TH16 as a N-O Switch


Recommended Posts

I needed a temperature control 12 volts switch. So I modified my TH16 circuit board as follow:

Using a Dremel, I cutted the circuit on both sides (IMPORTANT) between the relay and resistor and soldered a jumper 14 ga between the ground terminal (not in use) and the relay . The result is a Normaly Open contact to control my 12 volts circuit.

One of the 2 N/O contacts should have been identified as C for Commun. 😊

Do this at your hown risk!
