Abstract

282,952. Stephenson, J. Nov. 22, 19-26. Keyboard switches; secret contact -combination switches, particularly intended for use with the igniting circuit of a motor vehicle, comprise a set of spring keys A-K, some of which when depressed close corresponding contacts connected in series, whilst at least one key, for example J, opens a contact J<1> normally closed and also connected in the same series. Each key is formed with a boss 19 adapted to coact with a spring locking plate 23 which holds the key when depressed, but subsequent depression of any other key releases the plate. The top of each key is formed with an internal spring 17, which returns the top to the same level whether the key is depressed or not. A separate releasing kev M is provided.
