Drawing a pneumatic circuit diagram

[Didawdidaw]

Produce engineering sketches for the following:
A pneumatic circuit diagram comprising at least 6 different components using the appropriate standards, symbols, and conventions. It must include as a minimum: Reservoir, Filter; Actuator; Control Valve (of any type as long as the circuit is viable); Shuttle Valve, Switch (any type).

So far I have this below, but i dont know how or where to put in a switch and a shuttle valve. Just wondering if anyone can help me out, thanks,
