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.
2-way light switches do not have a ground terminal because they do not need to be grounded for their basic function of controlling the flow of electricity. The switch operates by interrupting or completing the circuit to turn the light on or off, which does not require a ground connection. However, modern electrical codes often require grounding for safety reasons, so it is recommended to consult local regulations when installing switches.
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.

5 way intermediate lighting wiring diagram?
Install a double-pole switch at the entrance and end of a hallway to control lighting from both sides. Wire a 3-core cable between the switches and connect the live wires to the common terminals, while the switched live wires are connected to the L1 and L2 terminals on each switch. The lighting circuit is wired to the common terminal on both switches. Utilize a two-way lighting circuit when controlling a single light fitting from two different switches. Connect a 3-core cable between the switches, with the live wire connected to the common terminal on both switches. Link L1 to L1 and L2 to L2 on each switch, and connect the lighting circuit to the common terminal on both switches. Employ a two-way and intermediate lighting circuit for controlling a single light fitting from three different switches. Wire a 4-core cable between the switches and light fitting, connecting the live wire to the common terminal on each switch. Link L1 to L1 and L2 to L2 on the two-way switches, and connect the common terminal on the intermediate switch to the lighting circuit. For a 4-way lighting circuit controlling a single light fitting from four different switches, use a 5-core cable between the switches and light fitting. Connect the live wire to the common terminal on each switch, and link L1 to L1 and L2 to L2 on the two-way switches. The common terminal on the intermediate switches is connected to the lighting circuit. If wiring multiple lights in a large room or area, consider using a combination of two-way, intermediate, and/or four-way lighting circuits as necessary to control the lighting from various switch locations. Plan the wiring scheme carefully to ensure proper functionality and compliance with electrical regulations.
What is a 2way hookup at a campground?
water and electricity.
How do you split ceiling fan to be controlled by a 2way switch and the light by 2-3ways?
By 2 way switch I assume you mean a single pole switch. If so yes this can be done.
In which professions would it be beneficial to have 2way radios?
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.

Home that has a 2way electrical switch 110 v-how does it operate?
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.
What speakers have better sound 2way or 3way?
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.

What are the functions of a 2way radio?
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.

What is the meaning behind saying 10 4 when you have understood something on a Bus or truck 2way 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.
