Merc overheat switches & temp sensors

Does anyone know if the simple "on/ off" switches used for the overheat horns had a similar shape & mount to the temp. senors for the optional temp guage?

I ask because my clamshell doesn't have either. As I have a mount hole for the sensor, the spare cable for the optional temp guage in the remote loom & a buzzer in the 703, I am planning to fit a switch & get an overheat warning alarm. (No space on the console for a guage)

The only possible problem I can see is the hole for the temp sensor appears to have a tapered bottom (possibly for a small head sensor?) , and the thermal switches on both the Yam & the Suz had flat bottoms (presumably to get enough heat into them fast enough to make them throw?). Needless to say that's not going to be a lot of use if the "business end" of the switch isn't touching the head.......
