A new interlock switch design incorporating use of a miniature snap-action switch for high level switching and a solid state switch (Hall effect or opt0 coupled) for example, for low level switching. The new switch is designed to have a longer actuation distance, lower actuator forces, 1-13. pounds maximum, and a reliability that meets or exceeds the high volume market needs. When the plunger is displaced by approximately 7mm the maximum force the actuator can see is 1.5pounds.
