Switches come in two basic types: Momentary Action and Alternate Action

• A momentary switch changes state during activation and reverts to its original state upon deactivation. ie: Doorbell Switch

• A timer can be used with a momentary switch to activate the switch contacts for a specific amount of time

• An Alternate Switch changes state upon activation and does not change back until reactivated. ie: Light Switch

• Alternate switches are also called Maintained or Latching switches

A (NO) contact means that the circuit is open and the voltage is not

transferred through its normal state.

Wired in Parallel for Fail Secure type electric locks.

ie: Electric strike

Activating any switch will apply power releasing the lock.

A (NC) contact means that the circuit is closed and voltage is

transferred through its normal state.

Wired in Series for Fail Safe type electric locks.

ie: Securitron Magnalocks

Activating any switch will break power releasing the lock.
