Abstract
A reciprocal switch includes a shell with a stopper located therein, a connecting unit located on two sides of the stopper for generating circuit signals, two conducting units having movable contacts located on two sides of the stopper and engaged with an elastic element, and a displacement unit located between the two conducting units and exposed outside the shell. The displacement unit may be moved when subject to an external force to move the conducting units moving to either side to press the connecting unit on one side to generate circuit signals.
Claims8
A reciprocal switch for variable closed switching patterns, comprising:
- a shell having a slot formed on a top surface thereof, a stopper located therein, and a fixed contact connecting unit located respectively on two sides of the stopper for generating circuit signals;
- a displacement unit located in the shell having a strut mounted to a top surface thereof extending through the slot;
- and
- two sets of movable bridging contact conducting units located respectively on two sides of the displacement unit connected by an elastic element and having respectively a conductive flange for connecting contact legs of the connecting unit, and a pair of brake ledges on two sides thereof to contact two lateral sides of the stopper;
- wherein the strut is movable to either side of the switch when subjected to an external force and drives the displacement unit to move the conducting units such that the conductive flange of one conducting unit presses the connecting unit at one side to generate circuit signals and the brake ledge of another conducting unit is stopped by the stopper to allow the elastic element to stretch to generate a restoring force, and the displacement unit being returned to its original position when the external force is released.
