pushbutton switches Series 59 Miniature Sealed Pushbutton Switch Typical Applications Communications Instrumentation Data processing Process control Transportation/material handling actual size Features Description Nonspark material The Series 59 has been designed as a miniature, rugged, front panel sealed Wide temperature range: pushbutton switch, ideal for harsh Up to 125C (257F) Form X environmental applications in limited Panel sealed: To IP67 space envelopes. High environmental specification The body of the Series 59 is made of a Impact resistant special high creep strength nonspark zinc alloy, suitable for use in the mining Gold contacts industry and other potentially explosive atmospheres. Mounting Information This series comes in a standard round The Series 59 mounts easily into panels bezel version with solder terminals, 3 1 of minimum /64 and maximum /8 momentary action switching, and a thickness. Front panel sealing to IP67 is choice of three button colors. A locknut achieved by a sealing O ring fitted into is supplied with each switch. a machined groove on the body of the switch before it is inserted into the panel hole cut out. It is held onto the panel by means of a brass lock nut, 9 tightened down by a /16 wrench, to a torque of between 1,5 Nm to 3,0 Nm (1.106 f.p. to 2.213 f.p.) to achieve the correct sealing pressure. A D flat is provided to prevent rotation. It is recommended the switch cut-out be punched from front of panel.17.5 Electrical Data 17.5 DIA SQ .69 .69 Dielectric strength: 1,000 VAC Insulation resistance: 1 G Contact resistance (max): 50 m BUTTON COLOR 7.0 Life(max): 500,000 cycles max power BLACK BEZEL .28 ROUND BEZEL SQUARE BEZEL SEALING RING Switching power (max): 16 VAC (UNDER BEZEL) 7.0 BRASS LOCKNUT .28 Mechanical Characteristics 13.0 13.0 .51 .51 Travel (nominal): 0.090 in M12 X 1.0 BRITISH ISO METRIC THD Life (max): 600,000 cycles 4.5 REF (2) GOLD PLATED BRASS .18 SOLDER TERM (2) Operating Force (nominal): 3 N (10.8 oz) 13.5 17.5 DIA .53 .69 Contact Bounce (nominal): 1 mS DIA Panel Thickness (max): 0.118 in Environmental and Physical Data Ingress protection: IP67 OF IEC 144 HIGH ROUND BEZEL Shock: 100 G 7.3 .29 Operating Temp Range: 55C to + 125C (67F to +257F) 13.0 .51 Body Material: Zinc alloy, black anodized 5.1 .20 Button Material: PBT Contacts: Gold-plated palladium nickel Terminals: Gold-plated brass 12.95/12.90 .509 .001 millimeters inches 13.65/13.60 DIA .536 .001 RECOMMENDED PANEL CUT-OUT Electrical Characteristics Circuitry Current Voltage SPST-NO-DB 400mA 32 VAC Res SPST-NO-DB 100mA 50 VDC Res SPST-NO-DB 125mA 125 VAC Res Ordering Information Std.
