A pneumatic detector assembly (10) includes a housing, a sensor tube (40), a contact pin (24, 34), and at least one switch (20, 30) having a bellows (22, 32) operatively associated with the sensor tube (40) and the contact pin (24, 34). The bellows (22, 32) is configured to move into and out of contact with the contact pin (24, 34) based on a pressure in the sensor tube (40). |
