A change-over switch comprises pairs of resilient metal lamellµ 1<SP>1</SP> stiffened by rigid lamellµ 1<SP>11</SP> and carrying contacts 5 co-operating with contacts on resilient metal lamellae 1, the lamellµ 1, 1<SP>1</SP>, 1<SP>11</SP> being mounted in slits in fixed insulating plates 2, 3 and secured thereto by welds 6 on conducting areas 7. The lamellae 1 are also secured to a movable insulating plate 4 for simultaneous operation and the plates 2, 3 have spacers (not shown) terminals 13 connecting with the conducting areas 7 on plate 3. The lamellµ may be arranged in several lines with a single movable plate, Fig. 6 (not shown), or with a number of movable plates, Fig. 7 (not shown), which may be separately or conjointly controlled. One or other of the fixed insulating plates may be integral with a printed circuit, Figs. 4 and 5 (not shown). |
