The LER00150TBPNKAAA20 is an LE Series electromechanical low pressure switch designed to activate an electrical circuit upon reaching a specific pressure. This model is factory-set with a non-adjustable, rising pressure set point of 15.0 psig (true gage). It features a single-pole, single-throw normally open (SPST-NO) output with gold-plated contacts for reliable switching. The switch is constructed with a durable stainless steel base, a 1/8-27 NPT port, a Teflon-coated Kapton® diaphragm, and a Nitrile O-ring. Connection is made via 1/4 inch spade terminals, making it suitable for applications involving air, petroleum-based hydraulic fluid, and engine oil.
