Jiffy-Drill

Electric Limit Switches:

The electric limit switches mounted inside the top cover of the Jiffy-Drill are of high quality with a life expectancy of 20,000,000 cycles. Each switch has a common, a normally open (N.O.), and a normally closed (N.C.) set of contacts, permitting them to be used in almost any electrical control circuit devised for the Jiffy-Drill. On standard basic Jiffy-Drill units these switches are unwired, and the external wiring brought through the conduit hole in the rear of the switch cover. Electrical Option EP is available. This is a 12-ft. cable wired to all terminals on the switches and to frame ground, and brought in through an 8-pin plug and socket in the switch cover. This permits the Jiffy-Drill to be unplugged quickly from its wiring.

The position of all limit switches may be adjusted to control Drilling depth, rapid feed position and retracted position of the spindle.
