Abstract

1528668 Touch-responsive switching circuit MASTER SPECIALITIES CO 16 June 1976 [18 July 1975] 24949/76 Heading G1N [Also in Division G4] A digital indicating switch comprises in combination a switch housing 11 having a face 12 with a seven-segment digital indicator 26 with segments 19-25 and with conductive touch-responsive areas 27, 28 on the face. A capacitive, resistive or heat-sensitive touch-responsive switch 33 has an input connected to an external clock generator 34 and a second input connected to one or both areas 27, 28 and provides a train of output pulses synchronized with the clock generator whilst an area is touched. The switch 33 includes a spark gap 55 protecting transistor 46 from damage due to static charge on the operator. A monostable multi-vibrator 35 is triggered on each pulse and provides a corresponding pulse to a counter 36. Thus application of a finger for a time equal to or less than the cycle time of the multi-vibrator produces only a single increment of the counter output. The counter output passes to an optional latch circuit 39 and thence to a BCD-seven-segment decoder 41 driving the indicator 26. The first touch area and its touch switch may advance the counter and the second area and touch-switch may decrement the counter or clear it, Fig. 4 (not shown). Or the switches may have separate multivibrators connected respectively to an up-count and down-count input of the counter Fig. 5 (not shown).
