yes
A circuit diagram could be related to a closed circuit if the diagram is of a closed circuit.
when the pressure switch detects some pressure it turns the circuit on and sometimes depending on the programming in accordance with the amount of pressure it could do different things.
There are two kinds of circuit closed circuit and open circuit
you put 2 holes in a cardboard box. Next, you put the nails into the holes, and finally, place the paperclip in between the 2 nails, connecting.
A circuit is complete whenever current can flow from the battery (or what is producing current), through the circuit, and back to the battery. A complete circuit could contain just a battery and one wire. An incomplete circuit could be a battery with a wire attached to just one terminal, because current cannot flow all the way through the circuit in this case (i.e. cannot flow through the battery). note: not all elements in a circuit may have current flow in a complete circuit. For instance, a light bulb may be shorted but you still have a complete circuit.

sirs if you could explain me detail about the staircase lighting ckt diagram & explain how does the switch function.
Switch
Depending on where in the circuit the screw driver is placed it could be used as a switch or it could short the circuit out.
Generally a circuit breaker (like a light switch) But I guess you could use a resistor of the right resistance If you are talking about the circuit breaker there is an electromagnetic coil in it which get magnetized on a specific amount of current and breaks the circuit
Could be an inductor / coil, without metal core.
A time activated switch could use pneumatics or an resistor capacitor circuit.

Please see the related link below for the only detailed diagram I could find
A switch in a circuit will quickly allow you to break the circuit, without changing the wiring. For example, a light switch. By turning a light switch off, you are breaking the circuit and, thus, turning the light off.
An open circuit is one where the current is not able to complete the circuit. An example could be a light bulb connected to power but switched off, the circuit being broken by the switch, and considered "open." When flipping the switch On, it connects the power and the circuit is then closed.
I find a good way to revise is to make flash cards with the things you have to learn on them, and then stick them around your house. For example, if you were revising for a science test, and you were studying circuit symbols, you could put the circuit symbol for switch next to a light switch. Hope this helps you revise, and good luck in your test/exam(s) :) Source: Me
