The North American 1447 can be ordered with two-position indi- cation switches only. Single position is not available. Specify -LL after the part number. Example: 1447-2-LL. The position indicator consists of two micro-switches with roller arms. Each switch is mounted on a carrier. Separate threaded spindles enables them to be independently adjusted for a max- imum stroke of 20 mm. The unit is mounted on a plastic base that can be rotated 360 degrees. The complete assembly fits under a transparent hood which fits on the base plate. Two PG 9 cable glands are supplied for the electrical connections. Integral LED indicators show whether the circuit is open (red LED) and that the system voltage is present (green LED). (See Figure 1 for electrical wiring diagram.)
