## **Inserting and removing method** 

Inserting method: Insert the relay as Rib shown in Fig. 1 unit the rib of the relay snaps into the clip of the socket. =i Fig. 1 

Removing method: 

(1) Remove the relay straight from the socket holding the shaded portion of the [ay Fig. 2 relay as shown in Fig. 2. (2) When sockets are mounted in close proximity, use a slotted screw driver as shown in Fig. 3.
