron B3G-S series or KPT switch. The base is either designed to be reversible, or to support DPST.

There are no known photos of the switch in situ, so it is unclear how many are unmarked and how many are marked "D-TRNS".

A very similar switch has been found in another Costar keyboard, this time branded "D-TRANS"; the internals have not been inspected.[1]

Two pin (White slider)

This variant has two legs arranged similarly to Alps and Alps clone switches. It is compatible with Alps plates and PCBs. The internal components appear identical to the three pin version, but the mounting clips on the switch housings are different.
