The Balboa Tecmark 3903-EADE pressure switch rated at 2 psi is mounted with a 1/8″ (10 mm) thread directly into the Balboa heater body. When the pressure changes, it opens or closes the electrical circuit, and the trip pressure can be set manually.
The switch maintains stability across a wide range of varying temperature and humidity conditions, as well as under extreme shock and vibration. It offers a service life of 100,000 cycles under full mechanical, electrical and thermal load, plus simple installation.
