[Connect to the relay]
This series of switches supports the relay alarm function, and the wiring
terminals use 3-position 5.08mm pitch terminals. This relay is a normally
open and a normally closed relay, the middle one is the common terminal, the
left two terminals are normally open relays, and the right two terminals are
normally closed relays. When the switch is working normally, the normally
open relay is powered and closed, and the normally closed relay is
disconnected. The recommended switching load capacity of the relay is 1A
(24VDC).
