►UJT Actuator mounting positions To calculate force Divide the switch force by the coefficient given in the table. To calculate travel Multiply the switch travel by the same coefficient. Example: 83 161 3 with lever 161 A - R 25.4 position A (coeff. 4) Operating force: 0.8 : 4 = 0.2 N Overtravel: 1.2 x 4 = 4.8 mm O Thread length C Total travel Other shapes and dimensions: consult us Also available are pinned actuators mounted on position D (factory mounting), same as for 83160 series.
