The Dwyer Instruments 1910-1 is a differential pressure switch for marine control systems. It compares the pressure at two points and changes its electrical contact state when the difference between them reaches the switching point, giving the control system a simple on/off signal. The unit handles a maximum pressure of 45 in. W.C. and a surge pressure of 10 psi, with a maximum temperature of 82°C. Field wiring calls for No. 14 AWG copper wire rated 90°C minimum. Made in the USA, this switch is supplied in new open box condition.
