The amount of virtual terminals available is dependent on the switch itself. However, the average number is 15.
To wire a switch to a relay, first connect one terminal of the switch to the positive power source. Then, connect the other terminal of the switch to the relay's coil terminal. Next, connect the other coil terminal of the relay to the ground. This setup allows the switch to control the relay, activating it when the switch is closed.

One. A typical "two way" ON-OFF light switch is a Single Pole Single Throw (SPST) switch with two terminals. It is wired in series with the fixture: that is, the power circuit is routed from the breaker to one side of the switch. The other side of the switch is connected to the "phase" or "power" terminal of the fixture. In a 115VAC single phase circuit, the other terminal of the fixture is connected to neutral. A "three way" switch circuit consists of two switches in different locations, each of which is a Single Pole Double Throw (SPDT) switch with three terminals. A typical use would have one switch at the top and the other at the bottom of a set of stairs. For the sake of clarity, we can label the "common" terminal on a SPDT switch the "C" terminal. This terminal is internally connected to one of the other two terminals, call them "A" and "B", depending of the position of the switch. A three way switch is connected with the circuit breaker connected to the "C" terminal on either switch. Conductors connect the "A" terminal on one switch the the "A" terminal on the other switch and the "B" terminal on one switch the the "B" terminal on the other switch. The remaining "C" terminal is connected to the "phase" or "power" terminal of the fixture. The other terminal of the fixture is connected to neutral. Note that, in either case, there is no neutral wire connected to the switch. Ground conductors do connect to the chassis of the switch box and the fixture, but they do not carry current and do not affect the operation of the circuit.
On the side of the coil there is a little terminal if you take a wire form that to a switch and the other terminal on the switch and earth it out on the chassis..
If you can get to the starter, you hook up one side of the switch to the terminal that goes to the battery and the other side of the switch to the small terminal marked with and "S". "S" is for starter. The other small terminal you leave alone. Applying power to this terminal will damage the starter.
To wire a bilge pump with a float switch to a toggle switch, connect the positive lead of the battery to one terminal of the toggle switch. From the other terminal of the toggle switch, run a wire to the positive terminal of the float switch. Finally, connect the negative lead from the bilge pump and float switch directly to the negative terminal of the battery to complete the circuit. Ensure all connections are secure and insulated to prevent any electrical issues.
An intermediate or 4 way light switch has 4 terminals + 1 ground terminal.
To wire a switch to a light, you connect the hot wire from the power source to one terminal on the switch, then connect another wire from the other terminal of the switch to the hot terminal on the light fixture. Finally, connect the neutral wires from the power source and the light fixture together.
The switch is not needed.

On a single pole single throw there is no common terminal. On a single pole double throw it is the terminal that is common to both the top and bottom terminals. The "hot" wire is connected to the common terminal so that when the switch is in the up position that terminal becomes energized and there will be no no voltage on the bottom terminal. When the switch is in the down position the bottom terminal becomes energized and there will be no voltage on the top terminal. In relays thisis known as a C form configuration.
To wire two single-pole switches (interruptors) for controlling the same light fixture, connect the power source (live wire) to the first switch's input terminal. Then, run a wire from the first switch's output terminal to the second switch's input terminal. Finally, connect a wire from the second switch's output terminal to the light fixture's terminal. Ensure all connections are secure and that the circuit is de-energized while working.
