Standard Single Pole Double Throw (SPDT) slide switch.
Pin names
| Name | Description |
|---|---|
| 1 | Left terminal |
| 2 | Common terminal |
| 3 | Right terminal |
The slide switch has three pins. Pin 2 (in the middle) is the common pin. Depending on the position of the switch's handle, it's connected to either pin 1 or 3:
| Handle position | Description |
|---|---|
| Left | Shorting pins 1 and 2 |
| Right | Shorting pins 3 and 2 |
The following diagram illustrates the connections inside the slide switch. You can see the gray sliding contact that moves together with the handle and creates a connection between pin 2 and either pin 1 or 3:
Attributes
| Name | Description | Default value |

Bouncing
When you move a physical slide switch, the circuit opens and closes tens or hundreds of times. This phenomenon is called Bouncing.
Wokwi simulates switch bouncing by default. You can disable the bouncing simulation for individual switches by setting their "bounce" attr to "0":
{ "bounce": "0" }
