289 dp indicating switch
The grip rotates in the counterclockwise path with increased stress. The tiny switch is positioned at a varying pressure of 25% and the raised knob is positioned at a complete pressure of 75%. Units are provided with either full or double alarm buttons and/or relays (based on client request). The direct-set button links can be adjusted over 5 times to 95 percent of the scale spectrum for SPDT devices and 6 percent to 94 percent of the scale spectrum for DPDT devices.
Switch touch longevity is affected by multiple implementation circumstances such as temperature, humidity, airborne contamination, vibration, quantity of plunger transport, cycling speed and frequency of plunger transport (and others), as well as electrical (device) features. The Drive Arm and Switch & Plate assemblies have been reworked due to the fresh snap-acting microswitch being used in the Model 289 variable stress showing tap. These units are not reverse compliant and must be mounted simultaneously for the correct function of Model 289.
