AS-F*M, AS-F*C, Speed Controller, One-touch, -Ld89

The AS-F*M and AS-F*C series of speed controls bring the convenience of the push lock and indicator functions to the low speed models.  Additionally, they now offer two low speed ranges, M (1~50 mm/s) and C (50~150 mm/s) to provide finer adjustment and greater accuracy of speed within the desired operating range.
