Abstract

Dust seal bag 10 encloses microswitch 11 with conductors 12 extending through the open end. A tie or heat shrinkable plastic loop 15 closes the open end of bag 10 about conductors 12. Lever 13 pivots about pin 14 to operate the switch actuator 16 through the bag 10 wall. The switch can be installed by mounting with screws 18 which pierce the bag and secure the assembly compressively to the associated support member. Bags of polyurethane material are effective to prevent switch failure in dust laden atmospheres. The bags afford excellent mechanical wear properties and are pliable to preclude the imposition of any appreciable increase in the required actuator force.
