Technical Reverse Gear Switch issue????

[nikkiy9]

hey guys, for the last few days i have only had reverse sensors working once, other half went out to check after we had been for a drive, no reverse lights, then i tried a few more times for the reverse light to flash up once and also the reverse sensors to start beeping,

does this sound like a switch fault?

car is a JTD 115 with 114k on the clock
