Question: Is the switch only on the right hand side or on both?
Document: The Belkin Conserve Switch does what it says it does and is simple to use. It works well on counter-top height outlets. That being said, it's a right-handed switch and depending on where your outlet is relatively to various other things, having the option to have the switch on the left-hand side would be nice. Also, the light on the switch is a very light green and is hard to see if the room is lighted well.
Not great but they are what they say they are. Switch on right side is a bit of a pain. But it does work and we use them to turn some of our gadgets off like the Bunn Coffee machine that does not have an off switch.
It has form and function. The lime green highlights around the plug holes give it that fancy/techy look - not a cheapy dollar store quality to it. The right side has a recessed toggle switch that is off when off and light up green so you know it is on. Ever since I put these in, no more pulling and plugging just hit the switch and viola! I love it! Sometimes it's the simple things in life huh?
Works for external drives with no on / off switch - have bought many of these - just make sure you get the right power strip to maximize the number of these you can you at once
These work great. Like the switch on the side instead of the top & also the green light when they are turned on.Would recommend.
Great tool for saving money and your plugs as you will not need pull plugs. Switch has a green light on the side so it does tell you if it is on or off.
I have one connected to my PS3 that does not have a power off switch, one connected to my incline bike that has a delay before it turns off, and the last one connected to a little used TV that goes into standby when powered off. While none of these are a major source of electrical usage, these are a good solution to kill the power to a device when a power strip isn't the right solution.
These power conserve switches work well to do away with some of the pesky LEDs that stare at you on TV.s and the like. They really don't save alot in electricity though. By the was if you have a large, flat screen that plugs in in such a way that you could get to the switch easily (that's the key) it would then save you right at $1.00 per month and therefore pay for itself in 7 months.
Fortunately, the switches I kept appear to be working as advertised. I do think Belkin should adjust the design so they can be plugged in &#34;upside down&#34; - I have an outlet that has the plugs on the left and a switch on the right. Luckily the switch is not used, so I have these things covering it up. I'm hoping that having a switch on that doesn't have anything plugged into it isn't somehow negating the power saved with these things.
The switch on the side is so much more convienent  (can't spell) than the ones on ends, cause I was told the plugs can be put in either way, & I think mine are upside down.
Answer: Yeah, I emailed them telling them thy need to mKe both. But right now it only on the right side.
