The only type of light switches that we know are the ones we see and buy in hardware dealers. These types of switches are known as a single-pole switch, which turns the light on and off with a single flipping of the lever up or down. However, if you are one of those who have homes with hallways or stairs that need a series of lights and needs to be controlled from multiple locations particularly from both ends of the hallway of staircase, then you probably need to have the three-way switches. Three-way switch has three terminal screws including the green grounding screw and got no “on” or “off” mark.

Keeping your lawn free from weed is easy and can be done in simple steps, which include removing of existing weeds, dethatching the lawn, aerating, applying grass seed to bare spots, mowing the grass, and watering and feeding the grass.

Removing your lawn’s existing weed can be done by pulling it off by hand or by a hand-held weeding tool and if the weeds are uncontrollable, use an herbicide and you are done. Next step is to dethatch the lawn to make way for weeds to grow using a rake, and then aerate your lawn, apply grass seeds to bare spot using a broadcast seed spreader, mow the grass properly when they are already establish then water and feed the grass.
