Do I have to keep holding the on button for it to keep on working or does it have an on and off switch?

It is intentionally designed (for safety purposes) only to work when there is finger pressure on the power button. When you release pressure, it stops.

Your hand on the grip activates the switch. It doesn't take much pressure to turn it on. It turns off when you let go. The way it is designed to be used makes this switch mechanism logical.

no it does not. it will go on and stay on until power comes on or it runs out. if there is a power failure and it appears that it will last some time, i turn the device off. i also had the previous version of this and this feature (have an easy accessible switch) is great. maybe on the next version it can contact you although i am not sure what you will with that info.

It does have an on/off switch. Works well, just be careful not to put in too many pieces of paper at once. It can handle 12 pieces of paper, but on 12 of anything thick. It wil jam and you have to turn it off, and unplug to be safe, up end it and pick out the pieces with a tweezer. Just use 10 sheets or even 8. Also, buy the oiled paper and use after heavy usage to keep the blades from rusting.

Yes you have to hold the button to keep the light on. Haven't had to replace the batteries yet and I have used it routinely for months.

No, there is no on/off switch. When you plug it in after you've put the water in, it starts to work.

It does not have an on & off switch. It doesn't need one. It's very similar to a liquid crystal wristwatch or bicycle speedometer - it uses very little energy to keep it going. The button cell battery is replaceable, however. I have used this model for 9 years and find that the battery (for me) lasts well over a year - sometimes two. I actually have more trouble with the plastic bracket that clips to a belt or clothing. I usually end up breaking it while I'm on vacation if I am not careful sitting down in an airplane seat or tour bus seat. Consequently, I usually buy them two at a time on Amazon to get the free shipping.

It stays on, no need to hold the button down. It will turn off in spray mode and turn back on in spray mode if you dont switch it back.

No it has no switch for ON/OFF. Just plug in to turn on and unplug to turn off. Have have had one for 18 years before I got this one and never had a problem until I forgot to take it in and it froze.

No it does not have an on, off switch. It comes on when the computer is started and goes off when the computer is turned off.

Hello Barbara,This plugs in and does need to have the switch continually held. That said I'm fairly happy with it and as I'm unlikely to know ahead of time when I need it prefer to not worry about the battery being dead.

Depending on the one you buy. This one, "On/Off" version, means that it will click in when on and stay clicked in. In this manner it will "remember" that it is ON. You need to click it in again for it to go OFF. The other version is the one where you need to hold it in to have it stay on. Probably more suitable for an application for where you want to flash high beams or something like that. Hope this helps!

No it doesn't have an on/off switch. However, while it does take two AAA batteries, I bought my keyboard just over 3 months ago, use it for both work and my personal computing (including gaming), and the batteries just died on me for the first time last night. So it's very efficient with its power use.

No, and one of its more annoying aspects is that it doesn't have an on/off switch, so you more or less have to keep it on all the time or keep plugging and unplugging it.

It has a toggle switch. Manual, but not terrible. If it's plugged into something that you turn on and off, it'll run when that component is turned on.

yes it has on/off switch but switch is poor quality. I have had to replace the switch in my pump after about 10 uses.

You don't have to hold a button. Its a switch. Up for on and down for off (or it could be the other way around as I can't remember which direction) but the switch will stay locked in what ever direction you put it.

No 'on/off' switch. However, it's a powered cathode that can easily be unplugged!
