Emergency pushbutton switches are an important part of any control system. They are ideal for protecting personnel and property, allowing the user to press the buttons for emergency stop/ventilation control, in addition to triggering the relays through the gas detection system. The Emergency-Stop, EmergencyVentilation and Emergency Pressure Control switches can be used with 24 VDC or 120 VAC, and have two sets of 1.5A contacts. The Tamper-proof flipcover meets most new codes, including IIAR-2 2014. The switches are housed in a durable NEMA 4 polycarbonate enclosure, able to withstand weather and washdown environments for indoor or outdoor mounting applications. Mounting flanges are also included for easy installation.Features:40 mm push/pull latching mushroom pushbutton switchTamper-proof clear switch coverIP66/NEMA 4 weatherproof design for outdoors or washdown environments120 VAC or 24 VDCCircuit board with terminal block for wire landingsMounting flanges for wall mountingSolution for Compressor Room E-stop / E-vent / EPCS applications
