Optional Features:

Momentary Switch: A momentary switch changes state during activation and reverts to its original state upon deactivation. A doorbell is a common example of a momentary switch. A timer can be used to extend the effect of the switch operation for a specific amount of time.

Alternate Switch (A): An Alternate Switch changes state upon activation and does not change back until reactivated. A light switch is a common example of an alternate switch. Alternate switches are also called maintained or latching switches.

Single Pole - Double Throw (SPDT): Switches with one input and two outputs. When the switch operation occurs, the connection shifts from output A to output B.

Double Pole - Double Throw (DPDT): Two SPDT switches that operate in tandem using one switch operation so that each connection shifts simultaneously from its primary output to its secondary output.
