An electrical switch construction and method of making the same are provided, the construction comprising a housing, a pair of electrical switching units carried by the housing, and a condition responsive actuator carried by the housing and being operatively associated with the units to serially operate the units as the sensed condition respectively reaches two different predetermined conditions. The actuator comprises an axially movable plunger for operating one of the units and a snap disc for operating the other of the units when snapped overcenter, the actuator having a spring operatively associated with the plunger and the snap disc to move the snap disc overcenter when the plunger is moved to a certain axial position thereof by the actuator sensing one of the conditions. The actuator has a tubular member telescopically disposed on the plunger and operatively interconnecting the snap disc to the other unit when the snap disc is snapped overcenter.
