7 Pin Flat 'Quickfit' Trailer Socket with Reed Switch for use with Normally Closed Circuit. Designed for vehicles with reversing sensors, these sockets feature an in-built reed switch that deactivates the sensors while a trailer is connected. This prevents constant beeping from the sensors that detect the close proximity of the trailer. The reed switch disconnects the reverse sensor once the socket lid is opened for plug connection. .
The space allocated for the connection of the reed switch wiring is barely enough.
The method of sealing the socket is not positive and relies on the gland nut holding the 2 halves together which distorts the socket and can allow the ingress of water or dust.
