OP enclosed switches are precision snap-
action switches sealed in rugged cast alumi-
num housings. Cover and shaft seals keep
out moisture and other contaminants on ro-
tary operated switches. The plungers in the
Q-plunger version are not sealed.
Refer to page A123 for explosion-proof Type
EX switches, which are dimensionally inter-
changeable with OP switches.
