AUXILIARY SIGNAL SWITCHES 8700 SERIES

All Maxon proof-of-open and proof-of-closure signal 

switches work in a similar manner; but due to different 

styles and types of top assembly housings, the switches 

appear in slightly different positions in the various types 

of valves. Illustrated at right are representative top 

housings for .375" – .75" Series 8700 (Fig. 1) valves. 

Switch locations are noted on sketch.
