Passive parts and switches
Resistors, capacitors, inductors, sensors, switches, relays and transformers.
Basics
| Part | Behaviour |
|---|---|
| Wire and Routed Wire | Connect terminals. Routed Wire bends around corners. |
| Resistor | Opposes current. Set the resistance. |
| Capacitor | Stores charge. Passes AC, blocks DC. |
| Polarized capacitor | An electrolytic type. Mind the polarity. |
| Inductor | Stores energy in a magnetic field. Opposes changes in current. |
| Potentiometer | A resistor with a slider. Use it as a voltage divider. |
Sensors and special resistors
| Part | Behaviour |
|---|---|
| Photoresistor (LDR) | Resistance falls as light increases. |
| NTC thermistor | Resistance falls as temperature rises. |
| Memristor | A resistor whose value depends on the charge that has passed through it. |
| Fuse | Breaks the circuit when too much current flows. |
| Spark gap | Conducts when the voltage across it is high enough. |
| Crystal | A resonant element used for accurate frequencies. |
Switches
| Part | Behaviour |
|---|---|
| Switch (SPST) | On or off. Click to toggle. |
| Switch (SPDT) | Connects one terminal to either of two others. |
| Push switch | Closed only while you hold it. |
| DPDT | A double-pole, double-throw switch. |
| Make-before-break | Connects the new contact before releasing the old one. |
| Cross switch | A reversing switch. |
Relays
| Part | Behaviour |
|---|---|
| Relay | A coil that closes a switch when powered. |
| Relay coil and Relay contact | The coil and the switch of a relay as separate parts. |
Magnetics and lines
| Part | Behaviour |
|---|---|
| Transformer | Two coupled coils. Set the turns ratio. |
| Tapped transformer | A transformer with a centre tap. |
| Custom transformer | A transformer with settings you define. |
| Transmission line | A line with a delay, for high-frequency work. |
| Gyrator | Makes a capacitor behave like an inductor, and the reverse. |
