The circuit is grounded within the recepticle box. There is no need to ground the actual switch. == ==
This is normally seen in older switch boxes with older devices. new devices are required to have a separate ground just for the device. Grounding a device through a receptacle box no longer meets code. The new code state that both the box and device must be separately grounded. I would recommend replacing the switch with a new one that has a grounding screw. The reasoning for this is twofold. First, grounding through a box to a device is notoriously unreliable and secondly when the device is pulled out of the box by a service person the device loses its ground thus causing a safety issue.
The type of switch (2-way, 3-way, 4-way) has nothing to do with whether the exposed metal parts would be grounded via a grounding terminal or by a compression clip under one or more screw-fastening devices on the strap, or no grounding at all. Only those with a separate grounding terminal are approved for new installation in countries using the NFPA National Electrical Code.
Older homes may have been wired before grounded cables were widely available, let alone required, in the 1950s (in the USA), so switches were not manufactured with any provision for a grounding wire that nobody had or thought they needed.
There are also homes in which the grounding wire was ADDED to the existing cloth-covered cable, or that were wired with continuous conduit or armor-clad methods.

By 2 way switch I assume you mean a single pole switch. If so yes this can be done.
There are a number of professions in which it would be beneficial to have 2way radios. Professions such as police, ambulance and fire need them to relay information quickly. Also security workers would benefit from them.
2way = invoice qnty = po qnty
hi, very good question got same problem but have now figured that one out simply by 1 2way sw then 3 intermediates then end with 1 2way. bright sparks.
This will probably make more sense if you draw it out. A light has two wires running to it. The switch breaks one of the lines. Draw two lines on a sheet of paper about 2 inches long. Draw a small circle in the middle to represent a light. Extend one of the lines to the light. To the side extend the other line to a box that represents the first switch. From that switch draw two lines to the second switch. Draw one line from the second switch back to the light. That completes the circuit. Power comes into the first switch on the single line and then through one of the two lines between the two switches and out the final single line to the light. It can use either of the two center lines depending on which way the switches are flipped. This makes sense to me, but it may be Greek to you. If you follow the drawing I think it should make sense.
This is a mostly a matter of personal opinion but I find the 2 way speakers to be less "harsh" with less screeching treble. Brand name can make a big difference as well, I personally prefer JVC 2way speakers as they have excellent vocal reproduction and a very reasonable price.
Just walkie-talkie or 2 way radio
"10-4" is a ten code used in two-way radio communication to signal understanding or acknowledgment. It comes from the ten code system used by law enforcement and emergency services to efficiently communicate over radio channels. Saying "10-4" indicates that the message has been received and understood.
Infinity Kappa is a car speaker that comes in a range of models which are to work out if it will fit ones car. An example on Amazon is an Infinity Kappa 6929i 2Way for just under $97.
A two way radio allows two persons to communicate with each other while separated by some sort of distance. A wireless frequency is used for them to communicate and they must be on the same channel.
