Switches with gold-plated contacts are intended for use in circuits where switching is at milliwatt levels. In this case, the power being switched must be limited to avoid the erosion of gold plate from the contact area. However, as the underlying contacts are silver, the same power ratings apply. 28 | 29 www.saia-burgess.com saia-burgess Switches 40621_Inhalt_029 14.10.2004 7:54 Uhr Seite 29 F4 Operating Characteristics Actuator Plunger Actuating Force Maximum (N) (ozf) Release Force Minimum (N) (ozf) Free Position Maximum (mm) (in) (mm) F4T6 F4T7 1,4 5,00 0,25 0,90 8,8 0,35 8,1 +0.3 -0.2 0,32 +0.01 -0.008 0,13 0,005 F4T6Y1 F4T7Y1 0,6 2,20 0,07 0,25 10,0 0,39 8,2 +1.0 -0.7 0,32 +0.04 -0.03 0,70 0,030 0,7 2,50 0,09 0,32 11,7 0,46 10,3 +0.8 +0.03 0,41 -0.55 -0.02 0,45 0,020 Reference Operating Position Movement Differential Maximum (mm) (in) (in) Over travel * 3.4 [0.13] 1.6 [0.06] Burgess Y1-Lever * 21.0 [0.83] 7.5 [0.3] Burgess Width of lever 3.0 mm/0.12 in F4T6YC F4T7YC YC-Lever R2.4 [0.09] 16.9 [0.67] * 7.5 [0.3] Burgess Width of lever 3.0 mm/0.12 in Operating characteristics are specified from the mounting holes. * Plunger can be depressed flush with housing.
