ABSTRACT:
A refuse compactor includes a frame enclosing a compaction ram for compacting waste deposited into a container. A safety chute, having a magnet, is detachably mounted to the frame via pivots and notches. A magnet sensing switch wired into the compactor's control circuit interacts with the magnet on the safety chute to prevent operation of the refuse compactor when the safety chute is misaligned or absent. A ring bolt, collar, spring and washer are mounted within the frame. A plunger on a contact switch wired into the compactor's control circuit touches the washer. The contact switch interacts with the washer on the ring bolt to prevent operation of the refuse compactor when a predetermined amount of weight is placed on the safety chute. Deflection of the spring moves the washer toward the spring, breaking contact between the washer and plunger, opening the contact switch and immediately disabling the compactor.
