Is there an on/off switch or do they have to be placed on the fingers to depress some button that has to be continuously depressed for them to work?

There is an on/off switch - a small button which is obvious when you have one in your hand that slides toward/away from the LED bulb, as opposed to being pushed like a click-pen.

Yes there is an on/off switch on the top of them. They don't have to be on your finger to work and they light up very bight.

There is a nice positive sliding switch. Will stay on or off on its own. A small wide rubber band is on the light to fasten to your finger. I love mine.

No, they DO have on/off switches. Toggling the switch does not stop the buzzing. After a whole lot of playing around, I found that all I had to do was put in a fresh battery. My first battery lasted 6 months after the date of purchase. Lets see how long this second battery, a fresh one, lasts.

One of the on buttons turns them on and they stay on. The other on button turns them on - and then turns them off 4-6 hours later. It would help if the words on the bottom (on, off, on) were in a different color so you could read them easier!

Not really. The button works two ways - you can "pulse" it with a quick press, or press a little deeper and it'll lock in the "on" position.

These are momentary push buttons. The connection is only active while you are holding down the button.

No pressure switch. Tail switch flashlight, very sensitive though. Momentary on with light press, full press will click and stay on, 2 quick presses a nd will go to strobe mode til deactivated with another press. Easy to operate for me, but I've never like the pressure pad switches.

No. It's a cluster laser with an on off feature or momentary on with pressure switch. Excellent product!!.

Yes just twist them and pull a little to break the contact with the arrow. They will turn off. Just watch them as you handle them sometimes they will light up again.

There is a thumb valve that controls flow to the hand held and outer rings. If you have flow to the hand held, there is also the push button that has a shut off setting. Hope this helps

Yes, you press a button and they come off. Very good chair. My dad loves it.

Don't fully depress the button. Pushing it lightly will cycle between the intensities. Fully depress to turn on and off.

The off on button is in the slide release that comes with the laser. Push side to Side.

The button is an on/off switch. If you turn it off, no steam. Nice, if you had to stop in the middle of the job to tend to something else.

The switch is a 'slide to' on and 'slide to' off type switch - normally the switch would be moved to the on position - the light would be illuminated and stay that way until the user slid the switch to the off position - With mine, it is possible to partially slide the switch from off towards the on position and make a momentary contact which can be held and keep the light illuminated until released - I don't that the unit was designed this way and the 'momentary on while pressed' may not work for all microscopes - Here is a link to customer image that clearly shows the slide on/off switch -

It just makes a 'click' when you switch. If "A" is down and "B" is up, then when you depress "B", the "A" button makes a click when it pops up. It isn't noisy really.
