Abstract:
A multiple load sequence controller for alternating loads for each successive sequence cycle, comprising:sensor means for sensing a condition requiring a load to be activated;a first relay connected to receive power from said sensor means, said first relay including a double throw contact set having a first normally closed contact and a first normally open contact, wherein energizing said first relay causes said double throw contact set to change states;a second relay connected to receive power through a first switch via said first normally closed contact of said double throw contact set, wherein when said second relay is energized a first load is actuated and said first coil is energized causing said double throw contact set to change states; anda third relay connected to receive power through a second switch via said first normally open contact of said double throw contact set, wherein when said third relay is energized on a successive cycle a second load is actuated,wherein when either said first switch or said second switch is placed in an off position said first relay causes power to flow to the other of said first or said second switch.
