"Without pictures, it's just a story"

Both the Bite Switch and the Tongue Switch come with a durable 36 inch (90 cm) coaxial, round cross-section wire 1/8 inch (4mm) in diameter, making for a clean, streamlined design that cannot be pulled apart and does not clutter the helmet setup like some two-wire switches.

Both designs come with a 3/32 inch (2.5mm) 2-contact "mono" or 3-contact "stereo" right-angle plug that will fit the very popular Canon still cameras. Many users prefer the "mono" plug, which activates the camera's autofocus and light-metering functions whenever the camera is turned on and the switch plugged in. This results in a very quick shutter reaction time, however the constant autofocusing increases battery consumption.

Photographers who prefer autofocusing and metering with each individual exposure should choose their switch with a "stereo" plug. This does conserve battery power, but it also slows down reaction time somewhat depending on the auto-focusing and metering speed. Either type will work with our recommended camera configuration in which the camera is manually focused at the expected distance of the subject and the focus ring taped down. This will result in extremely fast shutter reaction time and will save battery life as well. With adequately fast film, a small aperture (preferably an F-number over 8), and good lighting, the photograph quality will be excellent.

Both the Tongue Switch and Bite Switch are manufactured with either a 2-contact "mono" plug or 3-contact "stereo" plug. These are 2.5mm plugs which fit the EOS Rebel series and many other Canon cameras. Most other makes of camera, such as Minolta, Nikon, and Olympus, use proprietary factory plugs which can be obtained only from the manufacturer or a camera shop, usually by cutting the plug off of a hand-operated switch. The standard plug 2.5mm plug can be easily removed by the user and replaced with a plug specific to the user's camera. Conceptus switches each come with detailed instructions for this connection procedure.

When used with Canon cameras in autofocus mode, the two standard plug types will yield different autofocus and metering characteristics. The mono plug will cause the camera to autofocus and meter constantly while the camera is on and the switch plugged in. This results in very rapid shutter reaction time at the expense of increased battery drain. This configuration works best when photographing freeflyers, freestylists, skysurfers, and other moving subjects. The stereo plug will cause the camera to autofocus and meter with each individual exposure. This increases battery life, but slows down the shutter reaction time. This configuration works best will large, relatively stationary formations.

When using a camera in manual focus mode, both plugs will yield the same quick reaction time as the mono plug with the battery conservation of the stereo plug. For this reason, we highly recommend using manual focus whenever possible. The camera should be focused at the expected distance of the subject and the focus ring securely taped in place.

With other camera types, the plug can be spliced to the switch to give similar operating functions. The bare copper ground leads are always connected to each other. Connecting the shutter and autofocus leads from the plug to the white (and red, if the switch came with a stereo plug) lead from the switch will give the same results as if using a stereo plug and the same results as most factory hand-switches. Connecting the shutter release lead to the white (or red) wire and the autofocus lead to the ground lead of the switch will give the same results as if using the mono plug. Either type will work with our recommendation of using manual focus.

With any of the above configurations, the camera should be turned off and the switch unplugged in order to conserve battery power and prevent unintentional photographs.
