Abstract
In a keyboard for presetting tuning in e.g. an automobile radio a pivoted bracket 27 is mechanically connected to a tuning system of the radio for programming a memory plunger 14 of each key 10. Horizontal sections 33 (33', Fig. 2) of the bracket 27 are arranged over opposite faces of a fixed support plate 1 so as to engage with plungers 14 of two series of keys 10 one above the other. When a key is pulled outwardly a resilient lock 13 releases a plunger 14 of that key and enables a tuning knob 6 to adjust bracket 27 to the required station. On pressing in the key the plunger engages a horizontal section 33 of the bracket and is locked by 13 in this position. When that key is subsequently pressed a slide 21 declutches the bracket 27 from the tuning knob 6, the memory plunger 14 positions the bracket to the required position and a slidable latch 2 retains the key.
