SP series Washable snap-action pushbutton switches DISTINCTIVE FEATURES Process sealed Front and rear sealing Process compatible (plain bushing models) Wave solderable Washable ELECTRICAL SPECIFICATIONS Max. current/voltage rating with resistive load : - gold plated brass contacts : 100 mA 30 VDC - silver or gold plated silver contacts : 1 A 30 VDC Initial contact resistance : 50 m max. Insulation resistance : 1,000 M min. Dielectric strength : 1,000 Vrms 50 Hz min. Electrical life : 60,000 cycles ENVIRONMENTAL SPECIFICATIONS Operating temperature : -20 C to +85 C (-4 F to +185 F) Storage temperature : -40 C to +85 C (-40 F to +185 F) Moisture : The insulating materials employed and the complete seal permit the switches to withstand a 56 days moisture test (IEC 68-2-3). Solderability : The switches are tested at 235C according to IEC 68-2-20 after accelerated aging. GENERAL SPECIFICATIONS Torque : 0.25 Nm (.18 Ft.lb) applied to nut (threaded bushing) Total travel : 0.50 mm (.019) Mechanical strength : Terminals are strengthened by a bracket or a ground plate ensuring the rigidity of the switch on the board. Actuator strength is 10 N max. Soldering - thermal shock (plain bushing models only) : The switches are especially designed for flow soldering at 260 C (500 F) during 5 seconds owing to high temperature polymer parts. Iron soldering (threaded bushing models) : 300 C (572 F) max., 5 seconds max.
