Special Features:

Standard adjustment rante of pressure difference: 1 - 20 psid, make/break differential - spst; 3 - 9psig, max system pressure (psig): 50, max pres (psib); 80, bellows diameter 1 - 3/8", 222-32 series switch is intended for use on vessels having an annunciator panel (spec. Mil-a-17196) with a supervisory circuit continuously indicating whether ships wiring between the panel and the alarm switch is in working order. To provide for this feature a navy-approved resistor is connected across the terminal screws. This resistor is easily removed when the switch is used on panels w/o this supervisory circuit.Available in non-magnetic (brass) models when specified (less than 2.0 magnetic premeability).

Properties:

A switch that is actuated by changes in ambient temperature. Excludes circuit breaker; control, temperature (as modified); fuse (as modified); protector, thermal-overload, electrical motor; relay, thermal; and thermostat, flow control. See also control, temperature (as modified) and regulator, temperature (as modified).
