This rocker switch has a dual pole dual throw (DPDT) circuit in an On-Off-On configuration. DPDT switches are effectively two single pole dual throw (SPDT) switches toggled by the same physical switch. This means you can switch two different circuits with the same physical toggle.

The switch is designed to mount in a 20 x 13mm rectangular hole and features two tabs to help hold it in place. Connections are made via 1/8” Quick Connect / spade terminals on the back of the switch.
