The ASCO JB67A218A is a Tri-Point miniature pressure switch designed for precise low‑pressure control in compact systems. It features a 1/8" NPT connection with a normally open contact and is rated for 5 A at 250 VAC (and 28 VDC), with screw terminals for straightforward wiring. The non‑adjustable device has a set‑point range of 6.5–8.5 psi (psig) and a fixed deadband, using a brass body and Buna‑N diaphragm/piston sensor. This compact switch is ideal for monitoring and signaling in small pneumatic circuits operating within the 6.5–8.5 psi range.
