As the controlling part of pressure systems, the performance of KBQ-02B series pneumatic switches is stable and reliable. The switch can be used to test positive pressure or negative pressure nearly without any lag. The design of the switch makes its air interface rotate any angle. In addition to directly welding on to printed circuit boards, the connection also fits to electric wires and inserted terminal.
