MINI VOX AND RELAY KIT

Stock Number:
2061-EA1

---

The idea behind a VOX (voice activated switch) is that instead of the user pressing a switch to activate a relay, the sound of the users voice itself activates the relay. This gives hands-free control over devices like tape recorders. Power supply needed: 12VDC center positive 2....More
