Relay Sockets

Mount to 35 mm DIN rail or flat surfaces, then plug your relay into these socket for fast installation.

Recessed terminals prevent contact with live connections.

Hold-down clips (sold separately) secure the socket in applications subject to vibration.

Thin Spade-Terminal Relays

8-Terminal Relay

Thinner than other spade-terminal relays, these fit in tight spaces. Attach quick-disconnect terminals or plug relays into relay sockets. Use them for low-current switching applications such as small motors and pilot lights.

Relay sockets with screw terminals (sold separately) mount to 35 mm DIN rail or flat surfaces.

Relay sockets with spring-clamp terminals (sold separately) mount to 35 mm DIN rail.
