Multi-contact pressure connection switch

The invention discloses a multi-contact pressure connection switch. An upper board (1) and a lower board (2) are in the same long-strip shape and are formed by PCB (Printed Circuit Board)s; the board surfaces of the upper board (1) and the lower board (2) are parallel, and the side edges of the upper board (1) and the lower board (2) are aligned; the lower surface of the upper board (1) is provided with multiple series-connection contacts in equal distances along a long-edge direction, and the upper surface of the lower board (2) is correspondingly provided with multiple series-connection contacts of which the number is the same as that of the contacts on the upper board (1); tin-soldering plates (3) which are formed by soldered tin and are bulged on the board surfaces are arranged on all contacts; more than one spring (4) is also arranged between the upper board (1) and the lower board; the upper board (1) and the lower board (2) are respectively provided with lead-out wires (5 and 6) which are respectively communicated with the contacts of the upper board (1) and the lower board (2); the left end part of the upper board (1) is movably sleeved at the upper part of a left guide rod (7), and the left end part of the lower board (2) is fixedly arranged at the lower part of the left guide rod (7); and the right end part of the upper board (1) is movably sleeved at the upper part of a right guide rod (8), and the right end part of the lower board (2) is fixedly arranged at the lower part of the right guide rod (8).
