I need to source a very small thermal switch that would fit beside a peltier and open at approx 50 C.
This is to prevent someone from getting a burn. I was thinking of the small battery cut offs but I do not know if they reset once opened. The smaller the better as it would be ideal if it was flush with the peltier. I would like to wire it to the power source as a simple mechanical thermostat.
Power supply ranges from 5V, 500ma to 13V, 1A.
It needs to be simple as there is no logic board.
