Abstract : The invention is directed to providing an improved dual threshold switch having an elongate, dielectric envelope containing a pair of reed contacts actuatable to an open position and a closed position by external magnetic actuation fields. Means are carried on the elongate dielectric envelope for magnetically inducing a 360 degrees magnetic biasing of the reed contacts to the open position and a closed position at two magnetic thresholds.
