Sliding contact current collector for servo potentiometer - has actuator sliding in lateral openings in base, to join or separate thin wire sliders in dependence on position

摘要

The device has a number of sliders (64,65) mfd. of e.g. thin Ag alloy wire spot-welded to the free ends of conductive strips (60,61) of e.g. thin Cu bronze. Two identical cubical sliding elements (42,43) have broadened sections (53,54) at the points of contact with respective tracks (40,41), and contact rivets (57,58) protruding from recesses (56) on the sides facing an upstanding contact (27) near the middle of the actuator (25) which brings together or separates the sliders according to the position of the device. USE/ADVANTAGE - For telecontrol applications i.e. for opening or closing valves via remote control signal. Operational safety is increased with either an indication given of a fault, or the entire appts. switched off.
