QSA Series

     QSA  Series have five features or benefits:(1) Excellent tactile feel(2) Plunger can be custom designed(3)SMT switch adapted for low current(4)Only actuate 1 direction at a time(5) Provides logic level control.
      There are five Typical Applications of QSA  Series.The first of all is that it has Seat adjustments.The second is that it has Industrial controls.The third is that it has Mirror adjustment.The forth is that it has Home entertainment.The fifth is that it has Multi-function steering wheel.
      The following is about Construction of QSA  Series.The FUNCTION of QSA2 is it has 2 way switch while QSA4 has 4 way switch.The TYPE OF SWITCH of QSA2 is that it has 2x make contacts while QSA4 has 4x make contacts.The FOOTPRINT is 23 mm x 18 mm, operating direction diagonal.The Housing of HEIGH is 9 mm, and total height is 22,4 mm .The PINS is Solder pins, SMD.Snap-in pegs provided to help secure and locate switches.The OPERATION DIRECTION is that In X-Y direction along the diagonal axis of the switch. Rotation point is 5,5 mm over the PCB surface. Travel of the actuator is measured on an axis parallel to and 19 mm above PCB.switch point/stop (4,0 N force)is 1,5 ± 0,4 mm / 2,0+0,3 mm.TACTILE EFFECT is more than 15%.The LIFE is 100,000 cycles in each direction( 20 N force). The RETURN FORCE is 0,8 ± 0,3N.The ACTUATION STRENGTH is more than 50 N when it is parallel to PCB,more than 100 N when it isvertical (push) to PCB,and more than 50 N when it istraction (pull) force.The maximum of SWITCHING POWER is 0,20 VA.The minimum of SWITCHING VOLTAGE is (VDC) 20mV while the maximum is 30 V.The minimum of SWITCHING CURRENT is (VDC) 1mA while the maximum is 50mA.The OPERATING TEMPERATUREis from -40°C to 85°C while STORAGE TEMPERATURE is from -40°C to 95°C.
